Karasawa-koya is the smaller, more “homey” mountain hut in the Karasawa Cirque area—often chosen by hikers who want the Karasawa atmosphere but prefer a quieter, more intimate hut than the large-scale Karasawa Hütte nearby. It sits on a south-facing slope with a wide view over the cirque and is a key staging point for routes toward the Hotaka peaks.

Karasawa Hütte is one of the most famous mountain huts in Japan, sitting in the heart of the Karasawa Cirque beneath the Hotaka peaks. It’s a true high-traffic alpine hub: a base for autumn foliage trips, a staging point for routes toward Okuhotaka / Kitahotaka, and the center of one of Japan’s largest and most organized mountain campsites.

Nishiho Sanso is a major ridge-access mountain hut above the Shinhotaka Ropeway, widely known for being one of the few huts in the Northern Japanese Alps that operates year-round. It’s a practical base for hikers heading to Maruyama and the more serious ridge terrain toward Nishi-Hotaka-dake, and it’s also a key entry point for winter mountain experience—only for properly equipped, experienced parties.

Kita-hotaka-koya is a legendary high-ridge mountain hut perched just below the summit of Mt. Kita-Hotaka-dake on the main Hotaka ridgeline. It’s famous for its extreme position above sheer drops and for being a key staging point for advanced ridge travel—especially the Daikiretto traverse toward Yari.
