He has taken over ongoing roles for voice actors Shigezō Sasaoka, Eiji Kanie, Shinji Nakae, Daisuke Gōri and Hirotaka Suzuoki after their deaths. A number of his foreign film-dubbing roles are occupied by Tesshō Genda in different editions of those films.

Why this record matters
The subject matters to the people & ideas register because the source frames it as japanese actor, voice actor and narrator. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Chronology provides the most reliable spine for this subject; interpretation should follow only after identities and dates are secure. The source revision retrieved here is dated Sep 6, 2026. The linked authority identifier is Q1209737. VIAF identifies the subject as 221047432. The Library of Congress control number is n2011088635. 2 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
A concise life account rarely captures disputed attribution, private networks or the changing language used to describe a career. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
