Yūta Mochizuki

Yūta Mochizuki (望月 祐多) played Kouji Segawa, the titular rider of the stand-alone movie, Kamen Rider J (1994). He reprised his role only in voice that same year in the short 3-D film, Kamen Rider World, which served as a crossover with Kamen Rider ZO.

Despite J going on to make later minor appearances, including in recent crossover movies, Yūta Mochizuki has yet to reprise his role again.

Yūta Mochizuki is also known for playing Yamato Tribe Prince Geki/TyrannoRanger in the Super Sentai series, Kyoryu Sentai Zyuranger. This makes him, as of 2012, the second actor to have played a Sentai Ranger and protagonist Lead Kamen Rider, after Hiroshi Miyauchi, and the only actor to have played both a Sentai Red and a protagonist Lead Kamen Rider. Another other Red actor who came close is Keiichi Wada who played a minor character who became the titular rider of Kamen Rider Ryuki. However, for him to have shared Yūta Mochizuki's distinction, he would have had to have played the main protagonist of the series. Hidenori Tokuyama also played a rider, but he was not the leading rider of his series.
