Kasugayama stable (春日山部屋, Kasugayama-beya) was a stable of sumo wrestlers, part of the Isegahama ichimon or group of stables. In its modern form it dates from 1954 when it was re-established by former ōzeki Nayoroiwa who led it until his death in 1971. It went out of existence in 1990 when the stablemaster, former maegashira Ōnobori, reached the mandatory retirement age of sixty-five, and was absorbed by Ajigawa stable, but it was revived by Kasugafuji after his retirement as an active wrestler in 1996. As of January 2016 it had 23 wrestlers. Its only wrestler to reach the top division was the Korean born Kasugaō who retired in 2011.
