Mt. Tsubakuro (2,763 m) is a very popular destination in the Northern Japanese Alps due to its unique appearance and beautiful alpine flora. Its well-maintained trails, convenient rest areas and lodges, and beautiful scenery make it a must-hike spot in Nagano. Daytrips to the peak are possible, but hikers can enjoy a much more relaxed two-day hike if they stay at the expansive Enzanso lodge on top of the ridgeline.

Mt. Tsubakuro at a Glance

The Trail to Mt. Tsubakuro

The trailhead begins from Nakabusa Onsen at an altitude of 1,462m. The trail continues through the forest for a majority of the climb before breaking through the tree line for the last hour or so. Rest areas are spaced evenly throughout the hike, with four bench areas in the woods followed by the Kassen-goya hut and the Enzanso mountain lodge above the tree line. From the lodge, the peak is approximately 40 minutes.

Roundtrip, the hike takes about 9.5 hours (6 hours up, 3.5 hours down), with an altitude difference of 1,300m. Most people stay the night at the Enzanso lodge, but it is possible to hike in a single day with the proper level of fitness.

This hike’s amazing views begin around the fourth bench. From here, you can see the Yatsugatake mountain range and Mt. Fuji standing proudly in the distance. From higher still, you can see the Hakuba mountains and Mt. Tsurugi as well. Once you reach Enzanso, the landscape opens up and you can enjoy panoramic views of the Northern Alps as well as Mt. Tsubakuro’s magnificent features.

Most striking is the peak’s vivid collage of grey, green and white. The ridgeline is covered in granite outcroppings, verdant shrubbery and swaths of bleached gravel. Viewed closer, the rocks take on unique and recognizable shapes. Along the trail you can find a lounging gorilla, a breaching dolphin, and a pair of glasses pointed at Mt. Yari. At your feet, small, pink komakusa flowers.

And from the top of Mt. Tsubakuro, one can see the most beautiful view of all: the tan ridgeline of Omote-Ginza zigzagging along towards the rest of the Northern Alps. On the right day, the clouds lap the gravelly slopes of the mountains, curling and twisting like the great waves off Kanagawa, and the distant Enzanso lodge appears to float in the sky.

Mt. Tsubakuro’s scenery is breathtaking and is a must-hike peak for any climbing enthusiast. Its safe trails, convenient rest areas, and fully-stocked mountain lodge make it a great climb for families as well. Enjoy unparalleled views atop the Roof of Japan!

Access to the Trailhead

By Train/Bus

Nakabusa Onsen can be reached by bus or taxi from JR Hotaka Station on the Oito line. From the Station, the ride to Nakabusa is approximately 60 minutes long. One-way bus fare is 1,700 yen, and one-way taxi fare 7,500 yen. You can see the bus schedule in Japanese here.

By Car

For drivers, there are three parking lots in the vicinity of the trailhead as well, and they have a total capacity of 120 cars. Because they fill up very quickly, you may want to park at the Ariakesan Shrine mountain climber's parking lot (“Ariakesan Jinja Tozansha Senyo Chushajo,” 有明山神社登山者専用駐車場) and take a bus (see bus details here) or taxi from there instead (around 6,200 yen).

Accommodation and Hot Springs

Nakabusa Onsen

Nakabusa’s hot springs are rich sources of minerals and bubble out from the ground at a scalding 90°C.

Yama-no-Takohei

The Yama-no-Takohei hotel and hot spring is located about halfway between Hotaka Station and the Tsubakuro trailhead.
