The only thing I’ll say about Piko-Taro — the character performed by comedian Kosaka Daimaou, who is blowing up right now with his “Pen-Pineapple-Apple-Pen” video — is that my favorite part of the whole thing is the logo and jingle that plays at the start of each of his videos (and then the short “piko” at the end). For more on Piko-Taro, Spoon & Tamago has put up a good post.
