Wakakirin Shinichi (若麒麟 真一, Wakakirin Shin'ichi), born September 21, 1983, as Shinichi Suzukawa (鈴川真一, Suzukawa Shin'ichi), is a former sumo wrestler from Hyōgo prefecture in Japan. His highest rank was maegashira 9. He was thrown out of the sport in February 2009 after being arrested for cannabis possession. In 2010 he became a professional wrestler.

Born in Kawanishi, his father ran a restaurant. He has a younger brother. He did baseball at elementary school. He was asked to join Oshiogawa stable while visiting the heya with a classmate of his father, and was contacted a number of times after that.^[1] He made his professional debut in March 1999. He is the fourth wrestler from that class to make the top division, following Kotomitsuki, Takamisakari and Hamanishiki, but the first to do so after making his debut at the lowest level of sumo entry, mae-zumo. He began competing under his own surname, but upon reaching the second highest jūryō division for the first time in July 2004 his stablemaster Oshiogawa Oyakata honoured him with the name of Wakakirin. The "Kirin" part of his name, meaning giraffe or qilin, had only been given to three previous wrestlers: his own stablemaster (former ōzeki Daikirin), former sekiwake Kirinji, and Tamakirin, who quit sumo to become a professional wrestler.

Wakakirin scored an impressive ten wins in his jūryō debut, but in January 2005 he suffered an anterior cruciate ligament injury that forced him to sit out two tournaments, resulting in demotion back to the unsalaried makushita division. The injury reduced the effectiveness of his favoured tsuppari, or thrusting techniques, and although he returned to the second division in January 2006 he could manage only four wins and was immediately demoted once again.

He slowly returned to full fitness and after a series of solid performances he took his second makushita championship in May 2007 with a perfect 7-0 record from the rank of makushita 3, to earn promotion back to jūryō. After scores of 10-5 in July and 9-6 in September, he was promoted to the top makuuchi division for the November 2007 tournament. In April 2005 Oshiogawa stable was absorbed into Oguruma stable, in anticipation of Oshiogawa Oyakata's retirement the following year. Wakakirin is the third member of Oguruma stable to make his top division debut, following Takekaze and Yoshikaze.

Wakakirin achieved ten wins in his top division debut, a feat that normally wins the Fighting Spirit Award, but he missed out, the prize going to Baruto instead. He was promoted to what was to be his highest rank of maegashira 9 for the January 2008 tournament, but disappointing scores of 4-11 there and 6-9 in March meant he was demoted back to the jūryō division. He missed out on a kachi-koshi winning score on the final day in May 2008, falling to 7-8. He scored 7-8 once again in July. He remained in the top half of jūryō after that, but did not win promotion back to the top division. He produced a good 9-6 score at jūryō 3 in January 2009 but lost to Tamawashi on the final day when a win would have virtually guaranteed a return to makuuchi.

In 2010, Wakakirin, still using his sumo name returned to the ring as a professional wrestler, training in Antonio Inoki's Inoki Genome Federation (IGF) stable. His first match was on the IGF-13 card in December, when he defeated Mark Coleman by referee stop. The match was controversial, and Coleman's colleague, Phil Baroni accused Wakakirin of shooting on Coleman in what was supposed to be a worked match. He made his comments on this on the Nightmare of Battle website.^[12]

Wakakirin's next fight was scheduled for December 31, 2010, against Bob Sapp, but the match never took place as Sapp refused to leave his dressing room. He was also scheduled to face Kimbo Slice on February 5, 2011, in Fukuoka, but that fight never took place as Kimbo went down with an injury. In 2011 he was named the sport's rookie of the year by Tokyo Sports.^{[citation needed]}

His first MMA fight was in December 2012 when he lost to Mirko Cro Cop.^[13] In April 2014 he was defeated by Bob Armstrong at Inoki Genome Fight.^[14]

In October 2013 he formed a tag team with fellow ex-sumo wrestler Kirinowaka.^[15]

He left the IGF in 2017 and participated in a martial arts event run by the ISM, Inoki's new company.^[16]

In March 2021 he was arrested again on suspicion of possessing cannabis.^[16][17]
