Hotaka-dake-sanso is a major high-alpine mountain hut sitting at Shiradashi Col, the saddle between Mt. Okuhotaka-dake (3,190 m) and Mt. Karasawa-dake (3,110 m). Because it’s positioned right on the main ridge spine, it functions as a core staging base for summit pushes, ridge traverses, and serious Hotaka-range itineraries—especially for parties linking Karasawa to the Okuhotaka / Hotaka ridge.

• Hut Overview

  • Location: Shiradashi Col (between Okuhotaka-dake and Karasawa-dake), on the Nagano–Gifu prefecture border

  • Altitude: 2,996 m

  • Type: Mountain hut + tent site

  • Capacity: ~250 people (this year operated as ~210 people, reservation-based)

  • Season: Apr 27 – Nov 4 (overnight stays until Nov 3)

  • Tent site: often listed around ~30 tents (policy/limits can vary by season)

  • Operator: Hotaka-dake-sanso (official site)

• Access & Approaches

  This is trekking terrain, not casual hiking. Even in summer, the hut stresses that all routes are “trekking routes” and require proper mountain footwear and competence.

  Common access patterns include:

  • Kamikochi → Yokoo → Karasawa → ridge climb to Shiradashi Col (classic Karasawa-side access)

  • Shinhotaka / Gifu side approaches for traverse parties linking the Hida side
    Route choice and timing matter because the last sections are steep, rocky, and highly weather-exposed.

• Facilities & Comfort

  Despite the altitude, this is a large, well-run “infrastructure hut,” but logistics are still strict.

  • Structured lodging with multiple meal-plan options (details and pricing published by the operator)

  • Drinking water: the hut states water is free for overnight guests, and is also available for campers who bring containers to the hut (important because the tent site is separate)

  • Large-hut rhythm: fixed schedules, early arrivals preferred, and capacity control during peak periods (reservation-based operations)

• Food & Atmosphere

  Expect a busy ridge-hub atmosphere:

  • Early dinner, early lights-out

  • Pre-dawn departures for summit attempts and safe ridge crossings

  • A high proportion of experienced hikers and traverse parties, especially in stable weather windows.

• Routes & Alpine Context

  Hotaka-dake-sanso is strategically used for:

  • Mt. Okuhotaka-dake summit pushes (Japan’s 3rd-highest peak)

  • Ridge traverses across the Hotaka spine (including demanding sections)

  • Linking Karasawa staging with higher Hotaka objectives in a single, controllable itinerary.

• When to Go

  • Best season: July–September for the most reliable “snow-free” conditions (weather can still change fast at ~3,000 m).

  • Shoulder season (spring / late autumn) can involve winter-like hazards—confirm conditions and operating rules directly with the hut before committing.

• Who Is This Hut For

  • Strong hikers targeting Okuhotaka and Hotaka ridge objectives

  • Multi-day trekkers linking Karasawa to the ridge network

  • Parties who want a high, efficient base with controlled logistics (reservations, schedules, water planning)

Why This Hut Is Worth Visiting

At 2,996 m, Hotaka-dake-sanso is “infrastructure in the right place”: it sits exactly where serious Hotaka itineraries converge, making summit timing and ridge travel significantly more realistic—especially when weather and fatigue margins are tight.
