Onaruto stable

According to Japanese Wikipedia, Onaruto stable no longer exists under this name: it closed in January 1995 when the 11th Onaruto retired, and its disciples moved to Kiriyama stable. It was founded in 1960, when the 5th Onaruto, formerly Futaseyama, split from Asahiyama stable. In 1963 it merged back into Asahiyama stable, after the 5th Onaruto became the 16th Asahiyama. Takatetsuzan, the 11th Onaruto, started the stable again in 1975, and his highest rank was sekiwake. The stable belonged to the Tatsunami-Isegahama alliance, now the Isegahama ichimon. No yokozuna or ozeki is listed for the stable on that Wikipedia page.
