3470.mon (pronounced Sayonara Monday) is a visual kei solo project from Tokyo that has been active since the summer of 2020. The project is part of the art kei subgenre. Initially, the project was called Sugoi Hitotachi (Kari) (凄い人達(仮)), but in 2021, the name was officially changed to 3470.mon. The project is fronted by vocalist Tenten (平一洋, Taira Kazuhiro) (former member of My BACTERIA HEAT IsLAND), along with RENA on bass (from CRAZY PUNK KID) and SYUTO on keyboards (from LAID BACK OCEAN), with support members like guitarist Satoshi (サトシ) from Initial'L, guitarist KAI (カイ) from CHAQLA., support drummers Chargeeeeee..., CHARLIE (チャーリー), Hyuga, Shuu and Sho (匠-SHO-).

The project began with the release of four music cards (known as “M∞CARD”) between late 2020 and mid-2021. These releases were titled “Jyunketsu-san” (純潔さん), “Supiido ihan-san” (スピード違反さん), “Genkaku-san” (幻覚さん), and “Yofukashi-san” (夜更かしさん).

The official announcement of the project under its new name came in the spring of 2021, when RENA and SYUTO joined the lineup. Their first major oneman live, titled Devil’s Transfer Student, took place on July 18, 2021, at WILDSIDETOKYO. This marked the full-scale launch of the project, followed by the release of their debut EP VHS on August 2, 2021.

3470.mon quickly gained attention, with VHS reaching the top of the iTunes Store Daily Rock Ranking, showcasing their unique presence in the visual kei scene. The music of 3470.mon blends elements of R&B and soul, with an unconventional fusion of punk intensity and softer melodic styles. Read more on Last.fm.
