The Tokyo Marathon has just concluded, and the 2027 Tokyo Marathon is already on the calendar. Next year will mark the 20th edition of the Tokyo Marathon — expected to be a grand, special edition. The registration schedule for next year has been confirmed: charity runner registration goes first, opening June 24–July 9, 2026. Specific details will be announced on April 15, 2026. Next are registrations for ONE TOKYO members and semi-elite runners; both will run July 31–August 13, 2026. Finally, general registration is set for August 14–28, 2026. Remember to set your alarm so you don't miss registration. Do you want to take part in the commemorative 2027 Tokyo Marathon? #Tokyo Marathon#marathon#GrandSlam#TrailRunningBigBang
