Race Entries

Races in Japan usually close entry at least a month beforehand, often much longer. They generally do not have race day entry and race organizers are not willing to make special exceptions for foreigners. If you are coming to Japan for, say, a business trip in two weeks, it is not possible to enter a race. If you are making longer-range plans then it may be possible to find a suitable event using the following services:

Samurai Running Japan is a long-standing entry service that focuses on smaller races to help overseas visitors "experience the 'real' Japan."  Along with entry it assists with accommodations and transportation.

Launched in September, 2015, Runnet Japan is an English-language branch of Runnet, Japan's dominant online entry service, catering to the international community.  The number of races offered on Runnet Japan is still limited but constantly expanding.

Other entry services like Sports Entry, TecNet and the new Sportsnavi Do still offer only Japanese-language and domestic address service, but with swelling numbers of international runners at races across Japan they are bound to get in on the action soon.

How can I find out when some races are? I am likely moving to Japan in September and would love to do a 10km there end of September or in October. I however am having trouble finding a run (co-ed). If you could advise me on where to look, or if you know of any runs I would appreciate your assistance.

Brett, I lived in Chitose, Hokkaido from 1997-2000. It took me from October to April to sort out the race entry system. But in the winter there were no races locally anyway. Do they still use the post office system for race registration or is everything on line now?
I know travel in Japan is expensive, but I can heartily recommend the Hokkaido Marathon, Chitose JAL, and Okhotsk. But the prettiest course is Toya Ko in May.

Hi,

Im currently living in Ishikawa Ken and a friend of mine as well as myself have been considering entering ourselves into the kumejima marathon in Okinawa.

I have tried to research how to enter online and have so far only succeeded in finding out the date of said race and the closing date for entrees.

Any help you could possibly give me would be a great help!! Also, if you know of any running clubs in Ishikawa Ken that would also be appreciated!!

Hi Brett

Thanks for your tips, really helpful.

I am very keen to enter the Niigata Marathon on 11 October 2015. I am wondering whether you are able to kindly provide any tips on how to enter or any sites I can go to for entry.

Cheers

Hi Brett,
thank you for providing your help :)

We are coming to visit Japan in May and I was thinking of running a Half-Marathon during my visit.

I was doing some research by myself and could only find 1 races in May:Gifu City.

Do you know if the Fuji Susono Half Marathon takes place this year?

Are there any other runs?

thanks in advance,

gilles

Japan's London World Championships Marathon Squad Arrives Back Home

The six members of Japan's men's and women's marathon teams at the ongoing London World Championships returned to Tokyo's Haneda Airport on Aug. 9. Decked out in the official team suit, Japanese team captain and at 9th the top-placing Japanese marathoner in London Yuki Kawauchi (Saitama Pref. Gov't) spoke to the media.

Having declared pre-race his intention to withdraw from consideration for future Japanese National Team positions, post-race Kawauchi showed no change in that intent. With regard to his future plans, his motivation as a competitor likewise remaining unchanged, Kawauchi indicated that he will run Decmeber's Fukuoka International Marathon,where his 3rd-place overall finish last year earned him his place in London. "In Fukuoka I want to break my PB and run 2:07," he said. "There are things I want to accomplish besides being on the National Team."

Kawauchi revealed that his next marathon will be September's Oslo Marathon, whe…

Silver and Bronze - Summary of Japanese Performances at 2017 London World Championships

Thanks to a last-minute rush Japan walked away from the London World Championships with a passable haul. The JAAF judges performance in terms of medals and top 8 finishes. Up to Saturday, only one Japanese athlete had met either, 18-year-old sprinter Abdul Hakim Sani Brown finishing 7th in the men's 200 m final as the first Japanese man to make a 200 m final at Worlds since 2003. Three other Japanese athletes had scored top 10 placings, Yuki Kawauchi and Kentaro Nakamoto in the men's marathon and Ayuko Suzuki in the women's 10000 m, but under the JAAF's criteria these were not viewed as success.


Saturday's men's 4x100 m final brought the first Japanese medal of the Championships, with Japan following up on its Rio Olympics silver with a bronze, its first-ever Worlds medal in the discipline. Sunday morning brought Japan's best-ever showing in the men's 50 km race walk, Rio bronze medalist Hirooki Arai moving up to silver, Kai Kobayashi taking bronze wit…

London World Championships - Day Nine Japanese Results

Following up on its silver medal at the Rio Olympics, the Japanese men's 4x100 m relay squad delivered the first Japanese medal of the London World Championships as it took bronze behind hosts Great Britain and U.S.A. Swapping in alternate Kenji Fujimitsu for ailing anchor Aska Cambridge in the final, the team featured only two starting members of the Rio lineup. Lead runner Shuhei Tada, a student at Kwansei Gakuin University who burst onto the scene in May, again proved himself the best new development in Japanese men's sprinting with a fast start. Rio members Shota Iizuka and Yoshihide Kiryu did their bits on second and third to keep Japan even with Jamaica in 3rd before Fujimitsu delivered the goods.

With bronze at the Beijing Olympics and silver in Rio last year it was Japan's first-ever World Championships men's 4x100 m relay medal. At age Fujimitsu may not make it to the 2020 Tokyo Olympics, but with Cambridge, 200 m finalist Abdul Hakim Sani Brown and Rio team …
