Born on March 18, 1977 in Hakuba, Nagano, and graduated from Tokyo Denki University.
ZUN got his name from the sound team Zuntata at Taito Corp., the same company that he worked with. Coincidentally, the word 'zun' is a Chinese bronze vessel used to store alcohol. Taito made Darius Gaiden, one of ZUN's favorite shooter games. That's one of the known reasons for him to start the Touhou Project.
