The special shinkansen, or bullet train, will be decked out with the mouthless character that has morphed into a multi-billion-dollar industry since its introduction by Sanrio in 1974.

The Hello Kitty branding features cover the outside and interior of the train, covering its seats, floors and windows.

The aim is to revitalize regional communities in western Japan, the railway said. And the country's tourism industry is also looking for a boost from the world famous cartoon character, which has spread around the globe since its creation by Yuko Shimizu more than four decades ago.
