Mihato's Wooden Tablets, or, A Record of Thirty-Seven Generations
Book Three—Final
Foreword At the end of Chapter One of the main volume, Ran Hiiragi's record says: "I named my daughter MIHATO—child as clear as the water of this land." And the main narrative closes its eyes on her lineage. Thirty-seven generations. Roughly a thousand years. This thousand years, written nowhere in the main volume or the prequel, is written here. This is the record of a girl who lost her mother from the future at five, living with her mother's wooden boards without knowing her mother's face—and the record of how those boards continued to be protected for nearly a thousand years, even after losing their original meaning. History gets buried. Letters fade, names are forgotten, meanings change, but objects stubbornly remain. Mihato's story is about things that remain even after losing their meaning.
Chapter 1: Winter at Five Mihato lost her mother in the winter when she was five. No one remembered the exact year. Only that the winter had little snow, but a dry wind blew continuously, as the old later told. Her mother had a fever and died on the seventh day. Mihato didn't remember her dead face well. She only remembered: the day before her death, her mother took Mihato's small hands trembling, and washed them with hot water. "If you get a wound, always wash it with hot water." Mihato didn't understand the meaning yet. After her mother died, she was taken in by the older woman who had first picked up her mother in the marsh—called ANE in the village. Ane already had grandchildren, but raised Mihato like a real grandchild. Children sometimes called Mihato the strange girl from the north—an extension of her mother being accepted as the strange woman from the north who knew medicinal herbs. Mihato herself didn't truly know where her mother came from. Her mother had never told her details. Only, in a corner of the house, were many wooden boards her mother had treasured, densely carved with unknown letters.
Chapter 2: Unreadable Letters At ten, Ane said: "Your mother left something on those boards. When you grow up, try to read them for her." Mihato took the boards. Hard wood carved with a metal needle. Katakana—different from any language of the archipelago. At first she thought they were pictures—wave lines, deer horns, face lines. But the same shapes repeated many times. Gradually she realized they represented sounds. Her mother's small black board—a portable terminal from four thousand years in the future—had lost its light long before her mother died, becoming just a cold, heavy black stone. Mihato kept it as a keepsake with the wooden boards, but the black stone was lost over the years. Only the wooden boards carved by her mother's own hand remained. At fifteen, she asked an old shaman to write down fragments she remembered her mother sometimes saying—te o arau, netsu o dasu, mirai kara—matching those sounds with her mother's board letters, trying to assemble a reading. She could not fully read them. Still, she noticed some letter strings appeared repeatedly. te wo arau The same shape as the words her mother had repeated. Mihato became convinced the boards wrote about washing hands.
Chapter 3: Child as Clear At eighteen, Mihato married a young fisherman. Her husband didn't care about her origin. As her name implied—a child as clear as water—Mihato was known as a quiet, strong woman. She passed her mother's habits to her family: Wash hands before meals. Wash wounds with hot water. For a baby, always drink water once boiled. Village women called it the custom of the House of Ane of Ihato. Many had already forgotten who her mother was. Only a vague reputation remained: the house of the woman from the north, where people wash their hands since ancient times. Mihato bore three children. Eldest Mina, second Sayo, eldest son Takeru—names of this age, unrelated to the far future. She decided to entrust the boards to the eldest, Mina. "This is what your grandmother left. You don't need to read it. Just keep it safe." Mina nodded. She too could barely read them. Mihato died at forty-two. Not a short life for this age. At her dying moment, she told her daughters, as later family tradition recorded: "Even if the meaning of the letters becomes unknown, this is the warmth mother left us. Don't burn it, don't throw it away, don't lose it. Pass it to the next child. That's enough."
