Kasugano stable (春日野部屋 Kasugano-beya?) is a stable of sumo wrestlers, part of the Dewanoumi ichimon or group of stables. As of January 2017 it had 22 wrestlers. It was one of the most successful stables in 2013, with six sekitori wrestlers, including the Georgian and the now retired Japanese born (but Korean national) , who used the current head coach's old ring name.
It was founded in the mid 18th century by a wrestler named Kasugano Gunpachi. It became inactive for a long time but was led in the Meiji period by a referee named Kimura Soshiro (this is no longer allowed as oyakata must now be former wrestlers). He adopted as his son the 27th yokozuna , who led the stable for over thirty years. He in turn adopted as his son the 44th yokozuna , who became the head in 1959 whilst still an active wrestler and later served as the chairman of the Japan Sumo Association. took over upon Tochinishiki's death in 1990 and led the stable until his retirement in 2003. The stable absorbed Mihogaseki stable in 2013 when its stablemaster (former ōzeki Masuiyama Daishirō II) reached the mandatory retirement age.
Many wrestlers at this stable take ring names or shikona that begin with the character 栃 (read: tochi), in deference to the long line of owners who have used this character in their shikona. It originally referred to , where Tochigiyama came from, but subsequent owners were not from there and the prefix no longer has a geographical meaning.
