, formerly known as Irumagawa stable from 1993 to 2023, is a stable of sumo wrestlers, part of the Dewanoumi or group of stables. It was set up in January 1993 by former Tochitsukasa, who branched off from Kasugano stable. The first 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 ( 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 (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, , hence being the only in his stable and the first Ukrainian to do so. Shishi became the present stable's first top-division wrestler upon his promotion to in November 2024.
In December 2024 stablemaster Ikazuchi announced that the stable would be moving from Saitama city to the Sumida ward building that was recently vacated by Ōshima stable. The move is planned to take place in February 2025.
