He is an actor, voice actor and narrator. He is currently affiliated with Mausu Promotion. He is a Hanshin Tigers fan. His "Kojirou" alias is not to be confused with [Akito Sakuragi](https://anilist.co/staff/125572)'s alias (they have different kanji at the end).

A swordless “swordsman” and a self-described “schemer” who embark on a quest to obtain twelve peculiar masterpiece blades. Featuring a gatefold color insert, beautiful interior art, and copious bilingual footnotes, this hardcover edition is the first of a quartet scheduled to collect the entire original run. Brimming with action, romance, and unexpected wisdom, often as tongue-in-cheek as The Princess Bride, and shot through with ninjas, samurais, and secret moves, Sword Tale is Musashi for a new generation and a gift for any fan of adventure.
