Tetsuya Miyamoto

My name is Tetsuya Miyamoto. I am the inventor of KenKen. It's in The New York Times every day! After I worked at SapiX, in 1993, I set up Miyamoto Sansu Kyoshitu (mathematics cram school) in Yokohama. In 2009, I wanted to have mathematics class in the center of Japan so I moved it to the place of a three minute walking distance from the Nihonbashi exit of Tokyo station. In 2015, I wanted to have mathematics class in the center of the world. So I moved my cram school to the place of a ten minute walking distance from Grand central station in Manhattan,NY. http://www.miyamoto-mathematics.com/
