Ōnobori Mitsuhiro

He joined Kasugayama stable in 1941, recruited by the 14th Kasugayama Oyakata, ex-sekiwake Fujinokawa. However the stable shut down in 1947 and he was transferred to Tatsunami stable. In 1955 the stable was revived by ex-ozeki Nayoroiwa and he once again became a member of Kasugayama stable. He reached the top makuuchi division in 1951 and in just his second tournament in the division he had his greatest success, finishing runner-up to Chiyonoyama in May 1951 with a 12–3 record and winning the Fighting Spirit prize. In January 1955 he defeated yokozuna Tochinishiki to earn his only kinboshi, or gold star. Although he scored ten wins against five losses from maegashira 5 in this tournament, there was no sanyaku position open for him and he was ranked at maegashira 1 on the banzuke in the following tournament in March 1955. He scored only two wins against thirteen losses, and this was to be his highest rank. After 21 top division tournaments he was demoted to the juryo division after the May 1956 tournament. He did not compete on the dohyo again, officially retiring in January 1957.

Onobori remained in sumo as an elder of the Japan Sumo Association, working as a coach at his old stable under a variety of elder names. In January 1971 he became head coach of Kasugayama stable following the death of ex-Nayoroiwa. He raised Kasugafuji, who also reached the rank of maegashira 1. Onobori was a director of the Sumo Association for four years from 1982, and an auditor from 1986. One of his nieces married Asahifuji in 1988. He reached the mandatory retirement age of 65 in 1990, and Kasugayama stable was wound up and absorbed into Ajigawa stable (although it was later revived by Kasugafuji upon his own retirement). Onobori died in Tokyo in March 2009 at the age of 83, from pneumonia.[1]
