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.[1]

The name corresponds to the fact that video and text are not directly linked, encouraging viewer's imagination. In an interview with Takuya Mitomi and Takuya Hosogane, the producer revealed that after being asked to direct the animation he considered various approaches for how the video should look like. In the end he went with the concept of imitating an experience one would feel while browsing tumblr, with all of the cuts being created with animated GIF's in mind, each of them telling a random story.[2]

This song has entered the Hall of Fame within 24 hours after the upload.

The full version of the song is album-only.

愛なんて信じちゃいけないよ? ai nante shinjicha ikenai yo?
その雰囲気(ムード)はちょっとダサいね sono muudo wa chotto dasai ne

濁っちゃった空気は知らないよ nigocchatta kuuki wa shiranai yo
無視してさ、進もう mushishite sa, susumou

白線を踏み外さないように未来へ hakusen o fumihazusanai you ni mirai e

振り向いて、忘れないように右へ倣った furimuite, wasurenai yō ni migi e naratta

自動車も自販機もいないのかい? jidousha mo jihanki mo inai no kai?
