There are a lot of cute anime character or mascot of products or baseball team. I recently like ゆるキャラ "yuru chara". Yuru chara is abbreviation of Yurui Character and new Japanese word.
A adjective original "Yurui" ゆるい means loose, gradual, slow, or easygoing. This meaning of "Yurui" for "yuru chara" is strange, unique and crude, but cute and funny. (It is very difficult to explain in English! )
Yuru chara is mainly a mascot to introduce the prefecture, city, place or event.
For example, "Hyikonyan" ひこにゃん is a mascot of Hikoneshi 彦根市 in Shiga prefecture. Sento-kun せんとくん is a mascot of ancient city, Nara prefecture. I didn't know how many kinds of Yuru chara, however, so many mascots in Japan.
My favorite mascots are Oshinari-kun おしなりくん and Tomapi トマピー. And I found a funny mascot, nashite-kun ナシテ君. It is a mascot of a local TV station in Niigata prefecture. You might find your favorite mascot in site of yuru chara. ↓
