Dewanoumi stable
Oginohana remained in the sumo world as a coach at Dewanoumi stable and an elder of the Japan Sumo Association. For two years after his retirement he had "jun-tosiyori" status and used his old fighting name (a practice since abolished), but in 2000 he became Takasaki-"oyakata", succeeding his father who had reached the mandatory retirement age for coaches of 65 years old. In February 2014 he became the head coach of Dewanoumi stable, succeeding former "sekiwake" Washūyama who was also nearing retirement age. He is also a judge of tournament bouts and has deputized for chief judges Kasugano and Fujishima. In January 2016 he was elected to the Sumo Association's board of directors.
