Welcome to Avid Adventures Japan!


Avid Adventures Japan works with the race organizers of some of Japan's premier trail running races to help them introduce their race to a broader international audience.


Depending on the race, we provide some or all of the following services:

 - Overseas racer registration process

 - Communications with racers/media in English

 - Racer Support Packages that include accommodations and transportation to/from the race



Here's our race lineup for 2017!

All of these races are extremely popular in Japan and sell out within hours/days. Trail running is a wonderful way to come and explore the beautiful nature and local culture of Japan and we're excited to be able to open up opportunities for racers coming from overseas to participate in these amazing races. If you have any questions regarding the race, registrations and/or the packages, please feel free to contact us anytime. We look forward to making your trip to Japan a very memorable one!



September 16-18, 2017   (Nagano & Niigata Prefectures)

Registration starts on:  Sunday, June 11, 2017 at 21:00 JST (Japan Standard Time)


The Shinetsu Five Mountains Trail race is one of the most popular ultra-trail running races in Japan that has sold out in minutes every single year. This year is going to be extra special though because they've now added a new 100 mile (160km+) category in addition to the original 110km race!


As the SFMT does not have an English website, they've asked us to provide an official translation on our Avid website. As the official SFMT "English" desk, we will also be responding to any questions you might have about the race in English so feel free to drop us a line anytime! Overseas racers can also sign up for the race through this website (we have 30 slots available on a first come first serve basis).

December 10, 2017   (Shizuoka Prefecture, Izu Peninsula)

Registration starts on:  Sunday, June 1, 2017 at 12:00 noon JST (Japan Standard Time)



The Izu Trail Journey (ITJ) is yet another popular and stunning race that takes racers along a very scenic route in Izu Peninsula, southwest of Tokyo. This year, we've translated all the race details and registration information on the official race website (www.izutrailjourney.com  ← Click on the "ENGLISH" button on the upper right hand corner)

Race accommodation packages will also be available through Avid. 

We will be posting this info by mid-June!


 (Yamanashi & Shizuoka Prefectures)



The UTMF is one of Japan's premier ultra-trail running races that takes racers around Mt. Fuji. There are two races - the UTMF (165km) & STY (72km) and we've been providing racer support packages every year since the start of the race. Unfortunately, the race has been postponed this year (no 2017 race) and the next edition is expected to happen at the end of April 2018.


 We will provide updates as soon as we receive official announcements about the new race dates.
