Taiho Koki was the 48th yokozuna and won 32 top-division championships between 1960 and 1971, a total that stood as the record for more than forty years, until Hakuho passed it. The Japan Sumo Association’s own list of grand champions gives the bare outline: home town Teshikaga in Hokkaido, promoted for the November 1961 tournament, retired in May 1971, 32 titles. Everything past that outline on this page comes from the archive of Michihiro Taguchi, who has spent years working through the Taiho record — including his argument that one of the most famous numbers attached to Taiho, the 45-bout winning streak, is wrong.
The fastest climb on record. Eleven tournaments from his top-division debut to his first as a yokozuna — the shortest of the 33 grand champions since the 15-day format and the Yokozuna Deliberation Council came in, by Taguchi’s count.
An ozeki at 20, a yokozuna at 21. Two other men have made ozeki that young. Only one other, Kitanoumi, has worn the rope that young.
32 championships, and a title in every year he wrestled in the top division. Not even Hakuho, with 45, managed that.
The streak the record book calls 45. Taguchi puts it at 48 and counting, and says the Association should correct it.
The name is still on the ranking sheet. His grandson Oho fights in the top division today.
What the official record says
The Association publishes a single table of every grand champion in the sport’s history. Taiho’s row is short.
| Item | Detail |
|---|---|
| Number in the yokozuna line | 48th |
| Ring name | Taiho Koki |
| Home town | Teshikaga, Kawakami District, Hokkaido |
| Yokozuna from | November 1961 tournament |
| Yokozuna until | May 1971 tournament |
| Top-division championships | 32 |
That is the whole of the official summary. The Association’s searchable bout-by-bout records begin with the January 2013 tournament, so nothing about Taiho’s individual days on the ring can be pulled from that database. The numbers further down this page are Taguchi’s, taken from the rankings and results he has compiled and published in Dohyo no Mokugekisha, and they are labelled as such.
Born on Sakhalin, saved by seasickness
The Association lists Teshikaga in Hokkaido as his home town. Taguchi writes that he was born on southern Sakhalin, then Japanese territory, and that his father, long described in Japan as Russian, was more precisely Ukrainian.
In 1945 the boy and his family boarded a repatriation ship. His mother became seasick and they got off partway, at Wakkanai on the northern tip of Hokkaido. The ship sailed on and sank. Taguchi’s line is the plain one: he was allowed to live.
He entered Nishonoseki stable under his family name, Naya. The stablemaster, the former ozeki Saganohana, marked him out immediately and told him he was not like the others. The training was set apart too: the shiko and teppo quotas first, then the stable’s traditional hard practice and its butsukari sessions, which Taguchi describes as heavy enough to make a man faint. Three years later Naya reached juryo and was given the name Taiho.
Six tournaments from debut to champion
He entered the top division in January 1960 at 19 and won his first eleven bouts. Sumo had no juryo television coverage then, so to the public he simply appeared. When his bout came on, Taguchi records, the women’s side of the public bath went empty.
The man chosen to stop him was the komusubi Kashiwado, who did it with a shitate-dashi-nage, an underarm pulling throw. Taiho finished 12–3 and took the Fighting Spirit Prize. Then came the run that made him champion inside a year.
| Tournament | Rank | Record | Prize |
|---|---|---|---|
| January 1960 | New in the top division | 12–3 | Fighting Spirit |
| March 1960 | First time in the upper ranks | 7–8 | — |
| May 1960 | Maegashira | 11–4 | Fighting Spirit |
| July 1960 | New komusubi | 11–4 | — |
| September 1960 | New sekiwake | 12–3 | Technique |
| November 1960 | Sekiwake | 13–2, championship | none |
The last row is the one Taguchi keeps returning to. A sekiwake won the tournament outright and received none of sumo’s three special prizes. It had happened only once before, to Asashio in March 1957; writing in 2017, Taguchi counted just the two of them in the sport’s history. Taiho spent just six tournaments ranked below ozeki. In five of them he won 11 or more. He came away with three prizes. Kashiwado, over twelve tournaments below ozeki, took eight, four of them for technique.
Taguchi’s reading is that the selectors treated a Taiho championship as merely the thing that was supposed to happen. It is a small injustice, and he has written about it for nearly a decade.
The 7–8 that Taguchi says never happened
March 1960 is the only losing record in that table, and the only one of Taiho’s early career. He beat the ozeki Wakahaguro and the sekiwake Annenzan that fortnight and lost to the yokozuna Tochinishiki in what turned out to be their only meeting. Tochinishiki’s own verdict on the two young men who would take the sport from him was dry: Taiho and Kashiwado, he said, were children back then.
