Tokusegawa Masano (德瀬川 正直, born August 6, 1983, as Badamsambuu Ganbold) is a former sumo wrestler from Ulan Bator, Mongolia.

He was forced to retire by the Japan Sumo Association in 2011 after being found guilty of match-fixing.

His sumo became even more consistent and after a slow but steady rise to the upper ranks of the makushita division, he took the championship in the May 2009 tournament.

Following his retirement Tokusegawa returned to his native country and participated in Mongolian wrestling, winning the Western Region Danshig Naadam tournament in 2012.
