On television, Kitaōji portrayed Miyamoto Musashi in the Nippon Television show of the same name. A major historical role was Sakamoto Ryōma in the year-long prime-time NHK Taiga drama Ryōma ga Yuku (1968). 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. Kin'ya returned to NHK for the 1987 Taiga drama Dokuganryū Masamune as Date Terumune, father of title character Date Masamune.

Another role he took had been created by his father. Saotome Mondonosuke was the title character in the series Gozonji! Hatamoto Taikutsu Otoko. It ran from 1988 to 1994 on TV Asahi. His father, Ichikawa Utaemon, had appeared in numerous films as Mondonosuke.