Chapter 4: Record of Thirty-Seven Generations (Overview) From here, reconstructed via family tradition and archaeological estimation, is a fast chronicle. After Mihato's death, the boards, as the Treasure of the House of Ihato, were passed to the eldest Mina's line. By the third and fourth generations, no one could read them. The letters were treated as a purification spell bestowed from a god or ancestors. In the seventh generation, the house left the village and moved to a larger chief's domain. For fear of burning during the move, the boards were placed in an earthen jar and buried under the floor. From then on, the boards became a secret—an unopened guardian spirit—known only to the head of the house. By the fourteenth generation, the house was known nearby as the House of Hand-Washing. Researchers later estimated that infant mortality in this household was slightly lower than in others. No one knew the reason. Only the habit survived as a daily ritual. In the twenty-second generation, the existence of the boards was secret even to some heads. One head misunderstood the boards as a foreign curse talisman and asked a village shaman to decipher them. The shaman couldn't, but warned: "These are terrifying god's letters; you must not touch them." The fear increased, but the boards were kept safe. By the thirtieth generation, the house was part of a powerful clan. The boards were stored in an unopened box deep within the hall of heirlooms. A woman of this generation reportedly opened it and saw the boards. A written fragment remains: "Left by ancestors. Cannot be read, but revered. Pass down without reading."
Chapter 5: End and After In the thirty-seventh generation, the house was caught in a large war. An enemy clan burned the hall, and many of the family were killed. The house effectively ended. After the hall burned, the jar buried under the floor remained in the soil for centuries. Later, it was excavated by a man of a completely different clan. He found the bundle of old wooden boards inside the jar. He could not read them. The letters were too old, too alien. He could not tell if they were ominous or precious, but hesitating to treat them roughly, he donated them to a nearby mountain temple. The temple stored them deep in its storehouse alongside other old offerings. As the storehouse aged and rotted, the boards mingled with other old documents, and eventually, no one cared for them. Epilogue: Like Clear Water What Mihato inherited from her mother was not letters. The letters became unreadable within three generations. What Mihato inherited, and what her descendants continued for nearly a thousand years—even while losing its meaning—was simply the act of keeping something precious safe. The meaning was lost. But the act remained. The habit of washing hands became a ritual, then a spell, and finally the enduring reputation of a household. The letters on the boards became a spell, a source of awe, and then quietly slept deep in a temple storehouse. The single unglazed jar excavated on the small Seto island that reached Division 7 in AD 4493 contained Shiori's letter and the records of the seven travellers. Ran Hiiragi's wooden boards, without ever reaching the conference room in the far future, still sleep deep in a nameless temple storehouse today—or perhaps have long since rotted back into the soil of the archipelago. Still, this book records: For thirty-seven generations, nearly a thousand years, a family continued to cherish an important thing without understanding why. It will never be in history textbooks. But that is how nameless people carry history. Mihato lived as her name meant. Clear water does not ask where it came from. It just keeps flowing, changing its shape from person to person, vessel to vessel. History is probably like that too. — End of Side Story —
Afterword With the main volume and the prequel, this side story concludes the trilogy. Biochemist Ran Hiiragi—a woman who stepped from the future into the ancient world—what did she leave behind? The main volume focused on her scientific knowledge and her message to the future: History with a capital H. What I wanted to depict here is smaller, but surer: history with a small h. The story of Mihato, the girl who lost her mother at five, is a story where advanced information like written letters and future science gets cut off. However, no matter how unreadable letters become and how completely meaning is lost, the memory of love handed down from parent to child, and a small habit like washing hands, survived a thousand years. History is not made only by heroes and grand events in textbooks. Countless baton relays of nameless people who continued to cherish important things without knowing their full meaning support the flow of time. With clear Mihato's life and the thousand-year quiet walk of her descendants in mind, I want to thank all the readers who accompanied this long journey.
Foreword This is the other side of the blue ring. Book One was about seven people who crossed four thousand years to live in fourth-century Japan. This book is about seven people who stayed in 4444, who watched them leave, and who waited. Why could the time machine only go one-way? Why did we keep sending people, knowing they would never return? And why did we stop at seven?
