Sirotan
"Sirotan" is a Japanese merchandise character created by Creative Yoko. Sirotan is a young harp seal, white in colour but often disguised as other cute animals and objects. He was born on August 8, in Northern Iceland. Sirotan's favorite things to do are napping and swimming in the ocean. He loves dressing up and playing. "Sirotan" literally means, "Widdle White," the childish version of "Little White."
The first theme shop that is dedicated to Sirotan is currently found at Haneda International Airport.
