The Tokyo Marathon 2021 is one of the six Abbott World Marathon Majors. This is a fantastic marathon in an exciting city. The marathon course winds through Tokyo’s central districts and takes in many of the city’s major sights. It is a hugely popular and superbly organised international event with the total number of runners capped at 37,500. Over 300,000 runners apply to run every year so it is a massively over-subscribed event. As the official Irish International Travel Partner for the Tokyo Marathon 2021, we offer guaranteed entry as part of our tour package.
