Rilakkuma is a bear-like character created by San-X Co., Ltd. in 2003.

It looks like a bear......but there is a mysterious zipper on its back, and when you pull down the zipper, you can sometimes see a mysterious polka dot fabric.

So, what appears to be a bear is actually a costume. There is also a pocket on the side of the costume, and no one knows what's inside the costume or who is in there. Whether it's deformed, made into goods, or the pattern changes, the zipper is almost always drawn.

Its personality is basically calm......more than that, it's a character that loves to relax. It may rejoice, be surprised, or feel sad when something happens, but it rarely gets angry. It has a calm(?) personality.

It loves to sleep and laze around, and it also loves to watch TV and soak in hot springs.
