Tokyo Marathon to expand participant field for 2026 race

June 23, 2025

On Monday, the Tokyo Marathon announced that it will expand its participant cap from 38,000 to 39,000 runners for the 2026 edition. Of these, 38,500 spots will be allocated to marathon participants. The remaining 500 entries will go to the 10.7K race, which starts at the same location and is reserved for youth, visually impaired athletes, transplant recipients and wheelchair racers.

If you’re looking to increase your acceptance rate, consider a charity entry. Along with a donation of roughly C$1,000, runners must pay the standard race entry fee (approx. C$315). Another guaranteed entry route is through official travel partners, which offer race bibs bundled with hotel and flight packages. These options are steep, often more than C$5,000, but give runners a hassle-free alternative to the lottery. Running Magazine