The bout Taguchi disputes is the one against Fukudayama. Reading the specialist magazines of the day, he concludes that Fukudayama’s elbow came down first and that Taiho was given the loss in error. One bout, and the fortnight turns from 8–7 into 7–8.
What that single decision cost, in Taguchi’s accounting, is a record nobody talks about: 27 consecutive winning tournaments from his top-division debut. His first losing fortnight would instead have been July 1964, the tournament in which he sat down as a yokozuna for the first time.
Promoted at 21, and the argument that came with it
Taiho and Kashiwado were raised to yokozuna on the same evening, after the September 1961 tournament. The recommendation was announced at 7pm on September 26. Taiho was 21 years and 3 months old. By Taguchi’s tally of the 33 grand champions promoted since the 15-day format and the Yokozuna Deliberation Council settled the modern shape of the sport, that ties Kitanoumi as the youngest, and the eleven tournaments it took him from his top-division debut is the shortest climb of the lot. He had already been an ozeki at 20; in Taguchi’s list of the 71 men promoted to that rank over the same period, only Kitanoumi and the wrestler who later became the yokozuna Takanohana did it as young.
| Taiho | Kashiwado | |
|---|---|---|
| Three tournaments before promotion | 11 wins, 13 wins and the title, 12 wins and the title | 10 wins, 11 wins, 12 wins |
| Age | 21 | 22 |
| Height and weight | 187 cm, 130 kg | 188 cm, 127 kg |
Kashiwado’s promotion was carried by Taiho’s. The stated reason was that his win rate as an ozeki was not inferior; consecutive championships, the usual test, he did not have. Sakai Tadamasa, the first chairman of the Yokozuna Deliberation Council, had said publicly that he wanted to hold the line at two straight championships with 13 wins or more.
The pairing gave the decade its name in Japan: the Kashiwado-and-Taiho era, written with one character from each man. Taguchi does not accept the label. Taiho won his second tournament as a yokozuna and ran off four in a row; Kashiwado did not win one until his twelfth. The gap, Taguchi argues, came out of how they fought. Kashiwado took the front of the belt and ran, and each of his bouts stood alone. Taiho defended, and counted — he wrestled the fifteen days as one problem. So the joint era was in substance the Taiho era.
The streak: 45 in the book, 48 by Taguchi’s reading
In September 1968 Taiho came back from five tournaments of absence, lost on the opening day to the technician Tochiazuma, and then won fourteen straight for the championship. He took the next two tournaments without dropping a bout. On the opening day of March 1969 he brushed aside the awkward Fujinokawa, and the run stood at 45.
Day two brought Toda, a newcomer who later wrestled as Haguroiwa. Toda charged and pushed him back. Taiho retreated, circling from the east side of the ring around to the front. Toda kept driving, and as he did his right foot kicked up the sand outside the straw. A moment later Taiho stepped out. The referee’s fan went to Taiho. Kotetsuzan, waiting his turn at ringside, said Toda’s foot had gone out. The five judges — Kasugano, the former Tochinishiki, in the chair, with Chiganoura, Kimigahama, Matsugane and Tamagaki — ruled for Toda.
In the dressing room Taiho said the fault was his for wrestling a bout like that, and the sport praised him for it. Back at his lodgings, watching the news, the anger arrived. He won twice more, then withdrew with acute pneumonia.
Taguchi’s position, which he has held in print since at least June 2014, is not that the decision was close. It is that Taiho won, that the streak therefore stands at 48 and would have run on further had he not been knocked off his stride into the withdrawal, and that the Association should correct the record even now. He writes it as 48 and counting. The one thing everyone agrees on is the consequence: the row over that bout is why video review came into sumo.
Readers who want the mechanics of how a call like that gets overturned can read our guide to mono-ii, when sumo’s ringside judges overrule the referee.
How rarely he lost to a rank-and-file wrestler
A kinboshi is the gold star a maegashira earns for beating a yokozuna, and it is the cleanest single measure of whether a grand champion leaks bouts downward. Taguchi has run the figure for fifteen yokozuna. Taiho’s, over 58 tournaments at the rank, comes out at 8 per cent.
| Measure | Figure |
|---|---|
| Tournaments as yokozuna | 58 |
| Record against maegashira | 306–28 (307–27 once the Toda bout is corrected) |
| Kinboshi conceded, as a share of those bouts | 8% |
| Tournaments wrestled to the end without conceding one | 28 |
| Most conceded in a single tournament | 3, and that happened twice |
| Most taken by one wrestler | 3, by each of Kairyuyama, Toyokuni and Uminoyama |
Put the other way: across a seven-bout run against the rank and file, he handed out six-tenths of a gold star.
