Washūyama Yoshikazu

His shikona or sumo name was derived from the Washuzan mountain in his native Okayama prefecture.[1] (He was to become so popular that people would refer to the mountain as Washuyama.[1]) He made his professional debut in March 1967, reaching the second highest jūryō division in July 1972. He was promoted to the makuuchi division in May 1973 and made an immediate impression, finishing as the tournament runner-up with 11 wins and earning the Fighting Spirit prize. However, injury problems over the next couple of years prevented him from progressing much further and he was demoted back to the jūryō division on two occasions. His fortunes turned around towards the end of 1975 when he won his second Fighting Spirit prize, and in January 1976 he was once again tournament runner-up. This earned him promotion to the titled sanyaku ranks for the first time in March 1976 at the rank of komusubi. Another strong showing earned him immediate promotion to sekiwake, which was to be his highest rank.

In 1982 Washuyama dropped to the jūryō division once more, although he kept on fighting until November 1985 when he finally announced his retirement at the age of 36.

Washuyama was one of the lightest sumo wrestlers ever seen in the top division, at around 100 kg and rather short at 175 cm. He was very popular with the tournament crowds, earning the nickname of chibikko gangu or "midget gang" for the way he seemed to swarm around his larger opponents attacking from all sides.[1] He became a real nemesis for the giant Hawaiian wrestler Takamiyama,[1] who was nearly twice his size. His technical skill is evidenced by the five Ginosho, or Technique Awards he picked up during his career.

Washuyama remained in the sumo world as a coach at his old stable, under the name Sakaigawa. In 1996 he assumed the Dewanoumi name and took charge of the stable while the previous head, Sadanoyama, became Sakaigawa and concentrated on his role as the Japan Sumo Association chairman. Washuyama was also on the Sumo Association's board as a director. He reached the mandatory retirement age for an oyakata of 65 in April 2014 and handed over control of the stable to former maegashira Oginohana. In March 2018 he was appointed as a Hyogi-in-kai or outside voter in the Sumo Association, although he has no oyakata status.
