03 / PROFILE

Profile

Dedicate one's entire life to game development.

Born in 1981 deep in the mountains of Yamaguchi, Japan. As a child, tree climbing was the greatest entertainment.

That changed the moment he encountered Super Mario Bros. on the Famicom. From there, he set his sights on becoming a game creator and began making games on his own in elementary school.

After graduating from a vocational school, he joined a game company as a graphic designer. After spending 10 years making games as an employee, he became independent and returned to making games on his own.

Achieved a cumulative total of 10 million downloads for self-developed games within five years of going independent. Today, he runs his own company while supporting people who want to become game creators.
