Asōfuji Seiya (born January 17, 1976, as Kiyotoshi Suginomori) is a retired sumo wrestler from Fukaura, Nishitsugaru, Aomori, Japan.

He joined Ajigawa stable, run by former yokozuna Asahifuji, who was also of Nishitsugaru District and a cousin of Asōfuji's father.

In that tournament, there were three sets of brothers (Asofuji and Aminishiki, Kitazakura and Toyozakura, and Rohō and Hakurozan) in the top division simultaneously for the first and only time in sumo history.

He managed a 5-2 score in the March 2008 tournament which returned him immediately to the second division, but again he was unable to secure kachi-koshi (more wins than losses) and was demoted to makushita once more.

Asōfuji was one of 23 wrestlers found guilty of fixing the result of bouts after an investigation by the Japan Sumo Association, and ordered to retire in April 2011.
