Sadogatake stable (佐渡ヶ嶽部屋, Sadogatake-beya) is a stable of sumo wrestlers, one of the Nishonoseki group of stables. In its modern form, it dates from September 1955, when it was set up by former komusubi Kotonishiki Noboru. Former yokozuna Kotozakura took over the running of the stable in 1974 following Kotonishiki's death. The stable is located in Matsudo, Chiba prefecture. Over the next thirty years the stable produced a string of top division wrestlers. Kotozakura stood down in November 2005, handing the stable over to his son-in-law, former sekiwake Kotonowaka.
Between September 2007 and July 2010, it became the first stable since Musashigawa stable in 2001 to have two wrestlers ranked at ōzeki simultaneously, with Kotomitsuki and Kotoōshū. It happened again between November 2011 and November 2013 with Kotoōshū and Kotoshōgiku. As of January 2023 the stable has 26 wrestlers, three of them being sekitori. In March 2020 Sadogatake-oyakata's son, who also goes by the name of Kotonowaka, reached the top makuuchi division. On the May 2020 banzuke all five sekitori were ranked in the top division, although none were above maegashira 13. The most the stable has ever had in makuuchi simultaneously is seven, in November 1992 and January 1993.
A successful stable, Sadogatake is currently the active stable with the longest continuous presence (59 years) of at least one of its wrestlers in the makuuchi division.