Measured against the two men who came closest
Only Taiho, Chiyonofuji and Hakuho have won 30 top-division championships. Taguchi has set the three of them side by side twice, on two different questions.
| Taiho | Chiyonofuji | Hakuho | |
|---|---|---|---|
| Tournaments from 1st title to 30th | 52 | 55 | 49 |
| Record over that span | 582–93, 105 days out | 626–104, 95 days out | 637–83, 15 days out |
| Win rate over that span | .862 | .858 | .885 |
| Tournament in which the 10th title came | 15th | 24th | 18th |
| Fortnights of 12 wins or more in the upper ranks | 43 | 40 | 64 |
Taiho reached ten titles faster than either of them. Hakuho then pulled away, and Taguchi is direct about why: Hakuho barely missed a day, 15 across the whole span against Taiho’s 105. Of Taiho’s big fortnights, 33 per cent were 14–1 and 30 per cent were 13–2.
One record of his has survived all of it. Taiho won a championship in every calendar year from the year he entered the top division to the year he retired. Hakuho, with 45 titles, did not.
He came back from layoffs by winning
Modern grand champions tend to return from a withdrawal quietly and rebuild. Taiho returned by winning the tournament, and did it often enough that Taguchi treats it as a pattern rather than a run of luck.
| Layoff | What happened next |
|---|---|
| July 1964, out from day five — his 22nd tournament as yokozuna, with 13 titles already | Back-to-back championships |
| January 1966, out for the whole fortnight, aged 25, with 18 titles | Six championships in a row, the second such run of his career |
| July 1967 | His 26th championship |
| Five straight tournaments missed at 27 and 28 — one withdrawal after 11 wins, one more mid-tournament, then three fortnights fully absent | Trained through the summer tour, then won September 1968 and started the 45-bout run |
| July 1970, the retirement scare | The first comeback that did not end in a championship, though he still won 12 |
The 30th championship, in May 1969, brought him an ichidai-toshiyori: the right to stay in the Association under his own ring name rather than acquire one of the elder shares that normally have to be bought or inherited. In his late years the sport took to calling him the phoenix.
The fifth day, over and over
Taguchi’s account of the final stretch turns on an oddity he has written up more than once. Taiho’s last defeats kept landing on the same day of the fortnight — and two of the four were handed to him by the same man, the Takanohana of that era, a younger brother of the first Wakanohana whom the sport was calling its prince. (He is not the later yokozuna of the same name.)
| Tournament | Day five |
|---|---|
| September 1970 | Beaten by Takanohana, who took his first special prize for it |
| November 1970 | Beaten by Kurohimeyama — his only loss of a 14–1 fortnight that went to a playoff |
| March 1971 | Beaten by Daiju |
| May 1971 | Beaten by Takanohana. It was the last bout of his career |
Those bouts framed the ending. Takanohana beat Taiho for the first time in September 1970, and the two of them fought the hardest match of Taiho’s late career in January 1971. Takanohana threw him to the edge; Taiho stayed up on his toes as Takanohana tried to lift him out, and finally came down on top of him to win. Takanohana’s leg twisted underneath and he had to withdraw. Taiho took that tournament, his 32nd and last. Four months later, on the fifth day in May, Takanohana held on where Taiho could not, and Taiho retired.
Taguchi’s verdict
Taiho retired more than 40 years before Taguchi began covering sumo full time, so nothing here is eyewitness reporting and this site holds no photograph of him. What Taguchi does bring is the long look. Three positions run through his Taiho writing, and each is dated and argued rather than asserted.
- The streak is 48, not 45, and the Association should say so (June 11, 2014; repeated February 19, 2025 and June 28, 2026). His grounds: the referee gave the bout to Taiho, the wrestler waiting at ringside said Toda’s foot was out, and the reversal came from five judges in an era when, as Taguchi puts it plainly, objections were raised along stable-lineage lines as a matter of course.
- He was robbed twice, not once (February 19, 2025). The Fukudayama bout in March 1960 cost him a run of 27 consecutive winning tournaments from his debut in the top division.
- The Taiho era ended in May 1969, at the 30th title (February 17, 2024) — and the joint era it is usually filed under never really existed, because the two men were never close after the promotion.
The promotion argument has a live edge to it. Writing in April 2026 about how Taiho and Kashiwado were raised together, Taguchi set out his own standard against the one used in 1961 and still used today: he does not accept a promotion decided on a three-month slice of a six-tournament year, and wants five tournaments of steadiness looked at instead. He has applied that same test to the current grand champions, which is why he can praise Taiho’s rise and refuse the second half of the label attached to it in the same breath.
