Isegahama stable
The stable's success was reflected in its postwar status as the leading stable in its "ichimon" or group of stables, which was called Tatsunami-Isegahama "ichimon" until 2006, when it became simply Tatsunami "ichimon" (reflecting the decline of the old Isegahama stable under former "ōzeki" Kiyokuni's leadership). However, in 2012, due to the head coach voting against the "ichimon"'s will in the Sumo Association's board elections, Tatsunami stable moved to the Takanohana "ichimon." Tatsunami "Ichimon" then renamed itself Isegahama "Ichimon" in January 2013. Tatsunami stable went independent in 2018, but after the Sumo Association indicated that stables must belong to an "ichimon", it aligned itself with the Dewanoumi group.
