Toyonoshima Daiki - 豊ノ島 大樹 (born June 29, 1983) is a former Japanese professional sumo wrestler from Sukumo, Kochi. He made his debut in January 2002 and wrestled for Tokitsukaze stable. He reached the makuuchi division in May 2004 and has 10 special prizes as well as 4 kinboshi. His highest rank was sekiwake and he retired in July 2020.
Early Life[]
Kajiwara is the oldest son of a tofu maker. In his early years, he was an avid soccer player. However, his destiny changed after winning an area boys' sumo tournament championship.

Kajiwara as the junior high school yokozuna (c. 1998)
In junior high and high school, he was rivals with another future sumo wrestler who would go on to take the fighting name Kotoshogiku. Kotoshogiku is now a rival of his in professional sumo as well. In junior high school, he achieved the national status of junior high school yokozuna. After graduating from high school, Kajiwara joined Tokitsukaze stable through a connection a friend of his father's had with the stable. He was below the minimum height requirement of 173 cm but was allowed to make his debut after passing a secondary physical exam.
Career[]
Early Career[]
On entering the sumo world, Toyonoshima rose quickly through the lower ranks of sumo, winning two championships or yusho in the jonokuchi and jonidan divisions with perfect 7–0 records. Toyonoshima spent four tournaments in the sandanme division and in January 2003, he won all seven matches, but lost a playoff to stablemate Tokitenku. Upon reaching makushita, he would spend around a year in makushita before earning promotion to the juryo division in May 2004.
Juryo Career[]

Toyonoshima had a fast and successful stint in juryo. In his first tournament he produced a strong 11-4 record and was promoted to juryo 4 for the July 2004 tournament. In this tournament he produced another 11-4 record and earned promotion to the makuuchi divison in September 2004.
Makuuchi Career[]
Upon reaching the top makuuchi division he initially had little success and was demoted back to juryo twice. However, after winning the juryo championship in September 2005 with a strong 14–1 record, his fortunes began to turn and after some initial struggles, he rose steadily through the ranks of makuuchi.
In May 2006 Toyonoshima recorded only his second kachi-koshi or winning score in the top division, in his ninth tournament there. His first big success came in January 2007 when ranked at maegashira 9 he finished as runner up to yokozuna Asashoryu with an outstanding 12–3 record and earned his first special prizes for Fighting Spirit and Technique. In March he defeated two ozeki, Kotooshu and Chiyotaikai, and earned promotion to komusubi for May. At just 168 cm, or 5 ft 6 in (1.68 m) tall, he was the shortest wrestler to make komusubi in fifty years. However, before the tournament began he sprained his knee and ankle ligaments in a practice session with Asashoryu at his heya and could only manage four wins in his san'yaku (titled rank) debut.

Toyonoshima defeats yokozuna Hakuho to earn his first kinboshi
In September 2007 Toyonoshima became the first maegashira to defeat Hakuho since his promotion to yokozuna, earning his first kinboshi. He also defeated ozeki Kotooshu and Kotomitsuki. He finished with an 8–7 score and was awarded the Outstanding Performance prize. He achieved another winning record in the next tournament but faltered slightly with two 6–9 scores in January and March 2008. In May, however, he was on the leaderboard for much of the tournament and finished with joint runner-up honours and a share of the Fighting Spirit prize. He was one of seven wrestlers who NHK commentator Shuhei Nagao (the former Mainoumi) in 2008 called the "Seven Samurai" and identified as "holding the key" to a Japanese resurgence in sumo, which was dominated by foreigners in the top ranks. (The others were Goeido, Kisenosato, Kotoshogiku, Homasho, Toyohibiki and Tochiozan).
Toyonoshima returned to the san'yaku ranks at komusubi for the July 2008 tournament, where he defeated Asashoryu for the first time on the opening day. He finished with ten wins and another Outstanding Performance prize, and Kotoshogiku's losing record meant Toyonoshima was promoted to sekiwake for the September tournament, becoming the first wrestler from Tokitsukaze stable to reach the rank since Kurama in 1978. He fell short with a 6–9 score and was demoted to maegashira 1, but returned to komusubi for the January 2009 tournament.

Toyonoshima defeats ozeki Kaio
On the 7th day of the January 2009 tournament, Toyonoshima fell victim to ozeki Kaio's "kotenage" armbar throw. Toyonoshima appeared to suffer a severely hyper-extended elbow during the throw. Despite being doubled over in pain, Toyonoshima managed to bow to the ozeki and left the dohyo unassisted, until he was safely back in the dressing area, where medical attention appeared to be prompt. NHK English-language announcers later reported that Toyonoshima said he heard the elbow snap. The online-edition of the Yomiuri Shimbun reported that Toyonoshima was diagnosed with left-elbow sprain" and he was forced to forfeit the next day's scheduled bout against Kotoshogiku. Later news reports indicated that the Japan Sumo Association doctors told the 25-year-old rikishi to take a 6-week medical leave, and that Toyonoshima would bow out of the remainder of the 2009 Hatsu basho at the Ryogoku Kokugikan in Tokyo. This is the first occasion since his debut that he has missed any tournament bouts.
Toyonoshima returned to action in the March tournament in Osaka with his elbow strapped, but secured a winning record of 8–7 on the final day. In May, ranked at maegashira 3, he could manage only two wins in the first twelve days before winning his last three bouts. He produced his best performance of the year in November, a promising 11–4 score which won him his second Technique prize and opened up the possibility of promotion back to san'yaku in January 2010. However, due to Chiyotaikai's demotion to sekiwake and Kakuryu finishing 7–8, he had to settle for the maegashira 1 east position. He recovered from 3–6 down in the January tournament to post his majority of wins, and this returned him to the san'yaku ranks for the first time in seven tournaments, at sekiwake. He began brightly in the March tournament, opening with three consecutive wins, but he then faded and finished with just six wins against nine losses.

