Zensho Yusho: Sumo’s Perfect 15-0 Championships
A zensho yusho is a championship won without a single loss. In today’s 15-day format that means a flawless 15-0; in earlier eras, when tournaments ran for 11 or 10 bouts, it meant winning every one of those. It is the most complete way to win. As the former yokozuna Akinoumi, Mr. Nagata, put it: “There is a world of difference between a perfect record and a single loss.” Only 11 wrestlers have achieved three or more zensho yusho. Hakuho leads the list with 16, followed by Futabayama and Taiho with 8 each.
What a zensho yusho is
In sumo, the top-division (makuuchi) champion of a tournament takes the yusho. Most champions drop at least one bout along the way. A zensho yusho is different: the wrestler comes through the entire tournament unbeaten. The word zensho means “all wins,” and pairing it with yusho describes a championship without a blemish.
What “all wins” adds up to depends on the era. The modern tournament lasts 15 days, so a perfect run is 15-0. But the schedule was shorter in the past. Some of the historic perfect championships on this list were 11-0, and a few were 10-0, simply because that was the length of a tournament at the time.
Mr. Nagata, the former Akinoumi, captures why the feat carries such weight: “There is a world of difference between a perfect record and a single loss.” One defeat still leaves you a champion. Zero defeats puts you in another category entirely.
A note on counting: the official championship system
Japan’s official championship system dates to 1926 (Taisho 15). That starting line matters for how the records are tallied. Tsunenohana, for instance, is counted here with 8 championships and 2 zensho yusho under the official system.
The wrestlers with three or more zensho yusho
Across the entire history of the official system, just 11 wrestlers have recorded three or more perfect championships. Here they are, with their zensho yusho totals.
| Wrestler | Zensho yusho |
|---|---|
| Hakuho | 16 |
| Futabayama | 8 |
| Taiho | 8 |
| Kitanoumi | 7 |
| Chiyonofuji | 7 |
| Haguroyama | 4 |
| Takanohana | 4 |
| Asashoryu | 4 |
| Kitanofuji | 3 |
| Wajima | 3 |
| Harumafuji | 3 |
Hakuho stands apart at 16. Futabayama and Taiho follow with 8 apiece, then Kitanoumi and Chiyonofuji with 7. Four wrestlers reached the threshold with exactly three.
Futabayama: the only sekiwake to do it
Futabayama is the one wrestler on this list to have won a zensho yusho while still ranked at sekiwake, rather than at the sport’s summit. That perfect run was an 11-bout sweep — the limit of the era, when tournaments were shorter. At the time, Futabayama was in the middle of his 69-bout winning streak.
His career rate is striking. Of Futabayama’s 12 championships, 8 were zensho yusho — a perfect-championship rate of 66.7 percent.
Haguroyama’s wartime perfect runs
Haguroyama collected 4 zensho yusho. Two of them were 10-bout perfect championships, won during the upheaval of the war and postwar years, when the tournament schedule was disrupted and shorter.
Consecutive zensho yusho as an ozeki
Three wrestlers strung together back-to-back zensho yusho while ranked at ozeki: Futabayama, Takanohana, and Harumafuji.
- Futabayama did it in the two-tournaments-a-year era at 11-0, in his debut tournament as a new ozeki and the one that followed — a 100 percent win rate across his ozeki run.
- Takanohana achieved his in his 10th and 11th tournaments at ozeki, which were his 6th and 7th career championships.
- Harumafuji did it in his 21st and 22nd tournaments at ozeki, his 3rd and 4th career championships.
The great yokozuna: which championship was the perfect one
Among the so-called ten great yokozuna, here is the career championship number at which each of them — apart from Takanohana — first turned in a zensho yusho:
| Wrestler | Career championship that was a zensho yusho |
|---|---|
| Taiho | 11th |
| Kitanoumi | 8th |
| Chiyonofuji | 8th |
| Asashoryu | 5th |
| Hakuho | 3rd |
Hakuho reached his while still an ozeki. The others did it as yokozuna.
Taiho’s hard road to a perfect championship
Taiho did not arrive at his first zensho yusho easily. In that tournament, his great rival Kashiwado was absent for the entire schedule. Taiho also became the wall that stopped others: he stood in the way of perfect runs by Kitanofuji and Tamanoumi. Both of those wrestlers only completed their own zensho yusho after Taiho had retired.
Hakuho: most in number, but not in rate
Hakuho holds the record for the most zensho yusho with 16. But of his 45 championships overall, those 16 perfect ones work out to a rate of 35.6 percent.
Set that against Futabayama’s 66.7 percent, and the contrast is clear. Hakuho won the most perfect championships outright, yet by rate he comes nowhere close to Futabayama.
The current drought
The most recent zensho yusho was Terunofuji’s, at the November 2021 (Reiwa 3) tournament. Since then, 20 tournaments have gone by without another perfect championship. When the next one will come, and who will manage it, is anyone’s guess.
