Source-derived summary

Showtaro Morikubo (森久保 祥太郎, Morikubo Shōtarō; born February 25, 1974) is a Japanese voice actor and singer who has voiced characters in anime, drama CDs, and video games. He was formerly affiliated with I'm Enterprise, Sigma Seven and VIMS. His most notable roles were Shikamaru Nara from Naruto, Souji Okita in the Hakuouki series, X in the Mega Man X series, Yuusuke Makishima from Yowamushi Pedal, and Yosuke Hanamura from Persona 4.

Biography

Morikubo graduated from Third Junior & Senior High School of Nihon University in 1992, and dropped out of Tama Art University. Before becoming a full-fledged voice actor, he worked at a talent agency, and was recruited by people in the voice acting industry who saw a performance by the Onigiri Skippers, a theater troupe he founded with his seniors from the lab party he attended in elementary school. During his first dubbing session, he made sounds out of flipping pages on the script because he had no experience as a voice actor at that time. The script for the first episode had four pages of long dialogues from the first page, and the sound director said that he would never have let him do the role if he had known he would talk so much. He made his voice acting debut in 1996 as a Mini 4 Fighter in Bakusō Kyōdai Let's & Go!!. The show was supposed to finish in a year, but due to its unexpected popularity, it became a long-running production, and he moved from the agency where he had worked as an actor to a voice acting agency. Since then, he has been active in a variety of fields including animation, games, radio personality, music, and stage.

After working at Sigma Seven, Morikubo moved to VIMS, an office affiliated with Arts Vision.

Editorial summary

Begin with the source’s own compact description: “Showtaro Morikubo” is japanese voice actor. The dossier treats that line as a proposition to test through Showtaro, Morikubo and Japanese, not as a finished interpretation.

Editorial reviewA productive starting point for separating a subject’s documented career from later reputation and commemoration. The current lead gives the account dated anchors—1974, 1992, 1996—that can be checked directly. The linked authority record independently contributes the date 1974-02-25. For this dossier, Showtaro, Morikubo and Japanese is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “japanese voice actor” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

The entry’s evidential value lies in the named roles, institutions and publications that can be tested against primary documentation. The source revision retrieved here is dated Sep 18, 2026. The linked authority identifier is Q1352553. VIAF identifies the subject as 296790758. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1974, 1992 and 1996.

Critical limits

Public reputation and documentary evidence do not always develop together; absence from a summary is not evidence of historical absence. 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.

How to read it
