“Rilakkuma” means “Bear in relaxed mood”. At all time and everywhere he goes he is always lazy and relaxed.

Rilakkuma mysteriously appears in the female office lady Kaoru's apartment one day. He is a soft toy bear who has apparently decided to take up residence there. On his back is a zipper which when opened reveals a light blue polka dot patterned material. The reason for the zipper on his back is unknown.
