Shinzo Hattori (服部慎造) is the tritagonist of the Ninja Hattori-kun franchise. He is Kanzo Hattori's younger brother.

Physical Appearance Edit

Shinzo is plump, has fair skin, oval-shaped black eyes and rosy cheeks. He often regularly wears red ninja robes, a white belt on his waist and a wooden sword on his back.


Shinzo tricks Hattori into giving him things, annoyingly cries very loudly and disturbs people such as in 'Let's go to the movies', 'Kenichi flies in the sky' and such episodes. However, he's a loyal and devoted brother to Hattori and has a good heart and great compassion. Although he was not too good at the beginning, he has improved and is determined to become a strong ninja.

Shinzo doesn't like people interrupting him when he is talking. This trait was shown in some earlier episodes of the 1981 anime.

Kanzo and Shinzo

Kanzo Hattori Edit

Shinzo looks up to his brother Hattori. He is not as serious as his older brother, but mostly obeys him. They can argue at times though, but they always make amends.

Shishimaru Edit

Shinzo and Shishimaru are inseparable. They often play together and seldom fight, and when they do, their

altercations are mostly playful and end in them making up.

Kenichi and Yumeko Kawai Edit

Kenichi, Hattori's best friend, does mistreat Shinzo sometimes, but still cares for him, and confides in him for help at

times, which can lead to trouble. Yumeko is one of his closest friends, and she often makes him cake and other treats.

Kemumaki and Kagechiyo Edit

Shinzo despises Kemumaki just as much as Hattori does. In "A new ninja technique", he, along with Shishimaru and Kenichi were combatants in the duel between Hattori and Kemumaki. However, Kemumaki did teach Shinzo how to walk on water.

Shinzo also dislikes his cat Kagechiyo, but sometimes they help each other.

The Mitsubas Edit

Shinzo is very close to Mr. and Mrs. Mitsuba, who care for Shinzo like their own.