Prologue: The Institute June 17, 4444. Monday. Tokyo Bay was twenty-seven meters higher than four hundred years before. Old Shinagawa was underwater, with an artificial floating island drifting quietly above it. On the north end of the island stood a plain white five-story building. No sign. Officially: Temporal Engineering Institute, Division 7. Called "Nanabunjo"—Division Seven. Forty-six staff. On the first floor, a transfer room that smelled of hinoki cypress. In its center, a vertical metal ring two meters across. Not gray, not silver, but a kind of blue. Clear fluid ran slowly through thin tubes around it. When you passed through this ring, you went to the past. No one came back. What follows is the record of seven technicians and the people around them. They sent seven people—biochemist, kendoka, former SDF, linguist, chef, journalist, film director—one by one through the aqua-blue ring. And then they kept living. This is the record of why they could only make it one-way, and why they kept sending.
Chapter 1: Haruka Sakaki, Director Haruka Sakaki, 63, fourth director of Division 7. She joined as an assistant at 28. Husband none. Children none. Lovers—staff thought none. In fact, she had a lover when young. He volunteered for early time machine test. He was the first sent. To the Late Cretaceous. No news since. She never told anyone. One April morning, vice-director Yuji Maki entered with papers: selection plan for Subject No. 8. Sakaki read first line, quietly closed it. "Maki. We're stopping this." "Stopping?" "No No. 8. We end at seven." Reason: Last night, she dreamed. In the dream, her lover stood in a Cretaceous swamp, still thirty. He smiled. "Haruka. It's enough. Stop sending. It's not so bad here. I'm happy. You be happy over there." She woke. Decided: freeze the project. At noon June 17, she would tell all staff.
Chapter 2: Satoru Tsuruoka, Chief Theorist Satoru Tsuruoka, 51, highest authority on time physics. His official answer to why you can go to past but not future, and why you can't return: "We don't know yet." He said it sixty-seven times. On June 16, Sunday, he reread a paper he'd written for seven years, unpublished: "The Origin of Non-Reversibility in Temporal Leap: The Double-Wall Hypothesis" It said: Temporal leap is reversible in principle. You could bring them back. But our ring-liquid acceleration method—the blue ring—intentionally destroys reversibility. Why? Reversible method creates quantum entanglement between sender and sent. The moment the sent person performs a decisive conscious action in the past, it backflows to sender. Simulation showed sender-side apparatus and technicians spatiotemporally vanish. Therefore we abandoned reversible. We intentionally chose one-way. Not failure. A choice to protect senders. Cost: sent person becomes permanently embedded in past spacetime. Their consciousness embedded where they lived and died. Not metaphor. And—when they leave writing, it affects us via two routes: Normal archaeological route—physically survives four thousand years. Quantum direct route—via weak residual entanglement, writing can appear directly at specific coordinates in our time, if: (1) content contains explicit call to senders (2) medium survives four millennia unbroken (3) burial spot lies on short-circuit path to sending coordinates He had hidden paper seven years. Fear of expectation. Fear of answer: what to say if call comes? "Welcome to 4444" or "Forgive us for sending you one-way"? On June 16 evening, he took the thick paper bundle to Sakaki. "I'm going to publish this." Sakaki read title, didn't move. "Why now?" "Last night, I dreamed." She smiled a little. "Coincidence. Me too." Their dreams—told at end. That night, Tsuruoka told Sakaki: redesign quantum antenna to receive writings, discuss what to answer if call arrives. At 11pm he left institute, crossed bridge, looked at dark water. "We sent them. If something arrives, we must receive it."
