Futagodake Takeshi was a Japanese sumo wrestler and stablemaster whose career stretched from the early 1960s into the first decade of the twenty-first century. Born Takeshi Yamanaka on 15 November 1943 in Kanagi, Aomori Prefecture (now part of Goshogawara), he entered professional sumo in January 1961 and rose to the top division as a technical wrestler remembered for left-hand grips, shitatenage (underarm throws) and the rare uchi-musso and soto-musso twists. He reached the rank of komusubi, won a Technique prize, earned a kinboshi victory over yokozuna Taiho, and later founded Araiso stable. He died of hepatocellular carcinoma on 10 September 2026, aged 82. The Japan Sumo Association announced his death on 13 September.
As a junior-high sumo club member he was recruited after a teacher, asked by yokozuna Wakanohana I to find apprentices, brought him to Hanakago stable. When Wakanohana retired and took the elder name Futagoyama, Yamanaka followed him into the new Futagoyama stable. He was promoted to juryo in November 1964 as that stable's first sekitori, though a fracture sent him back to makushita. After returning to juryo in 1966 he changed his shikona from Wakafutago to Futagodake and reached makuuchi in January 1967. Light for a top-division wrestler, he built a repertoire of throws and twists rather than brute force, and coaches of the era later credited him with helping make uchi-musso and soto-musso familiar techniques rather than curiosities.
His peak years brought three komusubi appearances, a 10-win Technique prize in November 1968, and a kinboshi against Taiho in November 1969. In September 1974, wrestling as a maegashira against future yokozuna Mienoumi, their bout was declared a draw after repeated water breaks and a rematch produced no decisive result. It was the first makuuchi draw since 1963 and remains the last such draw recorded in the top division. Across 94 career tournaments he compiled a near-even record and spent 57 tournaments in makuuchi before retiring in September 1976.
He stayed in the Japan Sumo Association as an elder, first as Shiratama and later as Araiso. In May 1993 he branched from Futagoyama and opened Araiso stable in Kunitachi, Tokyo. The stable closed when he reached the mandatory retirement age of 65 during the November 2008 tournament; two of his three remaining wrestlers retired with the stable, one moved to Hanakago, and Futagodake himself finished his tenure attached to Matsugane stable. None of his wrestlers reached sekitori while he was master, but his former apprentice Arawashi later reached juryo and makuuchi after the stable closed, and Futagodake took part in Arawashi's danpatsu-shiki and stayed in touch with him into the 2020s.
Japanese and English reports of his death cite hepatocellular carcinoma and the Sumo Association's 13 September announcement. Nikkan Sports, Jiji Press and other outlets memorialised the Aomori-born komusubi whose soft personal manner, peers once joked, may have kept him from an even higher peak, and whose technical curiosity left a lasting mark on how sumo techniques are taught and named.

Didn't know he trained Arawashi. Small stable, real legacy though.
