Sang a song as the character Fûma Monô while working on the 'X'
television series in 2001-2002. The song, 'Yakusoku' (or 'Promise' in
English), was also sung by Junichi's co-star Kenichi Suzumura for a
pair of CD singles used to promote the first episode of the series
(which was released on DVD before the rest of the show was aired).
Although the song was not intended for use in the show, it became
popular with fans who bought the CDs anyway.