The training, and the name
Taiho disliked being called a natural. Nobody, he thought, had worked harder. The stories bear him out: he took on the five ozeki of the day — Kitabayama, Sadanoyama, Tochinoumi, Tochihikari and Yutakayama — in morning practice and did not lose. Young wrestlers stood watching for the bout where he would finally go down, and it never came.
The magazine Ozumo counted his sessions on an eleven-day tour stop at Hiroshima in April 1964, two weeks after he had taken his tenth championship without dropping a bout: about twenty on the first day, twenty on the second, twenty-six on the third against six young men lined up in turn, twenty-five on the fourth. The elders quoted in the piece had given up arguing. The gap, one of them said, is only going to widen.
He was not universally admired at the time. Critics said he had no set pattern, that he went backwards when he should have attacked, that his sumo could not be copied. What he actually did well, Taguchi notes, was flexible: he got his hand inside and turned it up, pulled his man in and walked him out, and threw with the scooping sukui-nage.
His standing outside the sport is fixed by one phrase from the period, “Kyojin, Taiho, tamagoyaki” — the Yomiuri Giants, Taiho, and the sweet rolled omelette, the three things ordinary people were said to love. A baseball dynasty, a man, and a piece of comfort food. He was the only individual on the list.
When the yokozuna Tamanoumi died while still active, at 27, and the sport was suddenly short of grand champions, someone floated the idea of putting the retired Taiho in a wig and sending him back out. Taguchi reports the remark that followed as the measure of what he had been: Taiho would manage 12 wins on a bad day.
The name is still on the ranking sheet. His grandson Oho fights in the top division out of Otake stable, the dojo Taiho founded.
Frequently asked questions
How many championships did Taiho win?
Thirty-two, which the Japan Sumo Association lists in its table of past yokozuna. The total was the record for more than 40 years until Hakuho passed it, and Taiho won at least one in every calendar year he spent in the top division — a record Hakuho did not match.
Was Taiho’s winning streak 45 bouts or 48?
The official figure is 45, stopped by Toda on the second day of March 1969. Michihiro Taguchi argues it should be 48 and counting: the referee gave that bout to Taiho, the wrestler waiting at ringside said Toda had stepped out first, and five judges overturned it. Taiho withdrew days later, so the run never resumed. The dispute is why video review was introduced.
How young was Taiho when he became a yokozuna?
21 years and 3 months, which ties Kitanoumi as the youngest since the 15-day format settled. He had been an ozeki at 20, and it took him eleven tournaments from his top-division debut to his first as a grand champion — the shortest climb of any yokozuna in that era, by Taguchi’s count.
Why is he linked with Kashiwado?
They were promoted to yokozuna on the same evening in September 1961, and the decade is usually called the Haku-Ho era after them. Taiho had two straight championships going in; Kashiwado had 10, 11 and 12 wins, and was carried up alongside him on the strength of his win rate as an ozeki. Taiho won his second tournament as a yokozuna; Kashiwado did not win one until his twelfth.
How often did Taiho lose to a rank-and-file wrestler?
Rarely. Over 58 tournaments as yokozuna his record against maegashira was 306–28, a kinboshi rate of 8 per cent, and he went through 28 full tournaments without conceding one. Kairyuyama, Toyokuni and Uminoyama took three each, more than anyone else.
Is Taiho related to any current wrestler?
Yes. His grandson fights in the top division as Oho, out of Otake stable — the stable Taiho founded. Oho reached sekiwake in 2025.
When did Taiho retire?
May 1971. His last bout was on the fifth day, against Takanohana — the fourth tournament in a row in which the fifth day had beaten him. He had won his 32nd and final championship four months earlier.
Reporting note: the official summary in this article — the position in the yokozuna line, the home town, the years at the rank and the 32 championships — comes from the Japan Sumo Association’s published list of past grand champions, retrieved on August 6, 2026. Everything else is drawn from Michihiro Taguchi’s research published in Dohyo no Mokugekisha: his articles on the streak and the reversed decision (June 11, 2014; February 19, 2025), the kinboshi rate (June 28, 2026), the comeback championships (March 31, 2026), the last years and the fifth-day pattern (October 18 and 20, 2025; February 17, 2024), the special prizes (September 30, 2017), the joint promotion with Kashiwado (April 26, 2026; February 16, 2017), the age and speed records (August 12, 2016; November 5, 2021; April 19, 2020), the comparison with Hakuho and Chiyonofuji (August 13, 2014; December 13, 2023) and his practice sessions (August 17, 2019). Where a figure is his own count rather than an Association publication, this page says so. The Association’s searchable bout-by-bout records begin with the January 2013 tournament, so no part of Taiho’s career can be checked against that database.