Chapter 3: Chinatsu Misawa, Transfer Operator Chinatsu Misawa, 29, chief operator. Her job: move blue ring. She sent all seven. She pressed button seven times. Watched seven disappear. At interview at 24, examiner asked: Can you send people? Those sent never return. Your button is last button of their life. Still press? She answered: "I can. Condition: after I send seven, send me as eighth." Recorded, but never clearly accepted. She told no one. She had lover, loved him, but planned to vanish. Why? "The person who saw their last faces must be in same time and place as them, or they'll be too lonely." Night she sent seventh, Akira Suwa, she stayed alone. "Akira, please draw over there. Probably no one in four thousand years will see, but I will remember that you drew." She remembered each day: 1st Ran Hiiragi, March 12, 4440, cloudy, small nod. 2nd Takeshi Mohri, Sept 3, 4440, sunny, came in keikogi, seven deep breaths. 3rd Osamu Kubota, Feb 8, 4441, snow, checking gear till last second, never looked at her—kindness. 4th Chiaki Yakumo, July 19, 4441, sunny, only one who said Thank you. 5th Gen Mizushima, Jan 26, 4442, sunny, gave her two onigiri he made last night. 6th Shiori Nonomura, Nov 10, 4442, cloudy, stared, asked: Are you planning to come too? Misawa didn't answer. Nonomura smiled: If you come, find small island in Seto. I think I'll be there. 7th Akira Suwa, May 4, 4443, sunny, stared, said: Your face now—I think I'll draw it over there. What's your name? Misawa Chinatsu. Now June 16, one year one month twelve days since seventh. She planned to volunteer as ninth after eighth. She didn't know next day at noon, Sakaki would freeze project. She stood before blue ring. "Everyone, someday I'll go. Find you all. Even one or two. Then say: I sent you. I'm sorry." Ring was slightly warm to touch.
Chapter 4: Yuko Sakaki, Training Supervisor Yuko Sakaki, 59, training supervisor. Four years younger sister of Director Haruka. She trained all seven for one to two years, tested physical, mental, acceptance of no-return. Each spent last week alone with her—officially final adaptation, actually farewell. Same final question to all seven: Why are you going? Ran: In 4444 I felt no meaning. Memorizing gut bacteria never saved anyone directly. Over there, maybe one or two. Takeshi: Wanted to test kendo in real combat when young. Still want to. Osamu: I'm good at living alone. Lived alone in 4444. A little more meaning over there alone than here alone. Chiaki: Want to see language disappear. In 4444 languages disappear and I can't record. Over there maybe I can. Gen: Ingredients in 4444 are poor. Over there rich. And—my customers in 4444 consumed cuisine, didn't need it. People over there probably need it. Shiori: Because I'm journalist. If there's blank, journalist goes to fill it. Even if can't fill, fact of going makes journalist. Akira: Somehow. Sorry, only that. Directors move somehow. Yuko wrote all in old leather notebook, mother's keepsake. Night after seventh, sisters had monthly dinner at Haruka's small apartment. Yuko cooked. "Number eight progressing?" Yuko. "Progressing." Yuko: "I think we should stop." Haruka: "Reason?" "Seven went intending to become people of there, not giving up living in 4444 but feeling they lived in wrong place, wrong time. They thought they'd finally live as themselves over there." Haruka nodded. "I'm thinking same. Tomorrow, I'll freeze." Yakumo's words to Yuko before ring: "You trained us to be sent. Did you train yourself not to be sent? We go. You remain. Remaining is probably harder. Going is decided by 'never return.' Remaining requires infinite renewal of 'must keep living.'" Yuko cried. Yakumo stroked her head. "We remember you. Even over there."
Chapter 5: Nao Dojima, Budget & PR Nao Dojima, 37, alone handled budget and PR. Not technician but 事務官. Without him institute didn't function. Nine years, lost quarter hair, antacid three times daily. Daughter seven. Wife gave up two years ago—not divorced but ten days a month at parents'. June 16 Sunday, making Q&A for budget hearing Monday. Q1: Seven sent, none returned. Failure? A: Return was known premise. Not failure. (Truth: by definition of failure, it is failure) Q2: Meaning of researching past with this budget? A: Filling blank essential for self-understanding. (Truth: no one here can answer) Q3: Compensation for families? A: Lifetime salary lump sum per regulation. (Truth: money can't compensate) He stared at ceiling. "It's over." He wanted to quit. Thought: blank will never be filled. Can't confirm filled because no return. Claiming filled is fraud. Nine years PR for fraud. Next morning planned to submit resignation. In drawer, photo: family of four—him, wife, seven-year-old daughter, and son who died at five. Congenital heart. Even 4444 medicine couldn't fix. Died week after fifth birthday. Two years before Dojima joined institute. Why did he join? Sometimes thought: Where did five years with son go? Time doesn't disappear. If time remains somewhere, son still exists somewhere in that remaining time. He wanted to believe that. He looked at photo, put resignation back. Wrote new paper: Proposal to freeze sending, redirect all budget to receiving writings from seven. Reason—night he dreamed. Dream told at end. He put paper in bag, turned off light.
