Kitanoumi Toshimitsu, Japanese sumo wrestler, the 55th Yokozuna (died 2015)

Kitanoumi Toshimitsu , born Toshimitsu Obata , was a Japanese professional sumo wrestler from Sōbetsu, Hokkaido. He entered professional sumo at the age of 13 and set several youth-related records, including promotion to the highest rank of yokozuna at the age of 21. Despite being the most dominant wrestler in the sport during the 1970s with 24 tournament championships in his career, he was not popular with fans and was viewed as a villain, earning him the nickname the "Hatefully Strong Yokozuna". At the time of his death he still held the records for most tournaments at yokozuna (63) and most bouts won as a yokozuna (670), but they have since been surpassed. Following his retirement in 1985 he established the Kitanoumi stable. He was chairman of the Japan Sumo Association from 2002 until 2008, and again from 2012 until his death.

Makuuchi (幕内), or makunouchi (幕の内), is the top division of the six divisions of professional sumo. Its size is fixed at 42 wrestlers (rikishi), ordered into five ranks according to their ability as defined by their performance in previous tournaments.
