This is a list of Ninja Hattori minor characters.
School Students[]
The school students are classmates of Kenichi, Yumeko and Kemumaki. The female ones are friends with Yumeko and Kemumaki. When Kenichi sleep, talks or makes a mistake in his schoolwork, they laugh (sometimes with the exception of Yumeko).
Thieves[]
They are seen in a few episodes, stealing and robbing. In the episode Policeman for a day, Kenichi led a wild - goose chase to catch a thief, and in the end, handcuffed him (along with Shishimaru). They are seen in a few episodes (such as Shishimaru runs away from home) being caught by dogs and being arrested.
Townspeople[]
The townspeople are mostly seen shopping or strolling along the roads. In one episode, a lot of ladies were fighting at the market, though Hattori organised them. In another, a painter was putting signposts on the wall and walked off - Hattori trapped him with his Ninja Stars.
