Tamawashi Ichirō

is a Mongolian-Japanese professional sumo wrestler from Ulaanbaatar. Wrestling for Kataonami stable, his highest rank has been sekiwake. He made his debut in January 2004 and reached the top makuuchi division in September 2008. He has a makushita, a jūryō and two makuuchi division championships. He has eight gold stars for defeating a yokozuna, and five special prizes, holding the records of oldest man ever to win a special prize and a kinboshi after the July 2025 tournament. In January 2019, he won his first top-division championship, and his second in September 2022 at the age of 37, making him the oldest winner of the top division since the introduction of the six tournaments a year system in 1958.

Nicknamed "" (鉄人, ) and known as a "living legend" of the sport, Tamawashi has not missed a bout in his career to date (except for an enforced COVID-19 quarantine during the July 2022 tournament). Still an active wrestler, he has the longest streak of consecutive matches in sumo recorded history, setting the all-time consecutive match appearance record in his 1,631st consecutive match on 10 September 2024, during that month's grand sumo tournament in Tokyo.

At 41, he is also the oldest active jūryō wrestler. He is second only to Sadanoumi in most tournament appearances among current sekitori-ranked wrestlers.

In March 2024 Tamawashi acquired Japanese citizenship in order to remain in the Sumo Association as a coach upon his retirement. The injury did not affect his participation in the next tournament, which did not take place until May. However, after recording four consecutive make-koshi he dropped down to jūryō in January 2012. He made an immediate return to makuuchi for the March tournament, but fell back to jūryō on two further occasions, in September 2012 and May 2013. For the next few years he managed enough wins in tournaments to remain a fixture in the middle ranks of makuuchi.

In March 2015 he somewhat fortuitously won promotion to the san'yaku ranks for the first time, going straight to komusubi from the relatively low rank of maegashira 9 after most of the wrestlers above him made losing scores. It took him 38 tournaments from his top division debut to reach san'yaku, the slowest ever for a foreign-born wrestler. He was unable to hold on to the rank for more than a single tournament, but In May 2015 he earned his first gold star or kinboshi for an upset of a yokozuna, defeating Harumafuji. (He was also the slowest to earn a kinboshi among foreign-born wrestlers.) 2015 was the first year in his top division career that he was ranked above maegashira 10 for the whole year.

Tamawashi returned to the komusubi rank in November 2016 and produced a career-best performance as he recorded ten wins including another victory over Harumafuji and wins over three of the four ōzeki. He was rewarded with his first special prize for Technique, becoming the first wrestler since Asashoryū in 2001 to win his first special prize while ranked in san'yaku and was promoted to a career-high rank of sekiwake. The 77 career tournaments it took him to reach sekiwake is the fifth-slowest in sumo history. He is the first sekiwake from Kataonami stable since Tamanoshima in January 2004, and the first produced by the current stablemaster, the former Tamakasuga, since he took over in February 2010. He began the final day one win ahead of Takakeishō and secured his first top-division championship with a tsukiotoshi win over Endō. At 34 he became the second oldest first-time yūshō winner since the six tournaments per year system was established in 1958, after Kyokutenhō in 2012. On the day after his victory Tamawashi said "I still can't believe it. I now believe that dreams really can come true. I want to keep going even in my 40s. If I take it one match at a time, the results will come".

Tamawashi lost his sekiwake rank after recording only five wins against ten losses in the following tournament, but a 10–5 record from maegashira 3 in May, which included a kinboshi over Kakuryū, returned him immediately to sekiwake for the July 2019 tournament. However, as in March, he could only score 5–10 at this rank. By May 2021 he had fallen to maegashira 10, his lowest rank since 2016.

Since the retirement of Kotoshōgiku in November 2020, he has been the oldest man in the top division. In May 2022 he overtook Takamiyama to reach fourth place on the all-time list of consecutive career bouts with 1426.

Tamawashi's consecutive match streak reached 1448 matches before he was forced to withdraw from the July 2022 tournament on Day 13 due to a COVID-19 infection at Kataonami stable. However, the Sumo Association did not regard an enforced quarantine as breaking a run of consecutive appearances as it is through no fault of the wrestler, and so Tamawashi was allowed to continue his streak in the following September tournament. By the end of that tournament he had reached 1463 consecutive matches, passing former sekiwake Takatōriki for third on the all-time list.

In 2022 Tamawashi earned three consecutive kinboshi by defeating yokozuna Terunofuji in the January, March and May tournaments. Tamawashi is the first wrestler to earn a kinboshi against the same yokozuna in three straight tournaments since Wakamisugi pulled off the feat in 1965. Tamawashi's win in January ended Terunofuji's 23-bout winning streak, while his victory in March on Day 5 would end up being Terunofuji's final match of the tournament before pulling out. After he was beaten by the yokozuna in July, Tamawashi defeated Terunofuji again in September for his fourth kinboshi of the year, on his way to a 13–2 tournament victory. He was the first maegashira in 37 years to defeat all the yokozuna and ōzeki in a tournament. For the November 2022 tournament Tamawashi was promoted back to san'yaku for the first time since 2019, becoming at 37 year and 11 months the oldest wrestler to achieve this since Takamiyama in 1982. During his day 9 bout against Ura, Tamawashi used the extremely rare gasshōhineri (clasped hand twist down) kimarite, a move not seen in the top division since 1965. He finished that tournament with a 6–9 record and was subsequently demoted to maegashira 2 in the 2023 January rankings.

