Daikokubō Benkei
better known by the ring name  is a former Japanese sumo wrestler and professional wrestler best known for his time in the Japanese promotion Big Japan Pro Wrestling (BJW). Sumo career

Kotani practiced judo in junior high school before switching to sumo wrestling after enrolling at Minabe High School. After high school, he received several offers from professional sumo stables, but decided to decline them and continued his amateur career at the collegiate level. He joined Nihon University's sumo club and in his fourth year, won the national student sumo championship to become college yokozuna. After graduating from university, Kotani opted to turn professional and joined the Hanakago stable. He made his professional debut in the March 1980 tournament (honbasho). Due to his amateur accomplishments, he was granted makushita tsukedashi status which allowed him to make his debut at the bottom of the makushita division. Even though he was given this special dispensation, he still struggled to break through to the jūryō rank and was stuck in makushita for four years. After changing his ring name (shikona) to  in May 1982, he began to produce stronger results and was promoted to jūryō in March 1984. Hanaarashi was only ranked in jūryō for a total of three tournaments. In his first tournament, he could only manage a 7-8 record after losing to Wakasegawa on the final day. Since he was ranked at the bottom of jūryō , he was demoted back down to makushita. Nevertheless, he returned to sekitori status in July 1984 and achieved a winning record. As a result he was promoted to the rank of jūryō 9, but could only manage 4 wins at that rank and was demoted from jūryō. After losing his sekitori status, Hanaarashi remained in makushita for another year before announcing his abrupt retirement prior to the start of the November 1985 tournament. The reason for this was because the Hanakago stable closed down and he was not accustomed to living in a stable with so many wrestlers as all the personnel from Hanakago stable transferred to the Hanaregoma stable.
