Jin's seventh published song. It was made for IA PROJECT's compilation album IA/01 -BIRTH-. Nihonbashi is the bridge at the centre of Tokyo. It is the point from which Japanese people measure distances: highway signs that report the distance to Tokyo actually state the number of kilometers to Nihonbashi. The project linked to the bridge is the project to move underground an expressway, obscuring the view of beautiful Mount Fuji from the bridge. This song has entered the Hall of Fame within 24 hours after the upload. The full version of the song is album-only.
