For cars, Japan has itasha, which literally means "painmobile". These automobiles are covered in anime, manga and video game imagery. Not everyone in Japan has a car. Many people have bicycles. This post is for them.
At recent otaku gathering Moe Haku 2010, itachari ("paincycle") were on display featuring designs from Namco Bandai's idol simulator game THE iDOLM@STER to fighter plane girl franchise Strike Witches.
