Kōbō Kenichi (born August 18, 1973 as Kenichi Mineyama) is a former sumo wrestler from Minamitane, Kagoshima Prefecture, Japan. His highest rank was maegashira 9.
Kōbō made his professional debut in March 1989 at the age of 15. He worked his way quickly through the lowest three divisions, making his makushita debut shortly after his 18th birthday, less than three years into his career. However, he was unable to advance further for several years, reaching sekitori status only in January 1999 upon promotion to the second highest jūryō division, after nearly ten years of toiling in the lower divisions.
He reached the top makuuchi division for the first time in November 2001 but only lasted two tournaments before being demoted. He returned on two other occasions but he largely remained a veteran of the jūryō division, in which he spent 44 tournaments. For a long period he was the highest ranking wrestler in Miyagino stable, before the emergence of Hakuho, now a yokozuna. In July 2007, he fell to the unsalaried makushita division for the first time since September 2000, and he announced his retirement in December of that year.