Chapter 6: Sota Fushimi, Maintenance Tech Sota Fushimi, 42, responsible for blue ring. Knew it more than anyone. Composition of ring liquid (classified), micro-distortion, EM interference, and—sound ring sometimes makes alone. He treated ring as living. Called it KYOKA. Never decided kanji—just Kyoka. At night, alone, talked to it. "Kyoka, today we sent Kubota. You felt his tension?" Flow rate changed slightly before and after each sending. Different per person. Ran: slow regular. Takeshi: steep strong. Kubota: restrained quiet. Chiaki: elegant complex. Gen: warm gentle. Akira: wavering deep. Shiori: sharp precise. Interpretation: ring remembers subjects. Tsuruoka listened, said officially can't support, no physical basis. Unofficially, I don't deny. I've observed seven years. June 16 night, Fushimi sat before ring. "Kyoka. I decided today. Tomorrow I'll tell director: stop you." Ring silent, but flow changed slightly. "You're holding memory of seven. Don't want to erase. But each additional sending increases memory density. I'm scared you'll change. My gut. No physics." Before Akira vanished, he asked: Maintenance guy, this ring, nice ring. I'll probably draw this ring over there. What color should I draw? Fushimi answered: Blue. Not just blue, but blue of existence. Akira smiled: Blue of existence, got it. Will draw so. Now looking at blue.
Chapter 7: Tadashi Nanao, Archivist Tadashi Nanao, 24, youngest staff. Job: record everything. Minutes, sending details, final interviews, daily status, casual conversations. Small recorder always in chest pocket. Everyone trusted he wouldn't leak. Why archivist? His father was second-gen maintenance tech of institute. When Tadashi six, father vanished in accident—caught in predecessor ring while maintaining, sent to 17th century somewhere. Body never found. Mother raised him, died when he nineteen. Alone. Applied: Not to find father's whereabouts—understand can't. To not increase people like father. Recording deters, makes people careful. Five years, astonishing amount: Paper notebooks 427 volumes. Digital text 60 million characters. Audio 14k hours. Photos 120k. Goal: make record lasting 4000 years. Asked Tsuruoka: How make 4000-year record? Answer: Carve in stone, but must summarize extremely short. 60 million to how many? Probably 7000 characters. He started "7000 Character Project"—summary of seven years 4438-4444, 46 staff, seven sent, names, roles, interview summaries 570 characters each. June 16 night, printed latest draft, envelope wrote: To someone 4000 years later. Next morning planned to give to Sakaki, ask: Please carve in stone, bury under institute. In 4000 years excavated. June 17 morning gave. Sakaki read, smiled slightly. "Instead of stone, better way: wait for quantum reception of seven's writings." Nanao: Probably won't arrive. Extremely low probability. Sakaki: Yes. But not zero. If arrives, 7000 not needed. If not, carve your 7000. Either way your five years not wasted. Nanao nodded: Understood. Then I'll wait. He waited 49 years. Oldest. White-haired, single, still archivist at 73.
