Kosgei Runs Fastest-Ever Marathon in Asia, Tadese Repeats, 4 New NR, and 5 Qualify for Olympic Trials at Tokyo Marathon

Conditions weren't fantastic at the Tokyo Marathon , a bit too warm and sunny, a bit too windy, a lot too much cedar pollen in the air, but it was still a record-breaking day. Except for a race-morning DNS from men's NR holder Tomoki Suzuki there weren't any surprises in the wheelchair races, where world record holders Catherine Debrunner and Marcel Hug of Switzerland scored solo wins, Debrunner outgunning training partner and all-time #2 Eden Rainbow-Cooper by 4 minutes and Hug winning by 7 minutes in 1:21:09. The women's marathon was a slow burner, starting behind target pace on track for 2:17:00 at 5 km but ramping up all the way to the finish. CR holder and 2-time defending champ Sutume Asefa Kebede and 2022 champion / former WR holder Brigid Kosgei stayed side-by-side the entire way, shadowed by a pack of Ethiopians that dwindled down to just Bertukan Welde . The projected finish got closer and closer to Sutume's 2:15:55 CR, then past it and into 2:14 te...

Tokyo Marathon Preview

The Tokyo Marathon kicks off the 2026 Abbott World Marathon Majors this Sunday. The forecast is looking pretty good, maybe a bit on the warm side but not like last year or even last weekend in Osaka , and with quality fields in all 4 races there's a decent chance we'll see some fast times on Tokyo's borderline record-eligible downhill course. As usual, JRN's Brett Larner will host Nippon TV's international broadcast on local affiliates in 115 countries worldwide starting at 9:00 a.m. local time Sunday. Details on where to watch the broadcast here . A live leaderboard will be posted here on race morning. In the wheelchair races Switzerland's Catherine Debrunner and Japan's Tomoki Suzuki both broke the Tokyo course records last year and are back for more this year. Debrunner could get a race out of British athlete Eden Rainbow-Cooper who she beat by just 1 second in Berlin 3 years ago, and if they go the whole way there could be another new CR. Suzuki w...

Japanese hopes pretty much go to all-time #7 Ai Hosoda , 2:20:31 in Berlin 2024 but who announced this month that she is retiring after Tokyo despite having qualified for the 2028 Olympic marathon trials with her 2:23:27 for 6th in Sydney last year. Other internationals include Canadian Malindi Elmore , American Sara Hall , a big Chinese group led by Yuyu Xia , Poland's Aleksandra Brzezińska and Australian Vanessa Wilson . The men's race has 5 of last year's top 1...

photo © 2025 Victah Sailer/Photo Run, all rights reserved On Jan. 8 the Edion women's corporate team announced that Ai Hosoda , 30, will retire at the end of March this year. The Tokyo Marathon will be her last race. At Nagano Higashi H.S. Hosoda ran in the National High School Ekiden her 2nd and 3rd years.

Instead of the Olympics, Hosoda ran the 2024 Ber...

JRN's 10 Most-Read Stories of 2025

It's been a busy year, and a record-breaking one that kicked off with a Hakone Ekiden CR by Aoyama Gakuin University and ended with a new men's marathon NR from Suguru Osako . JRN's 10-most read stories of 2025: Tokyo World Championships to Leave Final Decision on Going Ahead in Heat to World Athletics - Aug. 25 After fears of hot conditions were used as a justification to move the Tokyo Olympics marathons to Sapporo, concern was high about the conditions at September's Tokyo World Championships. Ultimately, though, it wasn't much of an issue, with longer distance events being moved slightly earlier in the mornings on which they were scheduled.

Local Reporter Otawa, 23, Breaks Ohtawara Marathon CR

The Ohtawara Marathon and 10 km took place Nov. 23 at DI Stadium in Ohtawara, Tochigi. 2803 people started the marathon at 10:00 a.m., with 2354 people finishing for a finisher rate of 84.0%. The race has a cutoff time of 4 hours, and all participants are able to use special drink tables. Most years there is a headwind blowing from the mountains of Nasu in the 2nd half of the race, but this year there was almost no wind and cloudy skies. Itto Otawa , a 23-year-old Tochigi local, won the men's marathon in a 2:13:04 course record. Otawa ran this year's Hakone Ekiden for Senshu University , placing 15th on the Ninth Stage. After graduating in March he was hired by the Shimotsuke Newspaper in Tochigi, where he works as a reporter. In August he ran a PB of 2:16:29 at the Hokkaido Marathon. "At work I'm mainly in charge of the Nikko beat," Otawa said. "My goal in Ohtawara this time was to break the course record. I've run a PB every time so far in the marathon...

From the Sidelines to 6th in Sydney - Meet Masato Arao

photo © 2025 Victah Sailer/PhotoRun, all rights reserved Last weekend's Sydney Marathon featured one breakthrough performance that was kind of low in the mix. Running his first marathon outside Japan, 25-year-old Masato Arao negative split a 2:07:42 PB, moving up fast over the last 10 km to pass Eliud Kipchoge and finish 6th. With the Sydney course estimated to be about 2 minutes slow with tough hills in the early going, that meant Arao's run was about equal in quality to all-time Japanese #5, the only better marathon by a Japanese man outside Japan being Yohei Ikeda 's 2:05:12 for 6th in Berlin last fall. It was a pretty amazing breakthrough for someone who never made his college team's starting varsity lineup and a year ago was working full-time in his hometown and running for fun. Born and raised way up north in Yamagata, Arao showed a bit of promise at Sakata Minami H.S. , running the First Stage at the National High School Ekiden his first year in 2016 and maki...

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...

Putting It All On the Line - Tokyo Marathon 2025

If there was one consistent theme through all 4 races at the Tokyo Marathon this year it was risk. With temperatures nearing 20˚ and sunny conditions in the forecast pacing plans audaciously called for 2:01 for the lead men and 2:12 for the lead women, with the next 3 groups on both sides all slated for very ambitious times. The men's wheelchair race kicked things off, 2024 Tokyo winner and NR holder Tomoki Suzuki going after his own NR completely solo and coming up with a 1:19:14 CR that saw him beat 2nd place by over 11 minutes. The women's race was a CR-pace showdown between Paris Paralympics gold and bronze medalists Catherine Debrunner of Switzerland and Susannah Scaroni of the U.S.A. that saw them locked together until 40 km. Debrunner had that something else that makes her the world record holder, throwing down to open 32 seconds on Scaroni over the last 2 km, both breaking the CR but Debrunner getting the win in a stellar 1:35:56. The women's marathon was a comp...
