He landed the title role in the long-running cop show Zenigata Heiji, set in the Edo period. In the 1985 twelve-hour New Year special Fūun Yagyū Bugeichō, he played Yagyū Jūbei, and in the following year's special, he portrayed both Tokugawa Yoshimune and Yagyū Shinrokurō. The role of another shogun fell to him in the following new year as TV Tokyo tapped him to play Tokugawa Iemitsu.
