About

A community for choosing your Japanese marathon.

Run in Japan is a multilingual decision-support hub for runners considering a marathon in Japan. We surface what to run, when registration is open, who's recruiting pacers and medical runners, and what to expect on race day.

What we do

Curated race selection

Filtered by overseas-friendliness, certified status, and fit (PB / travel / family). Every race links back to the official site.

Recruitment aggregation

Open pacer, medical-runner, and volunteer recruitment in one place, refreshed against official sources.

Trip + logistics context

Travel, lodging, food, and overseas entry process per race so you can plan the whole trip, not just the race.
