He's got a big, goofy grin and a funky headpiece, but one thing the Tokyu train line's newest mascot doesn't have is a name. The little guy's purpose in life is to raise awareness — and "get children excited about" — the Tokyu-Toyoko line's Fukutoshin extension, which is set to open in March of next year.

Word is that he's a playful 10-year-old from Kanagawa Prefecture who is secretly on a diet. (What's that all about? Every yurukyara needs a little bit of a backstory, and this one is a reference to the new trains running on less electricity.) The contest's entry form has spots for writing the name in Japanese or English. The name should be accompanied by an explanation in Japanese. The winning entry, which will become the character's official name, will get a ¥50,000 Tokyu gift certificate. Fifty runners-up will get Tokyu swag. The contest ends on Sept. 28. Think we've got a chance with "Stripey?"
