Kappabashi-dori, also known just as Kappabashi or Kitchen Town, is a street in Tokyo between Ueno and Asakusa which is almost entirely populated with shops supplying the restaurant trade. These shops sell everything from knives and other kitchen utensils, mass-produced crockery, restaurant furniture, ovens, and decorations, through to esoteric items such as the plastic display food ( sampuru, derived from English sample) found outside Japanese restaurants.
The street is also an off-beat tourist destination.
The street's name is believed to come from either the kappa (raincoats) of nearby residents which were hung out to dry on the bridge, or from a merchant named Kihachi Kappaya who funded the project to build Shinhorikawa River for water management. However, due to the homophone with the popular mythical creature, Kappa, the shops along the street have officially adopted the kappa as their mascot. Images of kappa appear frequently in the area, from merchandise to displays, even web sites about the district.
