Arashio stable is a stable of sumo wrestlers, part of the Tokitsukaze ichimon or group of stables. It was set up in June 2002 by former komusubi Ōyutaka, who branched off from Tokitsukaze stable. At the end of 2009 the stable produced its first sekitori, the Chinese born Sōkokurai who in 2013 returned to active sumo after a two-year absence when his dismissal for match-fixing was nullified by the courts. The stable is home to the half-Japanese, half-Filipino wrestler Kōtokuzan. As of January 2023, the stable has 14 wrestlers. The stable's second sekitori, Wakatakakage, reached jūryō in May 2018, and the makuuchi division for the first time in November 2019. In the July 2021 honbasho he became the first wrestler from the stable to reach the rank of komusubi. In the January 2022 honbasho, Wakatakakage became the first wrestler from the stable to reach the rank of sekiwake. Wakatakakage won the March 2022 honbasho.
