The Hokkaido branch of Japan Post Service Co. will begin selling stamps featuring "Ku-chan," a sea otter that frequents the mouth of the Kushiro River, on March 27.
The stamps are being produced because many people are asking the branch to issue stamps of the otter, which has become a local mascot of sorts, postal officials said.
The widely popular sea otter was spotted by local residents in February and has generated repeated media coverage.
A sheet of 10 ¥80 stamps will cost ¥1,200 and be sold at 68 post offices in and around Kushiro, as well as online via the Japan Post Service.
