Oyasumi Hologram Produced by Koichi Ogawa, who writes and composes all of the bands songs, the group began performing in May 2014 and released their first album, Oyasumi Hologram, in September 2015. Since then, they have released a total of five original albums, followed by a greatest hits album, 1, in 2019. In terms of live performances, they sold out their first solo concert at Shinjuku LOFT in 2015. They have also actively participated in solo concerts and events at venues such as Shibuya O-WEST, Shibuya WWW, and Ebisu LOQUIDROOM, and in 2019, they embarked on two nationwide tours, continuing to expand their activities. In October 2020, member Hachigatsu-chan left the group. After a period as a five-member unit called OYSM5, the group is currently active as Oyasumi Hologram (a PC and guitar-based duo featuring Kanamil and Ogawa) and as the Oyasumi Hologram Band Set (a full band lineup). On November 12, 2025, at Shinjuku Loft, the duo unit Oyasumi Hologram THE ORIGIN, featuring Kanamil and former member Hachigatsu-chan, was launched. Even as their lineup has changed, the unique worldview created by Oyasumi Hologram continues to attract attention not only from idol fans but also from musicians and creators.
