Hōshōryū Tomokatsu (豊昇龍 智勝, born May 22, 1999 as Byambasuren Sugarragchaa ()) is a professional sumo wrestler from Mongolia and wrestles for Tatsunami stable. He is known for his throwing skills, even when measured among Mongolian sumo wrestlers, who tend to use throws more than average reflecting the skills used in Bökh. He is the nephew of former yokozuna Asashōryū. His highest rank has been sekiwake. Early life and sumo background Born as the second son of former yokozuna Asashōryū's brother, Sugarragchaa started wrestling at 11 years old. Upon graduation from middle school, he was scouted from Mongolia, and moved to Japan to attend Nippon Sport Science University Kashiwa High School. In his first year, as part of a school trip, he visited the Kokugikan in Ryōgoku and became interested in sumo. After consulting with his uncle he committed to trying sumo at the high school level. Though he had no previous experience, he quickly started getting good results in amateur sumo tournaments and was seen as having great potential. After high school he joined Tatsunami stable. During this time he emailed regularly with his uncle who gave him such advice as "build on your own strengths" and "don't put on weight quickly or you'll risk injury." Career Hōshōryū first stepped into the ring professionally in March 2018. He joined at the same time as Naya, who was also garnering attention as the grandson of the greatly respected yokozuna Taihō. In Hōshōryū's second tournament, he took the jonidan championship with a perfect 7-0 and was already regularly using throws and leg sweeps to win against his opponents. He only had one losing tournament, or make-koshi, in his rise through the lower ranks. This was a 3-4 performance at makushita 2 when he was on the cusp of promotion to the salaried ranks of jūryō in July 2019. He quickly bounced back the following tournament in September and with a 4-3 winning tournament, or kachi-koshi, he earned jūryō promotion for the November tournament in Fukuoka. His jūryō debut was a make-koshi, decided on the last day in a loss to fellow Mongolian Sakigake by overarm throw. Despite this setback he logged two 8-7 records in the next two consecutive tournaments. In the subsequent July 2020 tournament (held in Tokyo instead of the usual Nagoya due to concerns over the COVID-19 pandemic) he took part in a rare six man playoff, where
