Introduction
The 2026 senior World Championships were held in Astana, Kazakhstan. The women’s freestyle competition ran from October 27 to 30 and crowned a world champion in each of the 10 weight classes: 50, 53, 55, 57, 59, 62, 65, 68, 72 and 76kg. The finals were held on October 28 (50, 57, 65 and 76kg), October 29 (53, 62, 68 and 72kg) and October 30 (55 and 59kg).
Japan won seven medals: two gold, two silver and three bronze, with a medal in seven of the 10 weight classes. Gold went to Susaki Yui at 50kg and Kiyooka Moe at 53kg. Silver went to Nagamoto Sena at 57kg and Ozaki Nonoka at 62kg. Bronze went to Harada Nagisa at 55kg, Ikehata Nana at 65kg and Yoshitake Mahiro at 72kg.
This report uses official UWW data to compare how all 10 gold medalists won their titles, using a metric called MSW. We also review the results in every weight class and the performances of all 10 members of Team Japan.
What Is MSW? A Metric That Uses Match Time to Measure the Quality of a Win
MSW (Most Successful Wrestler) is a metric proposed by Dr. Kristijan Slacanac of UWW Performance Data Analysis. Two gold medals can look identical on paper, even though one wrestler may have won fast and by wide margins while another won a string of close decisions. MSW boils that difference down to a single number.
- MSW = WQ + CPdiff
- WQ — technical-point differential per minute: (total TP scored − total TP conceded) ÷ total match time in minutes.
- CPdiff — classification-point differential per bout: (total CP earned − total CP conceded) ÷ number of bouts. CP depends on how a bout is won: VFA (victory by fall) = 5, VSU (victory by technical superiority, a 10-point lead in women’s freestyle) = 4, VPO (victory by points) = 3. A trailing 1, as in VSU1 or VPO1, means the losing wrestler also scored and receives 1 CP.
In short, WQ rewards how large a lead was built, and CPdiff rewards how high-grade the wins were. The more a wrestler builds big leads in little time and finishes with falls or technical superiority, the higher the MSW climbs.
This time, the official UWW bout-by-bout records include match times, so we calculated MSW in its original form. Match time is the match-clock time at the end of each bout. A win on points (VPO or VPO1) is recorded as 6:00 in the official data, and we used that figure as it stands. There is one exception: the official data has no match time for one of Susaki Yui’s bouts, her quarterfinal, so we used the time reported by the Japanese outlet Wrestling Spirits (see the note below the ranking table). Bouts that end in a withdrawal or disqualification are not truly contested, so they are excluded from the calculation. None of the 41 bouts fought by this year’s 10 gold medalists ended that way.
MSW Ranking of the Gold Medalists
The 10 gold medalists, ranked by MSW from highest to lowest.
| Rank | Weight | Country | Wrestler | Bouts | Total time | TP (for-against) | CP (for-against) | MSW |
|---|---|---|---|---|---|---|---|---|
| 1 | 57kg | CHN | HONG Kexin | 4 | 11:12 | 41-0 | 16-0 | 7.66 |
| 2 | 50kg | JPN | SUSAKI Yui | 5 | 19:36 | 44-0 | 20-0 | 6.24 |
| 3 | 59kg | IND | MANISHA | 4 | 21:00 | 30-8 | 16-1 | 4.80 |
| 4 | 76kg | UKR | ALPYEYEVA Anastasiya | 4 | 17:39 | 33-11 | 15-2 | 4.50 |
| 5 | 65kg | RUS | KASABIEVA Alina | 4 | 18:08 | 34-7 | 14-2 | 4.49 |
| 6 | 68kg | CHN | LONG Jia | 4 | 18:05 | 31-5 | 14-2 | 4.44 |
| 7 | 62kg | USA | NWACHUKWU Adaugo | 4 | 19:37 | 38-14 | 14-3 | 3.97 |
| 8 | 53kg | JPN | KIYOOKA Moe | 4 | 24:00 | 30-3 | 12-2 | 3.63 |
| 9 | 72kg | CHN | LI Zelu | 4 | 20:27 | 23-9 | 14-3 | 3.43 |
| 10 | 55kg | USA | LEYDECKER Everest | 4 | 21:55 | 16-4 | 14-3 | 3.30 |
Note: TP is the total of technical points scored, and CP is the total of classification points earned through the manner of each win. MSW is calculated from the bout-by-bout records in the official UWW data and rounded to two decimal places. For one of Susaki Yui’s bouts, her quarterfinal (bout number 365), the official data has no match time, so we calculated using the 5:37 reported by Wrestling Spirits.
Key Takeaways
1. No. 1 is China’s Hong Kexin at 57kg: MSW 7.66
China’s HONG Kexin finished first with an MSW of 7.66, about 1.4 points ahead of No. 2 Susaki Yui (6.24). Across four bouts she scored 41 technical points and conceded none, with a CP line of 16-0, and all four bouts ended in technical superiority (VSU). Her four bouts lasted 11 minutes 12 seconds in total. In the final she beat Japan’s Nagamoto Sena 10-0 by technical superiority in 3:30.
2. Susaki Yui ranks second at 6.24
Japan’s Susaki Yui took second place with an MSW of 6.24, made up of a WQ of 2.24 and a CPdiff of 4.00. Across five bouts she scored 44 technical points and conceded none, with a CP line of 20-0, and she won the gold medal without giving up a single point. Her first three bouts ended in technical superiority, her semifinal was a 9-0 decision, and her final was a fall at 2:14 (5-0).
3. Kiyooka Moe ranks 8th of 10 at 3.63
Kiyooka’s MSW of 3.63 is made up of a WQ of 1.13 and a CPdiff of 2.50.
All four of her bouts went the full six minutes and ended in decisions (two VPO1 and two VPO). Her total time of 24:00 is the longest among the 10 gold medalists. She gave up only 3 technical points in four bouts (30-3).
MSW is a metric that rewards winning by big margins in short time. It does nothing to diminish what Kiyooka accomplished: she won four six-minute bouts in a row and stood on top of the world.
4. Gold medals by country: China 3, Japan 2, USA 2
China won three of the 10 weight classes (57, 68 and 72kg), Japan two (50 and 53kg) and the United States two (55 and 62kg). India (59kg), Ukraine (76kg) and Russia (65kg) each won one.
5. Eight of the 10 finals went to a decision
Eight of the 10 finals went the full six minutes and were decided on points (VPO or VPO1). The only exceptions were Susaki’s fall at 50kg (2:14) and Hong’s technical-superiority win at 57kg (3:30). Three finals were decided by a single point: 12-11 at 62kg, and 4-3 at 68kg and at 72kg.

