Mt.FUJI100 (Ultra-Trail Mt. Fuji) course maps and aid stations

The three long races in the foothills of Mount Fuji range from a 38.5 km loop around Fujiyoshida to a 165 km run from Shizuoka round to the Fuji Five Lakes.

April 23 to 25, 2027 Fujiyoshida, Yamanashi, Japan

Mt.FUJI100 started in 2012 as Ultra-Trail Mt. Fuji, or UTMF. The 2027 race is the 15th edition, and its FUJI100mi and ASUMI40k count toward the World Trail Majors.

The FUJI100mi starts on Friday evening at Fuji-san Kodomo no Kuni, in Fuji City on the Shizuoka side of the mountain. It runs west to Fujinomiya, north past Lake Shoji, then east past Lake Yamanaka before it finishes at the stadium in Fuji Hokuroku Park, Fujiyoshida. The KAI70k and ASUMI40k start and finish at that stadium on Saturday: the KAI70k heads out to Oshino and Lake Yamanaka, and the ASUMI40k loops the hills around Fujiyoshida.

The race rules make the GPX course, open on your phone, part of the mandatory kit. A map you've downloaded before the start does that job, and GPS shows where you are on it with or without a signal.

You start in one of three waves, at 5:00, 5:15 or 5:30 PM on Friday, about 700 runners in each, and everyone has to finish by 2:30 PM Sunday. That gives the first wave 45 hours 30 minutes and the last 45 hours. The first night takes you west to Fujinomiya, and the 26.6 km from there to Fumoto is the longest stretch without an aid station.

Kumamoriyama, 1,574 m, rises between Fujinomiya and Fumoto, and Shakushiyama, 1,597 m, between Nijumagari Pass and Fujiyoshida. Poles are allowed on trial in 2027. Pack them in your drop bag, which waits at Oshino, and carry them from there to the finish, except on some sections inside the national park where they're banned. The 2027 aid station chart isn't out yet, so the kilometers here are from the 2026 chart, when the course was the same 165.3 km through the same eight numbered aid stations.

The KAI70k starts at 2:00 PM Saturday and you have 21 hours, until 11:00 AM Sunday, so you run through the night. It follows the last part of the 100 mile course, through Oshino, Yamanakako Kirara, Nijumagari Pass and Fujiyoshida, and passes Shakushiyama, 1,597 m, between Nijumagari Pass and Fujiyoshida. The last leg, from Fujiyoshida back to the stadium, was 18.6 km in 2026.

The 2027 course is listed at 67.9 km and 2,917 m of climbing, a little shorter than 2026's 68.6 km. The aid station kilometers here are from the 2026 chart.

The ASUMI40k starts at noon on Saturday and closes at 9:30 PM, a 9 hour 30 minute limit. There's one aid station, in Fujiyoshida at 19.7 km, and then 18.8 km of hills back to the stadium, so carry enough to eat and drink for both halves.

Getting an entry

To enter you need a finish in an ITRA race with enough points, run in the two years before general entry opens. The FUJI100mi needs one race of 4 points or two of 3, the KAI70k one of 2, and the ASUMI40k one of 1. You must be 18 on race day.

General entry for 2027 runs from November 2 to 15, 2026, with a lottery if a race is oversubscribed. Results come out on December 1 and you pay by December 15. The top 100 finishers of the 2026 FUJI100mi and elite runners get priority entry from October 19. Donation entries, which cost more and support the Fuji Hakone Izu Trail Support association, are first come, first served: 100 for the FUJI100mi and 75 for each of the others.

Once you've paid, there are no refunds or transfers. Bring a photo ID, like a passport, to pick up your bib.

Getting to Fujiyoshida

The highway bus from Busta Shinjuku in Tokyo to Fuji-Q Highland takes about 1 hour 40 minutes.

There's no public transport to the FUJI100mi start at Kodomo no Kuni, so the organizer runs a bus there from Fuji Hokuroku Park on Friday. Parking at Kodomo no Kuni is free, but you can't leave a car there overnight. At the finish there's no runner parking: buy a parking ticket in advance (sales open in late January 2027) for Fuji-san Parking or the Fuji-Q Highland Conifer Forest lot, then take the shuttle. Camping and sleeping in cars are banned at every race car park.

Crewing

Only FUJI100mi runners can have crew, and only at Fumoto, Shojiko, Oshino and Yamanakako Kirara. Crews need a supporter pass: there are 500, by lottery, with applications from January 5 to 12, 2027. One supporter per runner is allowed in the support area, with one bag of about 70 liters.

Supporters can't run alongside you, so there's no pacing. Crews can't drive to or cheer at Fujinomiya, Nijumagari Pass or Fujiyoshida. Each crew point has free supporter parking, but no shuttle runs between them. Supporters can't park at the finish either: they park at Conifer Forest and ride the shuttle.

Weather and kit

April in Kawaguchiko averages a high of 16.1°C and a low of 3.7°C, by the Japan Meteorological Agency's 1991 to 2020 normals. The organizer's own figures for Yamanakako on April 25, 2022 to 2026, average about 7.5°C at 3 AM and 17°C at 3 PM. The rules warn that a rescue on the FUJI100mi or KAI70k can take six hours or more, so carry enough to wait in cold wind and rain.

In the FUJI100mi and KAI70k, the mandatory kit includes the GPX course on your phone, two lights of at least 80 lumens with spare batteries, a waterproof hooded jacket, a warm layer, gloves and a hat, and at least 1 liter of water whenever you leave an aid station. Bring a cup of 150 cc or more: aid stations have no paper cups.

Yes. It was first run in 2012 as Ultra-Trail Mt. Fuji (UTMF) and now goes by Mt.FUJI100, with the 100 miler called the FUJI100mi. It was cancelled in 2020 and 2021.

How do you get into Mt.FUJI100?

Earn the ITRA points for your race (4 for the FUJI100mi, or two races of 3; 2 for the KAI70k; 1 for the ASUMI40k), then enter between November 2 and 15, 2026. If a race gets more entries than places, there is a lottery, with results on December 1.

Is Mt.FUJI100 a Western States qualifier?

The organizer lists the 2027 FUJI100mi as a qualifying race for the 2028 Western States Endurance Run.

Can you use poles or a pacer at Mt.FUJI100?

There's no pacing: supporters can't run alongside you. Poles are allowed in the FUJI100mi on trial from 2027, only from Oshino to the finish, and not in some national park sections. You send them to Oshino in your drop bag.

Where can crews meet runners at Mt.FUJI100?

Only in the FUJI100mi, at Fumoto, Shojiko, Oshino and Yamanakako Kirara, and only with a supporter pass from the lottery. The KAI70k and ASUMI40k have no crew support.
