Wakakà Âyà « Masaya (born 24 February 1984 as Masaya Yakigaya) is a former professional sumo wrestler from Funabashi, Japan. His highest rank was komusubi. The last two characters of his ring name were taken from his mentor and coach at à Ânomatsu, the former Masurao. He was only the second wrestler from his stable to reach the top division. He was runner-up in one tournament and earned one special prize, for Fighting Spirit. He is now a sumo coach.
Two years after his birth in Funabashi, his father was killed in a car accident and he was subsequently raised alone by his mother. Ã Ânomatsu stable being very near the home of one of his relatives, he began visiting it from a young age. This eventually led to him entering the stable in 1999.
Fighting under his own surname of Yakigaya, he rose steadily through the ranks until reaching sandanme where he started to struggle. He managed to reach makushita in September 2002 but was demoted back to sandanme after one tournament. In 2003, he missed two tournaments, but upon returning earned two impressive records topped off with a perfect 7âÂÂ0 record to win the sandanme championship in the last tournament of that year. He fought for four years in the makushita ranks with occasional temporary demotions to sandanme before finally achieving a record that enabled his promotion to the second division, jà «ryà Â, in January 2008. To mark his arrival in the elite sekitori ranks he changed his shikona to Wakakà Âyà «.
After a year and half in jà «ryà  with two demotions to makushita he managed a 9âÂÂ6 record at the jà «ryà  2 rank and was promoted to the bottom of the makuuchi division in July 2009. He only managed a 4âÂÂ11 record and fell back to jà «ryà Â. After a one off 6âÂÂ9 record this tournament, he took in a string of winning records over the next several tournaments to again reach the top division makuuchi in May 2010. This time he proved himself with a 10âÂÂ5 record that would have allowed him to fight in the next tournament at a career high maegashira 8. However, at this time, he admitted to having been involved in baseball gambling along with a number of other higher ranked wrestlers and was forced to sit out the tournament and was demoted back to jà «ryà  having never fought at his (then) highest achieved rank.
He bounced back from this setback with two winning tournaments, the second being an impressive 10âÂÂ5 at jà «ryà Âs highest rank. This awarded him another chance to prove himself in makuuchi in the January 2011 tournament. Wakakà Âyà « and Toyohibiki were the last two wrestlers to again reach the top division after being demoted from it in the gambling scandal. After an 8âÂÂ7 score at maegashira 10 in the May Technical Examination Tournament, he reached the upper maegashira ranks for the first time at #3. He managed to defeat two à Âzeki (Kotooshu and Kaià Â) but finished with a losing score of 5âÂÂ10. His best performance in the top division came in November 2011 when he finished runner-up to yokozuna Hakuhà  with a score of 12âÂÂ3 and was awarded his first sanshà  or special prize, for Fighting Spirit. It also saw him promoted to the sanyaku ranks for the first time at komusubi for the following tournament in January 2012. However, a decline in his performances saw him demoted back to the jà «ryà  division at the end of 2012 having scored only 4âÂÂ11 at maegashira 13 in November. After a few years as a fixture in the second division he retired mid-tournament in September 2014 when his losing record had assured his demotion to the unsalaried ranks.
Wakakà Âyà « has stayed in the sumo world as a coach at à Ânomatu stable. He has secured one of the Sumo Association's 105 toshiyori-kabu or elder names, and is now known as Shiranui Oyakata. His danpatsu-shiki or official retirement ceremony was held at the Ryogoku Kokugikan on January 31, 2015.
Wakakà Âyà « was an oshi-sumo specialist, preferring pushing and thrusting techniques to fighting on the mawashi. His most common winning kimarite were oshi-dashi (push out), tsuki dashi (thrust out) and hiki-otoshi (pull down).
