Sakaigawa stable (境川部屋 Sakaigawa-beya) is a stable of sumo wrestlers, part of the Dewanoumi group of stables. It was established in its modern form on 25 May 1998 by former komusubi Ryōgoku, who branched off from Dewanoumi stable. It was originally called Nakadachi stable, but when Sakaigawa Oyakata (the 50th Yokozuna Sadanoyama) reached the Japan Sumo Association's mandatory retirement age in February 2003, he passed on the Sakaigawa name, and the stable was renamed. As of January 2016, it had twenty three wrestlers, with five of them ranked in the two professional divisions, making it one of the more successful stables.
