The Tokyo Marathon Foundation has finalized the framework for next year's race, and the numbers reflect an event determined to mark its 20th edition in style. At a board meeting on June 22, organizers confirmed the 2027 race, set for March 7, will expand to 40,000 participants — the largest field in the event's history — while elite winners will compete for $170,000 each, the richest payout on the Abbott World Marathon Majors circuit.
A Bigger Field, a Bigger Prize, and New Categories for Athletes With Disabilities
The field grows from 39,000 to 40,000, making it the largest domestic marathon Japan has staged. Organizers are also introducing dedicated divisions for para-athletes and runners with disabilities, plus a permanent two-person "Duo Team" category that had previously run as a trial. The long-standing 10.7km race will be folded into the main marathon distance to make room.
Foundation chairman Tadaaki Hayano said the expanded field and record prize money are meant to deliver a genuinely world-class race, while pointing to sustainability commitments — waste reduction, environmental protection, and diversity, equity and inclusion initiatives — as central to keeping the marathon sustainable long-term.
Course Stays Familiar, but Entry Opens in Stages Starting in August
The route keeps its signature path: starting at the Tokyo Metropolitan Government Building and finishing near Tokyo Station's Gyoko-dori, passing through Suidobashi, Ueno Hirokoji, Kanda, Nihonbashi, Asakusa's Kaminarimon gate, Ryogoku, Monzen-Nakacho, Ginza, Tamachi and Hibiya. It's certified by the Japan Association of Athletics Federations and World Athletics/AIMS. Runners get seven hours to finish, wheelchair racers two-and-a-half; anyone 19 or older on race day is eligible. Entry fees are ¥19,800 domestically and $230 (about ¥37,000) overseas, both including administrative fees and tax.
Registration opens in stages from June 24, 2026: charity fundraising slots run June 24–July 9, general charity entries July 14–August 13, ONE TOKYO premium and global members July 31–August 13, and general public entry August 14–28. If applications exceed capacity, places go by lottery, prioritizing runners rejected three years running, then Tokyo residents, then the general pool.
Blue Impulse Flyover and a New Event Hub Headline the Anniversary Program
The 20th-anniversary program includes an assembly of elite runners, a premium finisher's medal, and an aerial display by the Japan Air Self-Defense Force's Blue Impulse squadron on race day. From March 5–7, 2027, organizers will open the Tokyo Marathon Square at Shinjuku Sumitomo Building's triangular plaza for press conferences and a post-race party. Other additions include a global volunteer program for overseas residents, a health-app-based finisher support system, and a Green Mileage donation program tied to environmental offsets.
Charity Network and Trade Expo Round Out the Broader Event
The foundation is partnering with 38 organizations across 40 charity programs covering sports development, environmental protection and refugee support — building on roughly ¥7 billion raised in past editions. Groups including the Sports Legacy Project, Ronald McDonald House Charities Japan, Peace Winds Japan and ACE set minimum donations from ¥100,000 to over ¥350,000, with criteria varying by group. Lottery winners can also join a carbon-offset program, contributing ¥2,600 — about ¥100 per mile run — with their entry fee.
The race needs 10,000 volunteers, with registration opening October 6, 2026. Tokyo Big Sight's South Exhibition Hall will host the Tokyo Marathon EXPO 2027 from March 4–6, one of Japan's largest running trade shows; exhibitor applications open September 1, 2026. Tokyo Metro joins as a special sponsor alongside 26 other official partners. （Related： Japan, US, South Korea Hold Fifth Trilateral Talks on North Korean Cyber Threats ｜ Latest ）