At the 2023 January tournament Tamawashi achieved a 9–6 winning record. In September of the same year, Tamawashi made his 1543rd consecutive appearance in a tournament, making him the second wrestler in history to have the most uninterrupted appearances in competition, tied with Fujizakura. On this occasion, the latter declared that, like Tamawashi, he was a wrestler who relied more on thrusting techniques, which he felt were less dangerous and therefore favoured longevity in the ring. In March 2024 he recorded his 1,300th match in the top division, losing it nonetheless to Endō.

Consecutive appearance record On 10 September 2024 Tamawashi appeared in his 1,631st consecutive professional sumo match, to break the all-time consecutive match appearance record previously held by former Aobajō (known at the time under the name Shiranui). The match against Kagayaki resulted in his first win of the that month's tournament, to which he received loud cheers from the spectators at the Ryōgoku Kokugikan. Tamawashi said after the match that the moment felt like winning the championship. "I think I've been able to do it thanks to the support of a lot of people, including the fans," he said. "Of course I've had to do it my way, but without their support I wouldn't have been able to do it." He added that he planned to continue his style of sumo as he approached the age of 40. the oldest to have done so up until that point was former in 1940. He finished his July 2025 tournament with 11 wins and a share of the runner up position (jun-yusho), and was also awarded the Shukun-shō for the third time, to break the record for the oldest Sanshō award, previously held by former Kyokutenhō.

During the 2025 November tournament, Tamawashi cemented his status as a veteran and senior member of the top division by facing Aonishiki, the second youngest wrestler in the top division. This match turned out to be the clash with the biggest age gap between competitors since World War II, with nineteen years, four months, and seven days between the two wrestlers. This record was then broken during the same tournament when Tamawashi faced Fujinokawa, the youngest top division wrestler, with a twenty-one-year age difference between the two. Later in the tournament, he won his 701st victory in , placing him in the top ten wrestlers with the most victories in the top division, tied with Takanohana. On November 30, the 2025 edition of Guinness World Records recognized him by formally certifying the record for the most consecutive matches since his debut, with 1,748 fights at the date of publication of the record.

Tamawashi would continue to break records at the 2026 March Tournament. On Day 4 of the tournament, Tamawashi fought his 1,471st Makuuchi bout, surpassing the record of 1,470 set by a fellow Mongolian-born former , Kyokutenhō. He broke this record 17 and a half years after making his Makuuchi debut in September 2008. Unfortunately, he could not mark this historic day with a win, as Ukrainian Shishi defeated him at the edge with a at the end of a spirited bout. He finished this tournament with a record of 5 wins and 10 losses.

The May 2026 tournament was Tamawashi's 100th tournament in , which put him in 3rd place for most tournaments ranked in , just behind Hakuhō and Kaiō. Tamawashi had fallen to a rank of west 13, the lowest rank he had occupied since returning to the top division in 2013. This was his first time occupying the west side of the rank, though. Because of this, Tamawashi had now occupied every rank on the Banzuke from to 16, except for east 2. Despite this, Tamawashi started the tournament with nine consecutive losses, struggling with an injury to his right calf. On Day 10, he got his first win of the tournament by defeating fellow mongolian Asahakuryū. This was his 713th victory in , surpassing Harumafuji and putting Tamawashi in 8th place on the all-time list.

Demotion to Tamawashi continued to establish himself as a long-standing wrestler, making his 100th appearance in the division at the March 2026 tournament. Despite suffering an injury to his right leg, he decided to continue competing, which resulted in a very poor record that forced him to be demoted to the division. After a series of poor performances early in 2026, Tamawashi found himself relegated to the division—a first for him since the May 2013 tournament. Tamawashi thus brought his run in the division to an end; although it remains the third-longest in the history of the sport.

Fighting style Unusually for a Mongolian wrestler, Tamawashi is an oshi-sumo specialist, who prefers pushing and thrusting techniques. His most common winning kimarite is overwhelmingly oshidashi (push out), which accounts for half his career wins; it is thought that his preference of oshi-sumo instead of yotsu-sumo (grabbing the belt and throws) that other Mongolian wrestlers prefer has been a key reason for Tamawashi maintaining his health and iron-man streak.

On the other hand, he is not comfortable fighting on the mawashi (belt), winning only around 5 percent of his matches by yorikiri (force out) in his career to date (the average is 25 percent). If an opponent gets an upper hand on Tamawashi's belt and quickly takes him to the edge of the dohyō and the tawara (the rice bales that mark the edge of the sumo ring), Tamawashi usually steps out to cut his losses and avoid major injury.

Personal life and other endeavors Tamawashi married a fellow Mongolian in 2012. His wife is the elder sister of another sumo wrestler, Tamashōhō, who became Tamawashi's stablemate in 2020 when he was transferred to Kataonami stable. Tamawashi's second child was born in January 2019, on the same day as his tournament championship was confirmed. and a baker, known for his cakes and cookies. In June 2026, it was announced that Tamawashi and his stablemate Tamashōhō would voice characters in the anime A Witch's Life in Mongol.

In 2021 he applied for Japanese citizenship with the help of his stablemaster, stating that he hoped to stay as a coach after retiring and "I want to give back." He took his shikona as his legal name.
