Koyaban: Life in the Yatsugatake Mountains The Movie | How to Watch Online Free & Streaming on U-NEXT, Amazon Prime Video & ABEMA

Koyaban: Living in Yatsugatake The Movie — where can we watch it? The release is on January 9, 2026! I’ll thoroughly investigate whether there’s a way to watch it for free! But first, I need a snack; I’m already missing the mountain air!

What is a “koyaban” (mountain lodge keeper)?

Koyaban refers to people who stay long-term or seasonally in mountain huts, responsible for maintaining and managing the huts, assisting visitors, and ensuring safety. Japanese mountain culture has long relied on them; by operating huts that serve as bases for climbers, they also contribute to local nature conservation and sharing up-to-date information about the mountains. The documentary film “Koyaban: Living in Yatsugatake The Movie” is especially appealing in the way it portrays the relationship between nature and people through the lives and duties of these lodge keepers.

The role and history of koyaban

Traditionally, koyaban have handled meal preparation, bedding, inspection of trails and surrounding facilities, and seasonal maintenance work. They also shoulder important safety responsibilities, such as keeping track of weather information, providing first response in the event of an accident, and giving advice to climbers. Historically, as mountain huts were developed alongside the growth of mountaineering and mountain worship, this became a specialized role and has continued to this day, shaped by the local culture and customs of each region.

Characteristics of life as a koyaban in Yatsugatake

Yatsugatake is a mountain range whose scenery changes distinctly with each season, and a notable characteristic of the work there is the heavy workload that varies by season—dealing with winter snowfall, maintenance after the spring thaw, and the busy summer hiking season. Because the climbers who visit range from complete beginners to seasoned veterans, koyaban must meet a wide variety of needs, which requires strong communication skills and deep knowledge of the area. The film is particularly noteworthy for being shot entirely in Yatsugatake, following the life and work of koyaban with visually stunning images across all four seasons.

For documentaries and more independent films, SVOD additions may be delayed or limited to certain platforms (such as U-NEXT or ABEMA).