Epilogue: Three Dreams, and Noon June 17 June 16 night, three dreamed. Haruka Sakaki dreamed of young lover in Late Cretaceous, still 30, in wet forest. He smiled: Haruka. Enough. Stop sending. It's not so bad here. I'm happy. You be happy there. She woke, decided: No No. 8. Satoru Tsuruoka dreamed continuation of paper he hadn't written: "Condition for quantum reception: when sender explicitly abandons sending, only then writing from sent side may reach sender via quantum route." He woke, decided: publish paper. Nao Dojima dreamed of dead son, five years old, in his 4444 living room. Son smiled: Papa, time doesn't disappear. My five years didn't disappear. It's still there. So stop making other people go search. I'm here. He woke, looked at wife's back (she had returned from parents' that day), decided: not quit, propose freeze. June 17 Monday noon. 46 gathered in conference room. Haruka at podium, no manuscript. "Everyone. Today, we officially freeze sending plan." Silence. "Many reasons. Biggest: seven already live enough. We need not inject additional future people into their world." Continued: "Our job from now is to wait. Wait for writings of seven to arrive. May take decades. Some of us will die before it arrives. I probably will die before. But this institute will survive until it arrives. We will wait." Deep bow. "Thank you till now. And please stay with waiting. Thank you." Silence, then applause, long. That night, Fushimi sat before blue ring. "Kyoka. From now you sleep. Sleep and wait for seven's writings to arrive. I'll wait with you." Ring silent, flow changed slightly. After, Division 7 became Waiting Institute. No more subjects sent. Ring maintained carefully by Fushimi. Blue, quietly humming. Haruka lived 21 more years, died 84, told successor: Please wait. It will arrive. Tsuruoka published, caused shock, but didn't join debate much, retired quietly 67. Chinatsu stopped sending, worked under Fushimi maintaining ring, married lover at 40, bore daughter at 42, named Nanatsu—to not forget seven. Yuko stopped training subjects, started training of remaining—how to remain—taught technicians and families of missing subjects. Lived till 76. Dojima didn't quit, kept securing budget for waiting. Lost half hair, died 59 heart attack, wife beside. Fushimi kept maintaining, talking to ring, retired 63, said at retirement: Kyoka, I can't come anymore. Leave to young. But I won't forget you. And Tadashi Nanao. Youngest, waited longest. 49 years. August 17, 4493. Division 7 still there. Twelve full-time staff. Budget kept thin by successors of Dojima's successors. Ring maintained by successors of Fushimi's successors. Nanao 73, still archivist, white-haired, single. Morning, 10:32 AM, found unglazed jar on his desk. Old, clearly 4000+ years. Mouth sealed with wax. Trembling, peeled wax. Inside: tablets, bark paper, and a letter on washi containing the records of all seven. Letter began: To everyone in 4444, He couldn't read at first, vision blurred with tears. Sat, took seven deep breaths, then read. Finished at noon. Placed letter politely on desk, stood, walked corridor bright with August sun of 4493. Knocked director's office. Young new director, 34, Nanatsu Sakaki—daughter of Chinatsu Misawa. "Director." "Yes." "It arrived." That evening emergency conference convened, lasted three days three nights. Fourth morning conclusion: Artifact authentic. Letter authentic. But not public. Reason written in third point of letter: Blank may be left blank. That evening, Nanao went to transfer room. Ring still quietly humming. Sat before ring. Spoke name Fushimi used, first time aloud. "Kyoka. It arrived. 4133 years later, arrived. Waiting was worth it." Ring silent, flow changed slightly. He felt it. That night, returned home, took blank paper, started writing: "Waited 4133 years. Arrived. Writings of all seven people, centered on one letter as representative. All already dead from our perspective. Only one who remembers them alive is probably me, Tadashi Nanao, in this institute. I too will die in few years. So I write. I leave written—" What he started then is this Prequel. He retraced 46 people's records, compiled as group drama of seven technicians. Five years to complete. Entrusted manuscript with his will to Nanatsu Sakaki. She stored in dedicated vault under Division 7. On vault door carved: We sent them. What arrived, we received. Tadashi Nanao died five years later, 78, single. On his desk: pencil, blank paper, and small bottle of blue paint called blue of existence. He sometimes opened it, took small blue on fingertip, placed dot on washi. His washi had countless blue dots. Each dot, probably trace of 46 memories. And seven of them connected to marsh and king's hall and mountain cave and small island in Seto and some riversides and detached room in Yamashiro. — End of Prequel — We sent them. What arrived, we received.
Foreword History sometimes has holes so vast you could fall through them. Dig the earth and you find pottery, iron, bone. But soil does not speak names. Who loved whom, who wept for whom—eras without writing keep their mouths shut. In AD 4444, humanity finally built a time machine that could only go one way. Seven men and women left, knowing they could never return. This is a record of the small journals and a single letter that reached the world four thousand years later. Not a grand adventure that solves the riddle of history, but a quiet record of love and life.
