Sadogatake stable
Hasegawa retired in May 1976, but remained in the sumo world as an elder, with the name Hidenoyama Oyakata. Until 2008 he was a Director of the Japan Sumo Association, responsible for the running of the annual "honbasho" held in Nagoya. He then worked at Special Executive level. Unusually for a senior member of the Association, he did not take charge of a stable, instead working as a coach at Sadogatake stable, firstly under former "yokozuna" Kotozakura, and from 2005 under former "sekiwake" Kotonowaka. He reached the mandatory retirement age of 65 in July 2009.
