The following calendar lists Japanese races, mainly around Tokyo. We advise those viewing from outside Japan that: 1) Dates on the calendar that are a few months ahead may not be correct — races from the previous year are not updated until new information is available. Note that almost all races on are Sundays. 2) Japanese races have application deadlines from one to six months before the race, and most fill up quickly. 3) With the exception of the Tokyo Marathon and a few other events, Japanese race organizers are usually very domestically focused and do not provide multi-lingual support, either for application or on race day. 4) The Tokyo Marathon is at the end of February. Application for the lottery is in August. 5) We do not offer a commercial service for arranging entry. However if you contact us through the Contact page and we are able to help, we will do what we can.
