More fun from Japan: welcome the Hotaru-san!

The same crazy guys who brought you Vending Machine Red and friends, and later the Limon guy from Sprite and his journey across Japan, are now invading unsuspecting communities in Tokyo with a horde of dancers with yellow lights on their butts. It looks like a silly flash mob but they're FIREFLIES (Hotaru-san) and they are advertising a new service from Japanese Internet Service Provider So-Net. Very cute, very Cirque du Soleil. This is going to go viral worldwide.
