Yamashina stable

According to Japanese Wikipedia, Yamashina stable no longer exists: it closed in January 1933 on the death of its 8th head, and no successor or merger is stated. The 8th head, formerly Kashiwayama Goro of Isenoumi stable and a former makuuchi (the top division) wrestler with the exact rank not stated, took the name in January 1914. After the 7th head died in March 1909, the stable's wrestlers moved to Dewanoumi stable. No yokozuna or ozeki is listed for the stable in the Japanese Wikipedia article; the highest rank it names is sekiwake (Kashiwayama Daigoro).

After the 7th head died in March 1909, the stable's wrestlers moved to Dewanoumi stable, among them Shakagatake Shotaro, who later reached makuuchi (per Japanese Wikipedia).

The 8th head, Kashiwayama Goro, trained Kashiwayama Daigoro up to the rank of sekiwake (per Japanese Wikipedia).
