Ichinokoshi-sanso is a major public mountain hut on the ridgeline between Murodo and Mt. Tateyama (Oyama)—a classic staging point for summit pushes, sunrise starts, and multi-day traverses in the Tateyama–Tsurugi area. It’s designed for throughput and safety on a very busy alpine corridor, not for “lodge comfort.”

• Hut Overview

  • Location: On the main trail between Murodo Terminal and Mt. Tateyama (Oyama), Tateyama area, Toyama Prefecture, Japan

  • Altitude: 2,700 m

  • Type: Public mountain hut (Japanese alpine hut style)

  • Capacity: 130 sleeping places

  • Season (typical): late April → mid-October (varies slightly year to year)

  • Tenting: No tent site

• Access & Approaches

  This is one of the most logistically straightforward high huts in Japan thanks to the Tateyama Alpine Route access.

  • Main access: From Murodo Terminal, via the well-marked Tateyama summit trail (common “Ichinokoshi Route” stage)

  • Typical hiking time: Often used as the midpoint stop on the Murodo ↔ Oyama climb (timing depends heavily on snow season, weather, and crowding).

  • Difficulty: T2–T3 (becomes more serious in wind, fog, or early-season snow).

• Facilities & Comfort

  Operational and efficient—good infrastructure, but not “comfort amenities.”

  • Meals available during the staffed season (set hut service)

  • No bath / no shower

  • Water: managed supply (commonly listed as available/free for overnight guests)

  • Payment: cash only (no credit cards)

  • Reservations: via hut contact channels (email/phone listed on the official site)

• Food & Atmosphere

  Expect a busy, summit-driven rhythm: early dinner, early lights-out, and pre-dawn departures—especially in peak summer and during autumn foliage windows.

• Routes & Alpine Context

  Ichinokoshi-sanso is central for:

  • Mt. Tateyama (Oyama) summit day staging from Murodo

  • Linking itineraries across the Tateyama highlands and onward toward other huts in the area

• When to Go

  • Best season: July to September for the most straightforward trail conditions.

  • Shoulder season (late April–June / October) can involve winter-like conditions on the ridge; plan for cold, wind, and reduced visibility.

• Who Is This Hut For

  • Hikers aiming for Mt. Tateyama with a staged schedule

  • Multi-day trekkers linking Tateyama-area routes

  • People who want reliable public infrastructure at altitude (and can handle crowds)

Why This Hut Is Worth Visiting

At 2,700 m with 130 beds, Ichinokoshi-sanso is pure alpine infrastructure: perfectly positioned on the Tateyama summit corridor, efficient in bad-weather logistics, and ideal for early starts—especially when you want the summit experience without gambling on same-day timing from the terminal.
