President and CEO of Koto from 2001.


Koto Co., Ltd. was established in 1996 by GUNPEI YOKOI, a leading game developer in NINTENDO until 1996. He put out a variety of home-entertainment Nintendo products e.g. "Ultra Hand", "Love Tester", "Light Ray Gun SP", "Tenbillion", "Game Watch" and "GAME BOY", ranging from analogue to digital products.
Change adversity to fun just by adding a touch of entertainment here and there, has been the goal of Koto since its establishment. Wouldn’t it be a lot more fun and encouraging if a maze game could be incorporated into a walking rehabilitation device? Gunpei Yokoi (deceased) had had all sorts of delighting ideas of the kind and this DNA is totally inherited now without fail.  
We believe enjoying our everyday work is the best approach to create amusing products and that is we put up our company motto as "Enjoy your job", making a more fun environment for more fun work.
