One of the six new characters who will bear the future of San-X!
What kind of character is Mainichi Hamuchima, who debuted in October 2025?

Mainichi Hamuchima, who debuted this time, is a hamster character born as one of the six new characters who will bear the future of San-X, in the ‘San-X no Ko Project’ carried out in September 2024! What kind of character is it, you ask?

“Anyone who has worked hard as an adult should be able to relate.”
There are times when you feel down in your everyday life, right?
Hamuchima feels the same way.

The little joys that can be found precisely because of such a daily life = Chima Happys.
May you too find little joys together with Hamuchima.
And may your little joy = Chima Happys become Hamuchima.

Hamuchima, a tiny hamster, finds ‘little joys’ with friends even while struggling with various things every day. Seeing that gives us energy and encouragement...... it’s a very small friend who walks through every day with you!

Cute merchandise for Hamuchima is being released one after another! If any of you feel a little tired...... please take a look at this Hamuchima merchandise, who is working hard alongside you, and get a boost of energy!