Prologue AD 4444. Earth was, somehow, still there. The sea had risen three times and fallen twice. Cities had mostly migrated north. Countries near the equator had long since abandoned the word season. Humanity had six footholds on the Moon, two on Mars, one in the Jovian system—none of them true colonies, just shabby insurance policies. In such an age, the time machine was invented. Only it wasn't finished. You could go to the past. You could not go to the future. And once you went, you never came back. In sixteen years, thirty-seven people were sent out. Thirty-seven disappeared. And yet the scholars did not give up. Especially historians of Japan. Because this country still had a hole that had never been filled. From AD 266 to AD 413—147 years. For 147 years, almost no record remains of the Japanese archipelago. At a certain point the name of this island simply vanishes from Chinese chronicles. The next time it appears, there are the Five Kings of Wa, and somehow there is iron and horses and enormous tombs. "We need names. And faces. And voices." So seven were chosen. A biochemist, a seventh-dan kendoka, a former SDF officer, a linguist, a chef, a journalist, and one film director who had wandered in. On a June morning in 4444, in a transfer room that smelled of hinoki cypress, they were pushed one by one into somewhere in the archipelago around the year 300. No one came back. What follows are seven records that finally reached 4444, a thousand, two thousand, three thousand, four thousand years later. The point is the last letter.
Chapter 1: Ran Hiiragi [Audio transcription / Spring, AD 301] By the third day, I understood my field was almost entirely useless. In 4444 I could recite three thousand species of gut bacteria. Here, I am just a pale, thin woman who runs a fever. I landed in a marsh. Four women found me. They laughed kindly and took me in as the strange woman who drifted from the north, who is a little crazy but knows medicinal herbs. About seventy lived there. I decided to share only knowledge that could not harm this age. So first, I washed my hands. With water and ash. Before meals, when wounded, before touching a baby. At first they laughed. Then one copied me. Then three. After six months, fewer children died. Just a little. I decided to bet my life on that little. In my third year, I married a hunter. I will not write his name. In my fourth year, I bore a daughter. I named her MIHATO—child as clear as the water of this land.
Chapter 2: Takeshi Mohri [Ink on washi / Summer, AD 309] I am a seventh-dan kendoka. Kendo is not very useful in real combat. Mindset is. Maai, breath, zanshin. Those saved my life. The first man I killed was twenty. I shot him with the pistol. Three meters. Then I vomited for two hours by the river. The pistol had thirty rounds. I used them in two years. Now I serve a king. He calls himself OHO-HIKO—Great Prince. He saw my pistol once and understood: the difference between those who have it and those who don't. I fought for him. I have come to love him. He will bind the eastern half of this archipelago while I live.
Chapter 3: Osamu Kubota [Charcoal on bark / Autumn, AD 308] Take a projectile weapon and you'll be fine, they said. I landed halfway up a mountain. I decided not to contact humans. One cough from me could erase a settlement. So I lived alone. First year was hell. Third year, I snuck into a settlement and stole nuts. I left needles as payment. I became the first yokai of Japan. This quiet trade lasted ten years. Tenth winter, I caught pneumonia. My antibiotics had expired. On the fourth morning, a woman stood at the mouth of my cave with hot soup. She brings soup every morning. I don't know her name. She puts a cold cloth on my forehead. I hold her hand. That's enough to be happy.
Chapter 4: Chiaki Yakumo [Ink on wooden tablets / Winter, AD 325] As a linguist, I thought I had the most luxurious position. I could confirm the origin of Japanese with my own eyes. I landed on a small island in the Seto Inland Sea. Population forty. Three languages mingling. I was dropped into the front line of language contact. The language here is not the direct ancestor of Japanese in 4444. It is one of many. My island's language will be swallowed and disappear. I am recording a language that will disappear. I made sixty-one symbols, like waves and deer and faces. I teach them to children. My symbols will be used for two or three generations, then disappear quietly with the island. Even so, it's good if they could write before they disappeared.
