, formerly known as Irumagawa stable from 1993 to 2023, is a stable of sumo wrestlers, part of the Dewanoumi ichimon or group of stables. It was set up in January 1993 by former sekiwake Tochitsukasa, who branched off from Kasugano stable. The first sekitori produced by the stable was (also known as Shirasaki) in January 1994. As of February 2023 it had seven wrestlers.
History
On 26 January 2023 it was announced that Irumagawa, in anticipation of his mandatory retirement in April, would give control of his stable to coach Ikazuchi (former komusubi Kakizoe) without him inheriting the Irumagawa elder name. The stable name change took effect six days later on 1 February, creating the first incarnation of the Ikazuchi stable in 62 years. In addition, the board meeting of the Japan Sumo Association approved the transfer of coach Wakafuji (former Ōtsukasa) to Kise stable the following month.
In 2020, the stable recruited Ukrainian Serhii Sokolovskyi who made his debut during the March tournament under the name Shishi. This professional debut made Ukraine the 24th foreign country or territory to have a wrestler join professional sumo. In May 2023, Shishi reached sumo's second highest division, jūryō, hence being the only sekitori in his stable and the first Ukrainian to do so.
Ring name conventions
Many wrestlers at this stable take ring names or shikona that end with the character 司 (read: tsukasa), meaning boss, in deference to former coach and stable owner, the former Tochitsukasa.
