Know Your Japanese Runners in Boston

The withdrawal of Kentaro Nakamoto (Yasukawa Denki), Japan's best championship marathoner of the modern era, from the Boston Marathon field with a stress fracture is a blow to what would have been the best Japanese contingent in Boston in decades.

Yuki Kawauchi (Saitama Pref. Gov't) leads the way, arriving in Boston off wins in his last four marathons:

2:10:03, Hofu Yomiuri Marathon, 12/17/17
2:18:59 CR, Marshfield New Year's Day Marathon, 1/1/18
2:11:46 CR, Kitakyushu Marathon, 2/18/18
2:14:12, Wan Jin Shi Marathon, 3/18/18

Kawauchi hopes to at least equal Suguru Osako's top 3 placing in last year's Boston, his optimism growing as the weather forecast gets worse.

Naoki Okamoto (Chugoku Denryoku) runs for what was once Japan's most successful corporate team in the marathon, his best of 2:12:31 coming 6 years ago at Lake Biwa and his fastest recent time a 2:13:33 in Tokyo last year. Okamoto earned a place in Boston by winning February's tough and hilly Ome 30 km in 1:33:09.

A high-volume marathoner like Kawauchi, Kansuke Morihashi (Raffine) won January's Katsuta Marathon in 2:16:51 to earn an invite to Boston. A month later he followed up with a PB of 2:14:25 at the Tokyo Marathon, jogging the Seoul Marathon three weeks after that in a fun run effort.

Topping the women's side is another idiosyncratic high-volume marathoner, Hiroko Yoshitomi (Memolead). Yoshitomi won the hilly Katsuta Marathon in January in 2:33:56, the second-fastest winning time in event history, then came back a week later to smash the Beppu-Oita Mainichi Marathon course record with a 2:33:00 win. A week after that she took 9th in the National Corporate Half Marathon Championships in 1:13:58. Two weeks later in Tokyo she ran 2:30:16 for 6th, cutting over a minute off her five-year-old PB. Three weeks after that, a 2:33:57 win in her hometown Saga Sakura Marathon.

Ome women's winner Maki Ashi (Kyudenko) rounds out the Japanese lineup in her marathon debut at age 24. A 1:11:12 half marathoner, Ashi ran 1:44:14 in Ome to seal up a trip to Boston. Interestingly, joining her in Boston as her coach is the just-retired Kazuhiro Maeda, a longtime rival of Kawauchi's who was part of the 2013 Moscow World Championships team alongside both Kawauchi and Nakamoto.

Chepkirui Over Sato Again to Win 2nd-Straight Nagoya Women's Marathon, Chen Breaks Malaysian NR (updated)

This year's Nagoya Women's Marathon felt like a changing of the guard, with some the bigger domestic names over the last few years fading early and a lot of newer faces stepping up with quality debuts or second marathons. The front group was set to be paced for 2:20 flat with the 2nd group at 2:23:30 to hit the auto-qualifying time for the 2027 MGC Race, Japan's L.A. Olympics marathon trials race in Nagoya. Up front things went out OK, but after a 33:10 split at 10 km Ayuko Suzuki , 2:21:22 here 2 years ago, lost touch, ultimately finishing 23rd in 2:33:28. Windy conditions started to play with pacers' ability to keep things steady and the pace slowed majorly over the next 10 km, but even with a 34:05 second 10 km there were big-name casualties. 2024 Nagoya winner Yuka Ando was next to drop, ending up 17th in 2:30:32. NR holder Honami Maeda was next, followed quickly by Bahraini Kenyan Eunice Chumba and debuting Wakana Kabasawa . Maeda faded to 21st in 2:31:21, whil...

Nagoya Women's Marathon Preview and Streaming (updated)

Japan's winter marathon season of 6 major races in 7-straight weekends wraps up Sunday with the world's largest women-only marathon, the Nagoya Women's Marathon . The weather is looking pretty good, 6˚ at the start rising to 10˚ by the finish and sunny skies, but a moderate 7 m/s NW wind means a headwind finish that might impact the potential for some fast times. Official streaming kicks off at 9:00 a.m. local time. Live results will be here . Sheila Chepkirui won last year in 2:20:40, breaking away from Sayaka Sato and Eunice Chebichii Chumba at 30 km and hanging on for the win. Sato negative split a 2:20:59 PB for 2nd, Chumba fading to 3rd in 2:21:36. All 3 are back this time, but they have pretty serious competition from Aynalem Desta , 2:17:37 in Amsterdam last fall, and Selly Chepyego Kaptich , 2:20:03 in Barcelona 2023. And of course, Japanese NR holder Honami Maeda . Maeda ran 2:18:59 at the Osaka International Women's Marathon in 2024 to make the Paris Oly...

16 Women and 26 Men on the Current Olympic Trials Qualifier List

Last weekend's Nagoya Women's Marathon and the Tokyo Marathon the weekend before brought the main part of the first year of qualification for the Marathon Grand Championship Race, Japan's L.A. Olympics marathon trials to be held in Nagoya in October, 2027, to an end. There are still a few races like the Nagano Marathon and overseas World Athletics platinum label races this season where people might qualify, but for the most part we're not likely to see many new additions until August's Hokkaido Marathon, where the qualifying period opened last year. As of right now 16 women and 26 men have qualified, although the first woman to make the cut, Ai Hosoda , announced that she was retiring after Tokyo earlier this month. Out of the 16 women to have qualified so far, Mikuni Yada is the fastest with her 2:19:57 debut at Osaka Women's in January. Including Hosoda that makes 2 qualifiers for the Edion corporate team, but Daihatsu has the biggest share of the field so ...
