He made his debut in 2001 and has worked as the second incarnation of Marines Mask (マリーンズマスク（2代目）, Marīnzu Masuku (Nidaime)) and as Gabai-jichan (がばいじいちゃん, Gabaijiichan), but achieved most success as Psycho (stylized in all capital letters).

Initially a tweener, his gimmick was that of a deranged wrestler characterized for wearing trashy clothes, sporting a shabby mohawk haircut and talking in an incomprehensible babble.

He remained in AJPW for a time, forming a tag team with comedy wrestler Kikutaro and becoming an unofficial member of Taka's faction RO&D.

He went unnoticed again for the next years, becoming a member of the low-profiled faction Gekirin and gaining a losing effort to Kota Ibushi for the Independent Junior Heavyweight Championship.

Also, at the end of the year Psycho and fellow Gekirin member Saburo Inematsu gained briefly the WEW Tag Team Championship.

In 2011, Marines Mask II appeared in New Japan Pro-Wrestling, losing to Kazuhiro Tamura in the Road To The Super Junior 2 Days Tournament.

Under this gimmick, he wore a bearded mask and carried a walking cane, simulating to be an elderly wrestler who fell down with the smallest hit, and relegated himself to comedy matches.
