is a Japanese professional sumo wrestler from Adachi, Tokyo, Japan. He entered sumo in March 2003, reaching the top makuuchi division in July 2011. His highest rank to date has been maegashira 4, which he achieved in July 2013 after he put together five straight kachi-koshi or winning records in the top division. He was last ranked in in 2015 and since then has been in the jà «ryà  and makushita divisions. He wrestles for Tamanoi stable.
Kazuyoshi Shibuya went to primary school and junior high school in the Adachi, Tokyo. He began practicing sumo in his fifth year of primary school and in his sixth year came in a second in a national primary school sumo tournament. He had been going to Tamanoi stable regularly for practice since primary school as his sumo club had an ongoing relationship with the stable, and this was the stable he ultimately chose to join after junior high school.
He made his debut in March 2003, the same tournament as later jà «ryà  contemporary Sadanoumi. He rose gradually to the ranks of makushita and was working his way up, but would start to suffer from pain due to a neck injury and would eventually drop back down to the fourth tier sandanme division. After two tournaments here he would slowly work his way through makushita again. He reached the elite sekitori ranks in January 2011, a little over seven years after his professional debut.
His rise through jà «ryà  and onto the top-tier makuuchi division was surprisingly smooth compared to his struggles in lower divisions, undoubtedly helped by the forced retiring of several jà «ryà  and lower makuuchi wrestlers due to an unprecedented match-fixing scandal. In these circumstances, a relatively average record of 9âÂÂ6 at jà «ryà  #8 would allow him promotion to the makuuchi division in July of that year.
A member of Tamanoi stable, he is the first top division wrestler produced by Tamanoi's head coach, the former ozeki Tochiazuma Daisuke. This first makuuchi tournament would be a very successful 10âÂÂ5 record which would allow him to rise higher through the ranks, but his following four efforts were all losing tournaments which saw him slide back to maegashira 15. A very disappointing 3âÂÂ12 score in the May 2012 tournament saw him demoted back to the jà «ryà  division, but upon his return to the top division he put together a string of five consecutive 8âÂÂ7 records which eventually saw him promoted to his highest rank to date of maegashira 4.
He sat out the March 2014 tournament, recuperating after a detached retina operation. This led to his demotion back to jà «ryà  for the following May 2014 tournament where he only managed a 7âÂÂ8 record. He won the jà «ryà  division championship in March 2015 and was promoted back to makuuchi, but his return to the top division lasted only one tournament as he could only score 3âÂÂ12. This has been his last makuuchi appearance to date. He was demoted to the makushita division after the September 2016 tournament, but promoted back to jà «ryà  for March 2017 after a 5âÂÂ2 score at makushita 3 in January. His stay in jà «ryà  lasted only one tournament and he was back in the makushita division in May 2017. He reached the top rank of the makushita division, #1 East, in May 2019 but just failed to get the majority of wins that would have returned him to jà «ryà Â, scoring 3âÂÂ4. However, he remained near the top of the makushita division and he returned to jà «ryà  after 18 tournaments away for the July 2020 tournament (originally scheduled for May). He maintained his position in jà «ryà  for the September 2020 tournament, but was prevented from entering it due to a COVID-19 outbreak at his stable. Fujiazuma was one of the 19 wrestlers who tested positive. He and the other members of the stable were allowed to keep their ranks for the following tournament in November. In this tournament Fujiazuma lost every one of his fifteen matches, the second straight jà «ryà  wrestler to suffer this fate after Oki in the previous tournament.
Fujiazuma wins most of his bouts by pushing and thrusting; his most common winning kimarite or technique is oshi dashi (push out).
