Tomohiro Nishimura

Tomohiro Nishimura was born in 1961 in Asahikawa, Hokkaido, Japan.

His real and former stage name is also Tomohiro Nishimura.

As a child, his nickname "Omo" came from his mispronunciation of "Tomo-chan" (derived from his real name Tomohiro).

His blood type is O.

He moved to Tokyo after failing college entrance exams, determined to become a musician.

Interested in singing, he initially pursued a career as a singer-songwriter and performed live mainly in Kanto.

To make a living in Tokyo, he started doing voice acting and debuted as Chibi in "Urusei Yatsura."

He soon found his calling in voice acting, though he was replaced in his debut role due to lack of experience.

He continued in the anime as a different character, Kotatsu Neko, which required non-verbal acting—a challenge he found tough yet rewarding.

His cheerful, slightly husky voice made him a popular choice for comedic, quirky, or three-dimensional supporting characters.

Nishimura built strong ties with peers, notably with veteran voice actor Shigeru Chiba, whom he considers a mentor.

He was also close with fellow voice actress TARAKO, forming a deep friendship since their early band days.

He became active as a radio personality, mainly on Radio Nikkei and collaborating with stars like Megumi Hayashibara and Manami Komori.

He was known as "Omo" on air, a nickname rooted in his childhood.

Previously, he was affiliated with Troubadour Music Office, Ken Production, and 81 Produce, but eventually went freelance.

In 2003, he founded his own company "OMO Inc." and branched out as a sound director for video games, OVAs, and drama CDs.

Nishimura's anime roles span decades and genres, including Chibi and Kotatsu Neko in "Urusei Yatsura," Shuu in "Yoroiden Samurai Troopers," Gigil in "Macross 7," IR in "Collector Yui," and tens of memorable guest and supporting roles.

He worked on many theatrical animations, OVAs, games, and dubbing foreign films and series, with notable appearances as voices for beloved international characters such as Butch in "Tom and Jerry."

Besides anime, Nishimura has been active in stage production—writing, directing, and acting.

He contributed to famous radio dramas, performed music for anime and games, and composed songs for his own and others' works.

There are no widely recognized mainstream awards listed for Tomohiro Nishimura, but he is regarded as a versatile and respected veteran in the Japanese voice acting and entertainment scene.

He has been recognized for his multi-faceted contributions—both as a performer and as a director.

He considers veteran voice actor Shigeru Chiba as his mentor since their work on "Urusei Yatsura."

He maintains a strong friendship with fellow voice actress TARAKO, describing their relationship as open and comfortable, akin to that of close male friends.

Nishimura’s nickname "Omo" is rooted in his early childhood, where he mispronounced his own name.

He is known for his approachable and friendly demeanor, both on-air and off.

He has been largely private about his family and marital status.

• His voice is often described as slightly raspy and cool, perfect for lively or comedic characters.
