Deep Japan Ultra confirmed for 26-28 June 2026

Niigata has become one of Asia Trail Master’s permanent race regions over the past ten years and we are happy this tradition continues also in 2026. Deep Japan Ultra is confirmed as an ATM qualifier for Season XI’s Championship with its usual two Grandmaster Quest race distances: 100 miles and 80km.

Organised by well-known runner Hiroaki Matsunaga, the event takes place in Niigata Prefecture, roughly 2-3 hours by shinkansen northwest of Tokyo. There’s also a few international flights to Niigata city directly. Visitors not familiar with Japan will experience the real countryside, which often remains unexplored. The host venue is the Mount Asakusa Park. Participants should be prepared for technical mountain trails, which at higher altitudes may still be covered in snow. Especially if you sign up for the 100 miles, do not come unprepared and unfocused. This is not a race to ‘try out’ 100 miles for the first time. The 80 km category has plenty of spice and technicality as well. Those who take it seriously will be rewarded with one of Asia’s finest endurance trail runs.

Make sure you read all the requirements in terms of mandatory gear. The website - linked below - is very detailed and in English , so you can prepare in the best possible way.

Register as soon as you can, because spots are limited. Note also that there is a strict registration deadline of 28 February. Too late is really too late here. Give yourself time to plan the event, including accommodation and travel, and get yourself ready for a wonderful trail experience next June!
