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.

1500 m U20 NR holder Keita Satoh (Nike Swoosh TC) is running this weekend's New Balance Fifth Avenue Mile , the first time that a Japanese man has been invited in the race's 45-year history. In university Sato had to change focus away from middle distance to the half marathon-scale lengths of the Hakone Ekiden stages, but since graduating in March and relocating to Flagstaff he has refocused on the 1500 m, going from 3:43.19 in April in his first 1500 m in almost 4 years to 3:38.30 over the course of 5 races. Fifth Avenue will be his last race before heading back to Japan for one more track 1500 m and some down time. Men's entries with best 1500 m times in last 3 years: Stefan Nillessen (NED) - 3:29.23 (2025) Flavien Szot (FRA) - 3:30.74 (2025) Oliver Hoare (AUS) - 3:31.07 (2024) Jake Heyward (GBR) - 3:31.18 (2026) Titouan Le Grix (FRA) - 3:31.46 (2026) Romain Mornet (FRA) - 3:31.62 (2025) Adam Spencer (AUS) - 3:31.83 (2026) Pieter Sisk (BEL) - 3:31.85 (2025) Gary Martin (...

Australian YouTuber Handed Lifetime Ban by Ageo City Half Marathon After Running 1:06 with Another Runner's Bib (updated)

After discussion with their race's chief JAAF referee, on Nov. 27 the organizers of the Ageo City Half Marathon handed down a lifetime ban from their event against 36-year-old Australian Matt Inglis Fox  for running the Nov. 15 race wearing the bib number of another JAAF-registered runner. The incident came to light after Fox posted on his personal Instagram account that he had run a PB of 1:06:33 and finished 203rd in Ageo with a 10 km split of 31:03, along with photos and video of himself in the race wearing a bib number beginning with 11. Fox did not appear in the results by name or in that time or place, the closest match being a 1:06:54 gross, 1:06:50 net finish time with a 31:21 10 km split for 18th place in the JAAF-registered division and 209th overall by bib number 1129, registered to a non-Japanese Tokyo-resident club runner. The club runner, Harrisson Uk , readily confirmed that he had given his bib to Fox, saying, "I gave my number to Matt. It wasn't me."...
