(51) This time I would like to introduce...
宮崎県西都市にある西都原古墳群13号墳
Saitobaru Kofun Tumulus Group No. 13 in Saitobaru City, Miyazaki Prefecture.
今回ご紹介する13号墳は、数ある有名な古墳の中でも、
西都市の観光案内表紙に乗っているくらいかっこいいのです。
Tumulus 13, which I'll introduce here, is one of the many famous tombs, and it's so cool that it's on the cover of the tourist information sash of Saito City.
ボランティア案内所でもらった「探訪ガイドマップ」を片手に
折り畳み自転車で出発
We set off on our folding bicycles, with the "guide map" given to us at the volunteer information center in hand.
この古墳群は広大なエリアに無数の古墳が点在しているため
マップがないと迷ってしまうくらいなのだ。
The Kofun tumulus group is a vast area dotted with countless tumuli, so without a map, it is easy to get lost.
枯草のなかの道を走っていくと木々の間にその美しい姿を現す。
As we drove along the road through the dry grass,
its beautiful shape appeared among the trees.
きわめて特徴的な墳形
A very distinctive mound shape
柄鏡型前方後円墳だ！
It's a tortoise-shell mirror-shaped anterior-posterior mound!
同古墳群に属する古墳の中でも、最古級の一つ。
It is one of the oldest of the tumuli in this tomb group.
後円部墳頂から前方部を望む。その先に1号墳が見える
後円部の高さに比べ前方部は低く長いのが特徴
It is one of the oldest among the tumuli in this tomb group, and is characterized by the fact that the front part is lower and longer than the height of the back part.
墳丘は築造当時の形に復元されている。
The mound has been restored to the shape it had when it was built.
後円・前方ともに3段築成で、段は連続している
Both the posterior and anterior sections are built in three stages, and the stages are continuous.
長さ79.4 m、後円部の直径43.2ｍ、高さ7.2ｍ、
前方部の長さ38.6ｍ、幅25ｍ
The length of the mound is 79.4 m, the diameter of the posterior part is 43.2 m, the height is 7.2 m, and the length of the anterior part is 38.4 m.
The anterior part is 38.6m long and 25m wide.

また埋葬施設の内部は公開されている
The interior of the burial facility is open to the public.
後円部の階段を登っていくと入口がある

中は築造状態の湿度が保たれ、長さ8.1mの粘土槨が見学できる。

and you can see the clay burial chamber of 8.1m in length.
また墳丘の地層断面から版築の様子も見学できる。
The burial chamber is 8.1m long and you can see the burial chamber
from the stratum of the mound.
墳丘は粘土質の上に透水質の層を作ることで、
水が古墳の内部に入りにくくし、粘土槨や墳丘を守る
キャリパリーバリアを1500年間にすでに見出していたということだろう。
The burial chamber is made of clay with a permeable layer to prevent water from entering the burial chamber and the mound.
出土物は、三角縁神獣鏡1面、翡翠製勾玉２点、碧玉製管玉40点余り、
ガラス製小玉多数、鉄剣、刀子、棺材と思われる木片等
The excavated artifacts include a triangular-rimmed mirror, two jade beads, more than 40 jade beads, many small glass beads, an iron sword, a sword, and a piece of wood thought to be coffin material.
