In 1997, he debuted with "Japanese Government Maneuver Sqaudron Coumin V". In 1999, his "God's Animal Mountain", won the Chiba Tetsuya Award. In 2004, he began "Moyasimon: Tales of Agriculture" in Kodansha's Weekly Evening magazine, which then brought him a level of fame. After "Moyasimon: Tales of Agriculture" he started his work on "Junketsu no Maria", which became another success.
He is known for drawing fine details in a very thin line, something that he seems to do unconsciously and doesn't use assistants to help him in his work.
The themes and heart are there, but Maria the Virgin Witch doesn’t focus enough on its strengths, which are its characters and not the depictions of war and strife.
