- Note: This character's name is derived from Japanese, as no official English name is known.
Atsu-kun (あつくん) is a character from the Tottoko Hamutaro: Hamuchanzu de Gozaimachu! manga series. He is friends with Hamtaro and the other Ham-Hams (who are owned by his grandfather).
Trivia[]
- It is possible that Kazuya O'Hara from the anime series is a grown-up version of Atsu-kun; this would also explain why Atsu-kun had no appearances in the anime, despite Ji-chan still appearing. However, this is completely unconfirmed, and would be somewhat inconsistent with Kazuya's roles in some episodes.
