Japan Marathon Guide: Tokyo Marathon, Hakone Ekiden & Running Culture
Frequently Asked Questions
How do I enter the Tokyo Marathon as an international runner?
International runners apply through official overseas travel agent packages, which combine race entry with accommodation. The entry window opens around August-September for the following March race. Packages are listed on the official Tokyo Marathon website's international section. Alternatively, charitable entries are available through official charity partners — minimum fundraising amounts apply. Standard lottery entries are available to Japanese residents only.
What is the Hakone Ekiden and can tourists watch it?
The Hakone Ekiden is a 2-day university relay marathon held January 2-3, running from Tokyo to Hakone and back. It is Japan's most-watched sporting event. Spectating is completely free — simply stand anywhere along the open public road course. Key spots are relay exchange points and the dramatic mountain climb on leg 5 (January 2, reaching the peak in early afternoon). Public transportation near the course is extremely crowded on race days.
Where is the best place to run in Tokyo?
The Imperial Palace outer loop (5km) is Tokyo's most popular running route — flat, closed to cars on Sunday mornings, and used by thousands daily. Yoyogi Park offers a pleasant park circuit with less pavement. The Sumida River embankment provides a longer route from Asakusa south. Komazawa Olympic Park has a measured 2.1km loop. Most hotels in central Tokyo are within jogging distance of at least one of these options.
Are there running events in Japan besides full marathons?
Yes — Japan has thousands of races annually including 5km fun runs, 10km community races, half-marathons, trail races, and the uniquely Japanese ekiden relay format. Runnet.jp is the main registration platform (Japanese-language). Trail running is growing rapidly — races in Hokkaido, Japanese Alps, and Shikoku's 88-temple pilgrimage route attract international participants. Most entry windows open 3-6 months before the event.
What running gear brands are Japan-specific or Japan-exclusive?
Asics (from Kobe), Mizuno (Osaka), and Onitsuka Tiger (the Asics predecessor brand) are Japan-origin running brands with flagship stores and exclusive Japan editions. Special-edition Tokyo Marathon shoes from Asics are released annually and sell out quickly. Brooks and Saucony have limited distribution in Japan vs their US availability. New Balance Japan releases Japan-specific colorways. Many shoes are released in Japan 3-6 months before their international release.
