Daisetsuzan to Akan–Mashu 9 Day Hiking Tour

The blue crater pond on Mt Meakan in the Akan–Mashu National Park. Volcanic steam rises in the background.

Experience Hokkaido’s varied hiking and unique wildlife. This tour takes in high alpine plateaus, steaming active volcanos, clear caldera lakes and alpine wetlands home to the Hokkaido brown bear.

The Daisetsuzan National Park is the second largest national park in Japan, it covers over 2,300 square kilometres (570,000 acres) making it larger than Tokyo! The mountains that form the backbone of the park are volcanos, some still active, and include Hokkaido’s highest peaks. The rocky volcanic soil combined with harsh alpine environment creates a landscape like no other.

Established along with the Daisetsuzan National Park in 1934, the Akan–Mashu National Park is home to active volcanos and large caldera lakes surrounded by ancient forest. The area is also renowned for its onsen hot-springs thanks to the volcanic activity. Each hot spring has different qualities giving you even more reason to jump in for a soak.

Continuing along the ridgeline to Mt. Nishibetsu (800m), we admire the steep caldera cliffs rise above the lake. Next we reach our high point, Mt. Mashu (857m), where we can enjoy lunch with stunning views of the lake below before descending back to the caldera rim and continuing to the carpark, where our van is waiting.

Farewell

Our tour finishes in the morning in Abashiri. After breakfast, we check out of our accommodation. We will drop you off at either JR Abashiri train station or Abashiri Memanbetsu Airport (MMB), depending on your onward travel.

From the train station you can catch a Limited Express train to Sapporo. From the airport you can fly directly to Tokyo Haneda (HND). We will bid our farewells as you set off to your next destination in Japan. Itterashai!

What is the hiking like on this tour?

This is our most challenging hiking tour. On paper, the daily average 9km doesn’t seem much, but that misses the 600m average elevation gain and the fact that Hokkaido’s mountain trails are “rugged” to put it mildly. If you are looking for your next Japanese hike after completing the popular Kumano Kodo or Nakasendo walks, you may be in for a shock! Expect to make knee-straining steps on large rocks, navigate exposed roots and slip and slide on loose gravel, snow or mud. We will spend time hiking in the alpine, where we are exposed to the full brunt of Hokkaido’s mountain weather - which is an experience in its own right.

This is the perfect tour for hikers with experience in the alpine - think European Alps, New Zealand or the Rockies. We have time limits on some days, which means we need everyone in the group to be able to keep a steady pace all day long.

Our Around Daisetsuzan 6 Day Hiking Tour is a good alternative. It includes some of the highlights of the first half of this tour in more approachable days.

Get in touch with us if you are unsure what tour is best for you. We are happy to answer any questions you have and describe the hikes in more detail.