Chapter 5: Gen Mizushima [Dictated / Spring, AD 331] I'm a chef. Three Michelin stars in Roppongi, 4444. Six-month waiting list. I landed on flat land. Everything is here. I wept. In 4444, 80% of fish farmed, vegetables greenhouse-grown, meat cultured. Three days after landing, a woman picked me up. That evening I cooked for her family: marsh herbs, three small river fish, my salt from 4444. Clear broth. Her mother took two sips and burst into tears. The concept of dashi did not yet exist. I taught them to dry fish, shave it, boil it. After three years, most houses had soup. After five years, I was summoned to the big man's hall. He said, Make this for me every day. I am a nameless soup man. I am happy.
Chapter 6: Akira Suwa [Ink on washi / Summer, AD 352] Why was I chosen? The chairman liked my films. I am a film director. Fifty features in 4444. Golden Lion at Venice, while Venice was half-sunk. Theme was always blankness. I brought no camera. Only ink and washi. I landed in northern Kyoto Basin. Late spring. First I lay down and looked at the sky. The sky was blue. In Tokyo in 4444 it was not blue. For the first time at fifty, I saw real blue. I saw twelve women dance in a circle by bonfire—ancestor of kagura, but not yet kagura. Something with no name. I saw a battle from a hill. Two hundred vs three hundred. They looked like ants. The wounded were killed. I wrote: I will not draw battle. Because battle becomes beautiful when drawn. I met a man called KAMUNAGI—one who invites gods. Thirty, already binding four settlements. My final realization: The number of viewers means nothing. The face of the viewer means something. My last film ends here. Cut.
Chapter 7: Shiori Nonomura [Ink on washi / Autumn, AD 360] I was a journalist at the last paper newspaper in 4444. Eight colleagues. Forty thousand readers worldwide. Eccentrics who believed data rots in ten years but paper lasts a hundred. I walked almost the entire archipelago. Over ten million steps. Seventy settlements. I tried to make the first national newspaper of this age alone. I failed. There was no concept of national yet. Writing terrified them. And I got tired. On a small island in the Seto, I found another woman from 4444—Chiaki Yakumo. We spoke in Japanese for the first time in fifty-nine years. She read my tablets and said, What you wrote is historical source material. I will bury this in a cave, in an unglazed jar, so rain cannot get in for four thousand years.
Epilogue: A Single Letter Only Shiori's jar reached 4444. August 17, 4444, 10:32 AM, on the island where Yakumo lived. Inside: tablets, bark paper, and a letter in modern Japanese. --- LETTER --- To everyone in 4444, If anyone is reading this. All seven arrived safely. Ran lived in a marsh in Tohoku, bore a daughter, taught hand-washing. Takeshi served a king in Kinki, loved him. Osamu lived alone in mountains, left tools. A woman brought soup. Chiaki recorded vanishing language on Seto island, taught letters. She is next to me now. Gen taught cooking in Chubu. His dashi spreads. Akira draws in Kyoto Basin. His pictures are treasure. And I walked thirty years. What I wrote is inside. Three things: There was no Nobunaga in this age. Not because there wasn't, but because it's wrong to measure this age with that yardstick. This age is countless small nameless choices piled upon each other. We changed this age. A little, but certainly. Whether it connects to Japan in 4444, we don't know. Whether we changed it or not, we lived it. Living was most important. Most important: Please don't send anyone else. One-way. We knew. We were adults. But no next time. Reasons: One, we are already people of this age. Our children are people of this age. No need for further intrusion. Two, we now think the blank of history may be left blank. True richness lies inside nameless hearts. It cannot be excavated. It cannot be written. Truth is only that it was there. So please remain not understanding. Sometimes not filling the blank is the most accurate way to fill it. We are not heroes. We were seven ordinary people born in 4444, who happened to be in the fourth century. Goodbye. From fourth-century Japan, Autumn, 360. Shiori Nonomura --- End Letter --- Conference lasted three days. Conclusion: Artifact authentic. Letter authentic. But we will not make contents public. Blank may be left blank. That evening, on a dusty desk in the closed transfer room, there was a single white flower. Who placed it is not recorded.