He was suspended along with over a dozen other wrestlers from the July 2010 tournament after admitting involvement in illegal betting on baseball. As a result, he was demoted to the juryodivision for the following September. He bounced back from this penalty with an impressive 14–1 record and took his second juryo championship, exactly five years after his first, guaranteeing himself promotion back into the top division. Fighting from maegashira 9 in November, he produced another 14–1 score, losing only to Kyokutenho and defeating two ozeki. He lost to Hakuho in a playoff for the yusho on the final day, narrowly failing to become the first wrestler ever to win back-to-back juryo and makuuchi championships (and the first Japanese-born winner of a top division tournament since 2006), but he received special prizes for Fighting Spirit and Technique. He was promoted to maegashira 1 East for the following tournament in January, the first time that a maegashira has won fourteen bouts and not been promoted to a san'yaku rank. He made a poor start to the January honbasho, losing seven of his first eight matches, but he recovered to earn his 8–7 majority of wins on the final day. This returned him to san'yaku for the (subsequently cancelled) March tournament. In the May 'technical examination' tournament he had an even worse start, losing nine of his first ten bouts and finishing on 5–10.
He returned to komusubi in September 2011 and recovered from a 1–7 start for the second time in his career to keep his rank with an 8–7 score. He rose to sekiwake in January 2012 but lost his rank after only scoring 5–10. He had a fine tournament in March, beating the ozeki Kotoshogiku and Kotooshu and sharing the Technique prize, which returned him immediately to sekiwake. In the May 2012 basho he defeated Hakuho for just the second time in the top division, sending the yokozuna crashing to his fourth loss of the tournament. In this period he managed to achieve enough winning tournaments to stay in the higher ranks of makuuchi, and also earned two gold star wins against yokozuna Harumafuji, which were ironically both losing tournaments for Toyonoshima.
Later Career[]

Toyonoshima (c. 2020)
Toyonoshima maintained his position in the upper maegashira ranks in 2015, earning a fourth kinboshi in March when he again defeated Harumafuji. In January 2016 he produced his best performance for several years when his 12–3 record included a win over the eventual winner Kotoshogiku and saw him tying for second place and being awarded the prize for Outstanding Performance. This was his tenth special prize, putting him level with Harumafuji and behind only Goeido and Aminishiki amongst active wrestlers. His performance saw him being promoted to sekiwake for the fifth time, and for the first time since May 2012. His next two tournaments were disappointing: he lost his sekiwake rank after recording only three wins in March and then posted a 5–10 record in May. He missed the July 2016 tournament after undergoing surgery for a left Achilles tendon rupture which occurred in training and as a result was demoted to juryo for the first time since 2010. He decided to skip the September tournament as well to allow his injury to fully heal, which meant a demotion to the makushita division. He is only the second wrestler to have fallen to makushita having previously taken part in a makuuchi division playoff, after Hokutoriki. He considered retiring at this point, but was persuaded to carry on by his young daughter.
Toyonoshima managed only a bare majority of four wins against three losses on his comeback in November 2016 but recorded six wins in January 2017. He strained his right calf in training shortly before the March 2017 tournament, and after missing his first match announced his withdrawal, although he returned from the 5th day. By January 2018 he had risen to makushita 5, but he was again affected by injury in this tournament, withdrawing on Day 5 and again on Day 9 having returned on Day 7. He won promotion back to the juryo division after a 6–1 record at makushita 1 in September 2018, after an absence of 13 tournaments. He is the sixth oldest wrestler post-World War II to return to juryo at 35 years and four months. In March 2019 he was promoted back to makuuchi. He is the third former sekiwake to fall to makushita and make a return to makuuchi after Kotokaze and Hoo.
Retirement from Sumo[]
In 2020 Toyonoshima fell back to the makushita division after suffering an arm injury, and he announced his retirement on April 17. His career record was 703 wins against 641 losses over 109 career tournaments, and his top division record was 493 wins against 524 losses over 71 tournaments. He assumed the elder name of Izutsu, previously held by the late Sakahoko, and will work as a coach in the Japan Sumo Association. He had reportedly been making payments towards the Nishikijima name previously intended for his ex-stablemate Shimotori before he was forced to quit sumo, but he was ultimately unable to acquire it, and the stock went to Asasekiryu instead.
Toyonoshima's retirement ceremony was held on May 28, 2022 at the Ryogoku Kokugikan. On January 4, 2023 he announced his departure as a member of the Sumo Association in order to pursue a career as a TV personality.
Controversy[]
Toyonoshima was suspended along with over a dozen other wrestlers from the July 2010 tournament after admitting involvement in illegal betting on baseball. As a result, he fell to the juryo division in September.
Personal Life[]
- Toyonoshima was married to pop singer Sunaho Takeuchi in February 2011 and the wedding reception was held that October in Tokyo's Metropolitan Hotel with around 600 guests attending.
- Toyonoshima's hobbies are listening to music, karaoke, fishing and bowling. The food he dislikes are green peas, raisins, and unmelted cheese.
Fighting Style[]

Toyonoshima defeats Kotooshu by shitatenage (underarm throw)
Toyonoshima was equally adept at grappling techniques, or yotsu-sumo, and pushing/thrusting techniques, oshi-sumo. His two most common winning kimarite were yorikiri, the force out, and oshidashi, the push out. His favorite grip on his opponent's mawashi was hidari-yotsu, a right hand outside, left hand inside grip, from which position he also regularly employed shitatenage, or the inner arm throw.
