Karasawa Breaks T11 5000 m World Record - Weekend Track Roundup

Four out of five corporate regional championship meets went off as schedule this weekend, with the 51st Hokuriku Region meet in Ishikawa the only one to cancel amid the latest COVID-19 wave hitting Japan.

The 63rd East Japan Region meet in Saitama was the biggest and fastest of those that did happen. The biggest news was in the T11-T13 men's 5000 m, where T11-class Kenya Karasawa (GSWC) won in 15:09.94, going a second and a half under the previous world record for his class. Sitonki Kiprono (Komori Corp.) turned in the only sub-28 men's 10000 m of the weekend, winning Saturday's A-heat in 27:47.69. Justus Soget (Honda) was likewise the only one to go sub-3:40 for 1500 m, winning Saturday's A-heat in 3:39:12. Soget doubled to win Sunday's men's 5000 m A-heat in 13:29.43 going close to 55 seconds for the final lap and ending up the only man under 13:30 for the weekend.

Pauline Kamulu (Route Inn Hotels) won the East Japan women's 10000 m in 32:15.27 on Saturday. Tabitha Njeri Kamau (Mitsui Sumitomo Kaijo) won Sunday's 5000 m A-heat in 15:17.94 in a close race that saw the top four finish within less than 0.9 seconds of each other. Ririka Hironaka (Japan Post) set a meet record 8:56.65 to win the 3000 m A-heat, the fastest 3000 m of the weekend. Cynthia Mbaire (Hitachi) won the 1500 m A-heat in 4:13.45, leading Naomi Muthoni Kariuki (Univ. Ent.) and Chikako Mori (Sekisui Kagaku) under 4:15. Mori doubled Sunday in the 3000 mSC, running a 9:50.67 meet record for the win.

At the 65th Chubu Region meet in Gifu, Rodgers Chumo Kwemoi (Aisan Kogyo) took the men's 10000 m A-heat in 28:09.99 by almost 10 seconds. His teammates Philemon Kiplagat and Kosei Yamaguchi went 1-2 in Saturday's 3000 mSC, Kiplagat in a meet record 8:26.50, then did it again in Sunday's 5000 m, Kiplagat running 13:31.10 and Yamaguchi 13:31.24. Kazuki Kawamura (Toenec) won the 1500 m A-heat in 3:42.67.

The women's races were mostly low-key, with Naoko Koizumi (Denso) winning the 10000 m in 34:06.71 and Momoka Kawaguchi (Toyota Jidoshokki) the 5000 m in 15:45.63. Kawaguchi's teammates Nozomi Tanaka and Yume Goto won the 3000 m and 1500 m in 8:58.54 and 4:14.29, with Ayano Ikeuchi (Denso) soloing a 10:21.79 meet record to win the 3000 mSC.

At the 65th Kansai Region meet in Osaka, two weeks after securing her place on the Tokyo Olympics 10000 m squad Yuka Ando (Wacoal) won the distance double, taking Friday's 10000 m in 31:58.55 and Sunday's 5000 m in 15:30.30. Olympic marathoner Mao Ichiyama (Wacoal) was 3rd in the 10000 m and 2nd in the 5000 m just a week and a half after running a PB 1:08:28 to win the Olympic marathon test event half marathon.

In Kansai it was the men's races that were relatively low-key, Katsuhiko Suzuki (SGH Group) winning the 10000 m in 28:45.19, Ayumu Kobayashi (NTT Nishi Nihon) the 5000 m in 13:44.16, Yuki Ishii (NTT Nishi Nihon) the 1500 m in 3:45.30, and Jun Shinoto (Sanyo Tokushu Seiko) the 3000 mSC in 8:48.13.

Corporate regional action wraps up next weekend with the 64th Kyushu Region meet.

Chepkirui Wins Nagoya Women's Marathon

Heavy-duty favorite Sheila Chepkirui took the win at Sunday's Nagoya Women's Marathon , pulling away after 30 km to cruise in for 1st in 2:20:40. Erratic pacing early saw the first and second groups only seconds apart for much of the first half of the race, the top group slower than planned and the 2nd group a bit ahead of schedule. At halfway in 1:10:37 the front group included Chepkirui, #2-ranked Ruti Aga and last year's runner-up Eunice Chumba , and Japanese contingent Sayaka Sato , Rika Kaseda , Natsuki Omori and Mao Uesugi . Omori was the first to drop, then Uesugi, then Aga, who ultimately dropped out before 30 km. When the pacers stopped at 30 km Chepkirui made a move that dropped Kaseda and strung out Chumba and Sato behind her, but all four came back together once before another surge put Kaseda away for good. As Chepkirui inched away Sato and Chumba passed each other repeatedly, and Chumba could only watch as the top Japanese runner got away from her again thi...

Who's Running Tokyo Worlds?

The Japanese marathon teams will be the most prestigious ones to be on for September's Tokyo World Championships, and with Sunday's Nagoya Women's Marathon the window for Japanese athletes to get onto the JAAF's shortlist closed. Who's on it? The final decision won't be made until Mar. 26, but let's look through the selection criteria and see who's guaranteed, who's pretty likely, and who has a chance. 1. Marathon medalists at the Paris Olympics - There weren't any, so nobody makes the team this way. Akira Akasaki (Kyudenko) and Yuka Suzuki (Daiichi Seimei) were the top placers, both of them running PBs in the Olympics to finish 6th. You'd think that would count for something a year later, but you'd think wrong. 2. JMC Series IV Champions - The top point scorers in the Japan Marathon Championship Series IV, which ran from April, 2023 to March, 2025, earn places on the marathon teams along with cash prizes. For women that's Yuka ...

Tokyo Marathon Top Japanese Man Tsubasa Ichiyama Works 4 Days a Week, Walked On in College

38,000 people ran the 2025 Tokyo Marathon . Every runner had their own story, but one of the most special was Tsubasa Ichiyama (Sunbelx). Despite being on almost nobody's radar, he outran some of the best in the country to finish as the top Japanese man. Ichiyama ran most of the race in the 3rd pace group, going through halfway in 1:02:44 and 30 km in 1:29:13. When the pacers stopped, he showed what he could really do. "I'm not good at downhills, so in the first part it was hard to run smoothly," he said at the post-race press conference. "But after the downhill part ended I got into my rhythm, and I think that helped me over the 2nd half." After dropping Asian Games gold medalist Hiroto Inoue (Mitsubishi Juko) and others, he quickly bore down on the Japanese athletes who had gone out faster in the 2nd pace group. Overtaking Paris Olympics 6th placer Akira Akasaki (Kyudenko) and Yuhei Urano (Fujitsu), at 39.8 km he caught all-time Japanese #2 man Yohei I...
