He retired in September 1996, after more than 15 years in sumo and 1060 consecutive matches. He became an
elder of the
Japan Sumo Association under the name of Kasugayama Oyakata. He re-established the Kasugayama stable in 1997 and coached the Korean-born wrestler
Kasugao to the top division in 2003. Kasugao was one of a number of wrestlers force to retire in 2011 because of a
match-fixing scandal, and as a result his stable lost its only
sekitori. In February 2012 he was elected to the Sumo Association's board of directors, and as a result stood down from the day-to-day running of the stable. He passed control over to the former
Hamanishiki and switched elder names with him, becoming Ikazuchi Oyakata. He was forced to resign from the Sumo Association in September 2012 in a scandal involving a bogus expense claim to cover up an affair with a female employee of the Association. In October 2013 he sued Kasugayama Oyakata (former
maegashira Hamanishiki) for not paying the rent of Kasugayama stable. Kasugayama counter-sued over ex-Kasugafuji's failure to hand over control of the elder stock
(toshiyori-kabu). The case went to trial in July 2014. Kasugafuji's legal team claimed that in 35 years as a coach (from his retirement as an active wrestler at age 30 to his mandatory retirement as a coach at age 65) he would have earned 430 million
yen from the Sumo Association. The two sides settled the stable rent issue in June 2015, with the current Kasugayama agreeing to move to new premises, but Kasugafuji continued to refuse to hand over the
kabu certificate and the ongoing legal dispute led to Hamanishiki being forced to dissolve Kasugayama stable in October 2016 and resign from the Sumo Association altogether in January 2017. The remaining issues were settled in February 2017. ==Fighting style==
