ハイスクール!奇面組
When he was a college student, Kanemaru was working part-time at the Far East Network in Yokota Air Base. At the same time, he was recruited while working as a studio DJ at a department store in Shinjuku, and a few days later he participated in the dubbing session for "Urusei Yatsura". After that, he took part in several of Fuji TV's Saturday evening shows such as "High School! Kimengumi", "Tsuide ni Tonchinkan", and "Meimon! Dai San Yakyūbu". At the time, he was employed by Beniya 25-Ji and Dojinsha Production. He got his first lead role in 1991's "Future GPX Cyber Formula", where he played Hayato Kazami. He found out about it the day before the recording, when he heard an answering machine on his trip, and rushed home to read the script on the day of the recording. When he appeared in "Cyber Formula", he was also teaching at an eikaiwa school, and one of his students' parents leaked information about him, causing a huge commotion in the adjacent shopping district as anime fans rushed to the place where he was teaching.
