Tokyo Marathon in Tokyo
The Tokyo Marathon debuted on February 18, 2007, uniting two earlier alternating races into a single annual event that quickly grew into one of the world's most oversubscribed marathons. Admitted to the Abbott World Marathon Majors in 2013 as its only Asian race, it now draws over 300,000 applicants annually for a field capped near 36,000, run through central Tokyo's landmark districts each February or March.
The Tokyo Marathon held its inaugural running on February 18, 2007, an event that unified two previously separate races, the Tokyo International Marathon and the Tokyo-New York Friendship International Marathon, which had alternated years rather than running as a single annual fixture.
