01 / History

What makes Tokyo different

The modern Tokyo Marathon began in 2007, formed by merging two older races, the original Tokyo Marathon and the Tokyo International Marathon, into one event. It drew roughly 95,000 applicants for 31,000 spots in its first year alone, competitive from the very start. In 2013, Tokyo joined Boston, London, Berlin, Chicago, and New York to complete what became known as the six World Marathon Majors, the newest member of a series that had otherwise been fixed for years.

Short answer

The Tokyo Marathon is the newest of the original six World Marathon Majors, joining the series in 2013. It runs every March point to point from Shinjuku to Marunouchi near Tokyo Station, on a flat, fast course, and remains one of the hardest majors to enter, with well over 300,000 applications each year for around 37,500 spots.

03 / Course & training

A course built to tell a story

Tokyo's route was deliberately designed to move through the city's past, present, and future. It starts near the futuristic skyscrapers of Shinjuku, passes through the electronics district of Akihabara, runs by the historic Sensoji Temple in Asakusa, and finishes in Marunouchi, the modern business district near the Imperial Palace and Tokyo Station. A 2017 to 2018 course revision made the layout flatter and genuinely record-eligible, and it has produced fast times ever since despite typically cold, early-March conditions.

Famous winners and defining moments

Tadese Takele won the 2026 edition in a tactical sprint finish, 2:03:37, ahead of Geoffrey Toroitich and Alexander Mutiso Munyao, his second consecutive Tokyo title. Only one other man, Birhanu Legese in 2019 and 2020, has ever repeated as Tokyo champion, which places Takele's back-to-back win among the race's rarest achievements. On the women's side, Brigid Kosgei ran 2:14:29 in the same 2026 edition, a new course record, a minute faster than the previous mark. Marcel Hug and Catherine Debrunner won the wheelchair races.

Tokyo's reputation is built as much on scarcity as on speed. With acceptance rates typically in the single digits to low double digits, simply being selected to run is, for most applicants, a longer process than training for the race itself.

How to train for Tokyo

Tokyo asks less of your legs than a hilly course like Boston or New York, and more of your preparation for cold weather and travel.

Rehearse your cold-weather race morning

Early March in Tokyo is typically cold. Practice your warm-up and start-corral routine in genuinely cold training conditions beforehand, including a layering plan you can shed easily, so race morning is not the first time you have managed the cold before a hard effort.

Train for sustained goal-pace endurance

Like Berlin and Chicago, Tokyo's flat profile rewards even, disciplined pacing more than hill strength. Marathon-pace tempo runs and controlled long runs matter more here than terrain-specific work.

Plan for travel and jet lag if you're coming from far away

International runners, especially from Europe or the Americas, are covering serious distance to get here. Build in extra days to adjust your sleep schedule before race day, rather than arriving and racing on a body that thinks it is a different time zone entirely.

Cold-weather and travel logistics matter, but they sit on top of real fitness, not instead of it. Build your aerobic base and anchor your week around the long run well before race week.

Tokyo Marathon FAQ

When is the Tokyo Marathon?

The Tokyo Marathon runs every year in early March, point to point from Shinjuku to the Marunouchi business district near Tokyo Station. It became the newest of the World Marathon Majors' original six races in 2013.

How hard is it to get into the Tokyo Marathon?

Very. Tokyo receives well over 300,000 applications each year for around 37,500 general entry spots, an acceptance rate typically between 7 and 13 percent, making it one of the hardest majors to enter by lottery alone.

Is the Tokyo Marathon course flat and fast?

Yes. Since a 2017-2018 course revision, Tokyo has been a largely flat, record-eligible course, capable of producing genuinely fast times despite typically cold early-March temperatures.

How should I prepare for Tokyo's cold race-day weather?

Early March in Tokyo is typically cold, so warm-up logistics and layering strategy matter more here than at most other majors. Plan disposable warm layers for the start corral and rehearse your race-morning routine in cold conditions during training, not for the first time on race day.
