He hasn't done much work outside of the Naruto series. His earlier work, Karakuri, and his one-shots Bench! and Mario. He did the guest character design for Lars for Tekken, of course, and he recently illustrated two covers for Shueisha's upcoming Japanese history manga collection. In 2012 he illustrated a cover for an issue of the Japanese newspaper The Future Times. Beyond that he's done collaboration illustrations with Akira Toriyama (Dragon Ball), Hiroaki Samura (Blade of the Immortal), and his brother Seishi Kishimoto (Sukedachi Nine), and a few special tribute illustrations for other manga, including Dragon Ball, Jojo's Bizarre Adventure, Kingdom, Bleach, Levius/est, and My Hero Academia.

There may be some other things, but that's all I've found.
