Born in Arikawa, Minamimatsuura District, he made his professional debut in January 1956, and reached sekitori status four years later upon promotion to the jūryō division in March 1960. He made his top makuuchi division debut in January 1961. Sadanoyama won his first tournament title in only his third tournament in the top division, from the rank of maegashira 13. The achievement of winning a tournament from the maegashira ranks is sometimes seen as a jinx on subsequent success in sumo, but Sadanoyama disproved that theory by going on to reach ōzeki in March 1962 after winning his second title, and then yokozuna in January 1965 after capturing his third championship. monument He made a cameo appearance in the 1967 James Bond filmYou Only Live Twice, as himself. Although more attention was focused on yokozunaTaihō and Kashiwado, with their rivalry referred to as the Hakuho era after a combination of their shikona, Sadanoyama in fact ended up winning more tournament championships than Kashiwado. Sadanoyama announced his retirement suddenly in March 1968, despite having won the previous two tournaments, two days after a surprise loss to a new maegashira, the Hawaiian born Takamiyama. It has been suggested that the shock of losing to a foreigner may have prompted a premature retirement.
Retirement from sumo
Sadanoyama remained in the sumo world after his retirement, as an elder. Having married the daughter of the previous stable boss, former maegashiraDewanohana Kuniichi, he became head coach of the Dewanoumi stable. One of the most powerful heya in sumo, he produced a string of top division wrestlers, including Mienoumi, Dewanohana Yoshitaka, Washūyama, Ōnishiki, Ryōgoku, Oginishiki and Mainoumi. In February 1992 he became head of the Japan Sumo Association. He was chosen ahead of his contemporaries Taihō and Kashiwado partly because he was in better health than either of them. He changed his toshiyori name to Sakaigawa in 1996, handing over the Dewanoumi name and the day-to-day running of his stable to the former Washūyama. He did not run for re-election in 1998, after it became clear he lacked enough support, and was replaced by former ōzekiYutakayama from the rival Tokitsukaze faction. He subsequently became head of the judging department, an unusual move for a former head of the Sumo Association. He stood down as an elder in 2003 upon reaching the mandatory retirement age of sixty five.
Sadanoyama was known for employing pushing and thrusting techniques such as tsuppari and regularly won by such kimarite as oshi dashi and tsuki dashi. However he was also good on the mawashi where he preferred a migi-yotsu grip, and often won by yori kiri and uwatenage.
Career record
The Kyushu tournament was first held in 1957, and the Nagoya tournament in 1958.