Team Japan Results
Japan sent 10 wrestlers and won medals in seven of the 10 weight classes. Scores list the Japanese wrestler’s points first.

- 53kg, KIYOOKA Moe (gold): All four of her bouts were decisions, and she beat YEPEZ GUZMAN (ECU) 6-0 in the final.
- 55kg, HARADA Nagisa (bronze): She won the round of 16 by 10-0 technical superiority and the quarterfinal by a 3-0 fall at 3:44. She lost the semifinal 1-6 to LEYDECKER (USA), then won her bronze-medal match with a 10-0 fall over BLAYVAS (GER) at 4:10.

- 59kg, YAMAGUCHI Natsuki: She lost her qualification bout (first round) 0-5 to MAMMADOVA (AZE). Because MAMMADOVA did not reach the final, YAMAGUCHI did not get a place in the repechage.
- 62kg, OZAKI Nonoka (silver): She won the round of 16 by 10-0 technical superiority (1:34), then took the quarterfinal 4-1 and the semifinal 2-1 on points. She lost the final 11-12 to NWACHUKWU (USA), a single-point margin.
- 65kg, IKEHATA Nana (bronze): She beat MIRACLE (USA) by a 10-1 fall at 5:32 in the round of 16. She lost the quarterfinal 4-6 to RINGACI (MDA) by fall at 4:52, but won the repechage 6-2 against RAJNITA (IND) and her bronze-medal match 9-0 against TUVSHINJARGAL (MGL).

Closing
Japan took seven medals in women’s freestyle at the 2026 World Championships: two gold, two silver and three bronze. Susaki Yui ranks second by MSW at 6.24 after winning the gold medal without conceding a point in five bouts. Kiyooka Moe ranks eighth at 3.63, having won all four of her bouts on points, and that does not change the fact that she is a world champion.
MSW is one yardstick for understanding the substance of a win. We hope you will use it not to decide who is better, but to learn how each bout was won.
Let’s keep cheering on Team Japan!
