Takatsuma-yama (高妻山, 2,353 m) is the highest peak of the Togakushi range, straddling the prefectural border between Nagano City (Nagano Prefecture) and Myoko City (Niigata Prefecture). It is a long, strenuous day climb on a route shaped by centuries of Shugendo ascetic practice: the standard approach passes a sequence of small stone Buddhist statues, each marking a stage of the mountain's religious count, before the final pull to a sharp rocky summit. The combination of a sacred, statue-marked ascent, deep forest, and a genuinely demanding day makes Takatsuma-yama one of the more distinctive Hyakumeizan in the Joshinetsu region.
Why Fukada Chose Takatsuma-yama
Takatsuma-yama is one of Kyuya Fukada's hundred famous mountains. Fukada did not number or rank his peaks; the order in Nihon Hyakumeizan runs roughly north to south as a geographic sequence, not a league table. Takatsuma sits in that northern Joshinetsu group alongside the better-known Togakushi-yama nearby.
What sets the mountain apart is the religious character of the climb itself — an ascetic route still marked, station by station, by old stone statues set into the ridge. The ascent works through that sacred layer of the mountain before delivering a steep, purely physical finish to the summit.

The Routes
Two main routes lead to the summit, both starting from the Togakushi Campground area. There are no mountain huts on either route, so both are full day climbs.
Ichifudo (Daido-sawa) Route — via Goji-zo-san
Grade: Advanced
- Distance: ~13.8 km round trip
- Time: about 4 h 50 m ascent, 3 h 20 m descent (roughly 8 hours moving)
- Character: From Togakushi Campground (~1,160–1,200 m) the trail climbs the Daido-sawa gully to the Ichifudo emergency shelter, then follows the ridge over Goji-zo-san to the summit. The ascent passes a sequence of stone Buddhist statues marking the ascetic stages — Ichifudo, Nishaka, Sammonju, Shifugen, Goji-zo, Rokumiroku, Shichikannon, Hachiyakushi, Kuseishi, and Juamida — after which the summit is reached.
- Safety: The Daido-sawa section has fixed-chain passages (Namedaki, Obi-iwa, Fudodaki) and runs up a gully that can flood and become dangerous after rain.
Miroku-one Shindo — via Rokumiroku
Grade: Advanced
- Time: roughly 3 h 30 m ascent, 3 h descent
- Character: A ridge route (opened October 2001) that joins the main ridge at the Rokumiroku station. It avoids the Daido-sawa gully and its chains, making it a drier alternative, though still a steep, sustained climb to the summit.
Getting There
From Nagano Station (Shinkansen):
Take the Hokuriku Shinkansen to Nagano Station, then the Alpico [70] Togakushi Line bus to its terminus at Togakushi Campground (戸隠キャンプ場) — the trailhead — which takes about 75 minutes (roughly 1 h 15 m). A seasonal sightseeing limited-express bus also runs from Nagano Station (Zenkoji Exit) to Togakushi Campground.
By car:
Hikers' parking is at the Togakushi Campground entrance along Prefectural Route 36 (県道36号).
Mountain Huts
There are no staffed mountain huts on either route. The only shelter is the Ichifudo emergency hut (一不動避難小屋), which is unmanned. Takatsuma-yama is a day-hike-only peak — plan your timing accordingly and do not count on overnight facilities on the mountain.
Water: Sources on the trail are limited. The main one is the Seki-shimizu spring near the start of the Ichifudo route. Carry enough water for a long day.
Flora and Wildlife
Asiatic black bears (ツキノワグマ): This is the correct bear species for the Togakushi area (Honshu has only Asiatic black bears). Carry a bear bell, make noise on the forested lower approach, and store food carefully.
Ridge flora: The summit ridge is known for colonies of yellow lady's-slipper (キバナノアツモリソウ), Shirane-aoi (シラネアオイ), and Ichiyoran (イチヨウラン) — a distinctive draw for botanically minded hikers in season.
Summit views: From the summit and ridge you can see Yakeyama, Hiuchi, Myoko-san, and Kurohime-yama, with the more distant Yatsugatake and Asama ranges and the Northern Alps beyond; on clear days, Mt. Fuji is visible past Yatsugatake.
Seasonal Guide
Through May: Residual snow makes the upper mountain dangerous. Twelve-point crampons and an ice axe are needed in this period; spring conditions are for experienced winter mountaineers only.
June onward: The recommended climbing season begins. Some snow patches may linger on the upper mountain early in the month.
July – August: Peak season.
September – October: Generally the best conditions, with autumn colour in mid-October.
Practical Tips for Foreign Visitors
File a climbing plan: A climbing-plan form (tozan-todoke / 登山届) is mandatory under Nagano Prefecture's mountain-safety ordinance. Submit one before you start (Nagano Prefecture, and Niigata Prefecture police for the border area).
Plan for a full day with no bailout huts: With around 8 hours of moving time and no staffed shelter, start early and turn back if you fall behind schedule.
Mind the gully after rain: On the Ichifudo (Daido-sawa) route, the gully and its chain sections can flood and become hazardous after heavy rain. If rain is forecast, consider the Miroku-one Shindo ridge route or postpone.
Togakushi soba: The Togakushi area is one of Japan's most famous soba-producing regions, and a bowl of cold togakushi-soba near the campground or shrine area is a fitting end to a long climb.
Frequently Asked Questions
Is Takatsuma-yama a day hike or an overnight climb?
It is a day-hike-only peak. There are no staffed mountain huts on either route — the only shelter is the unmanned Ichifudo emergency hut — so plan to be off the mountain the same day. The standard route involves roughly 8 hours of moving time, so start early.
Can I reach the trailhead without a car?
Yes. Take the Hokuriku Shinkansen to Nagano Station, then the Alpico Togakushi Line bus to its terminus at Togakushi Campground, the trailhead, which takes about 75 minutes. A seasonal sightseeing limited-express bus also runs from Nagano Station (Zenkoji Exit) to the same stop.
Do I need to file a climbing plan?
Yes. A climbing-plan form (tozan-todoke) is mandatory under Nagano Prefecture's mountain-safety ordinance, and you submit it before you start. Because the summit straddles the prefectural border, this covers Nagano Prefecture and Niigata Prefecture police for the border area.
When is the best time to climb, and when does the snow clear?
The recommended season runs June through October, with September and October generally offering the best conditions and autumn colour in mid-October. Residual snow makes the upper mountain dangerous through May, requiring twelve-point crampons and an ice axe, and some snow patches may linger early in June.
What kind of bear lives here and how do I prepare?
Asiatic black bears, the only bear species on Honshu, inhabit the Togakushi area. Carry a bear bell, make noise on the forested lower approach, and store food carefully.
