The Sumida River flows through the center of Tokyo. The Tokyo Hotaru Festival was created with the desire of bringing fireflies to Tokyo and allowing residents to coexist with nature.
“A symphony of lights created by the river and trees”
About 100,000 LED lights that store solar electricity – called “Inoriboshi®” (“Prayer Stars”), are being released into the Sumida River to make Tokyo into a beautiful city.
“Prayer Stars” started being released!
They are carried downstream, and the river is getting illuminated.
Amazinglly beautiful! (Real ones are much more beautiful!)
Enjoy watching video!
Illuminated Tokyo Sky Tree in indigo blue, which is one of the Japanese traditional colors, and is also of the Sumida River!
How fantastic and romantic!
The real tower is much more beautiful, and will be open to the public soon on May 22!
LED lights are collected downsteam and will be reused to be environmentally friendly.
