Taishi, under the name/ circle C.O.A.D, began releasing music in 2002, publishing self-produced MIDI works on his website. He eventually launched his own doujin circle "Compllege" in 2005 (becoming the parent to C.O.A.D), moving to a new domain and has since continued to release songs and CDs as apart of Compllege. He has also appeared in various other doujin circles as a guest producing compositions and arrangements, and continues to do so to this day.

Taishi began other activities in 2007, such as starting another doujin circle, Allium Project, which focused on producing VOCALOID songs. It was also around this time Taishi began participating in the soundtracks for various visual novel games.

Near the end of 2007, Taishi joined Akihito Ito's Blasterhead unit, remaining a member until Ito's disappearance in 2013.

He also had many commercial album releases under both the Electro.muster and TRäkker units for the labels Cosmic Record and GWAVE between 2011 to 2015, also producing the majority of the Ongaku Shoujo songs, including remixes for 2018 anime adapation.

He is also a member of the wavforme doujin label, and a member alongside Nhato of the hardstyle unit Edelritter. He has also been appearing as a DJ in many Tokyo based events.

He joined the Arte Refact unit in July of 2020 as a composer & arranger.
