Yakehashiri International Exchange Village in Iwate, Japan — Lava Flows Meet Stars

Overview

Yakehashiri International Exchange Village is a multi-use facility at the foot of Mt. Iwate in Hachimantai, Iwate Prefecture. Within its grounds, the "Ginga Station Observatory" provides telescopic stargazing.

The Yakehashiri lava field—designated a Japanese Special Natural Monument—was formed by Mt. Iwate's 1719 eruption. Gazing at the starry sky above the black lava creates a landscape nowhere else in the world.

Observation Environment

Situated in Hachimantai's mountains, about 30 kilometers from Morioka, the area has minimal street lights, particularly to the northeast. At 560 meters elevation, clear nights reveal the Milky Way. The Mt. Iwate silhouette as a foreground makes this a famous destination for starry-sky landscape photography enthusiasts nationwide.

Facilities and Equipment

The Ginga Station observatory houses a 20cm refractor telescope. Regular evening observation sessions take place. On-site facilities include a campground, cottages, and a hot spring ("Yakehashiri-no-Yu"), allowing you to enjoy stars while staying overnight.

The campground features both grass and auto sites—a popular starry-sky camping experience.

Access

Saikon IC on the Tohoku Expressway is just 15 minutes away, excellent accessibility. About 40 minutes from central Morioka.

Stargazing Tips

The lava-flow area's entrance is the most open viewing point. Black lava reflects heat minimally, creating stable air currents—ideal observation conditions. Summer campground crowds require red-light discipline; use red filters on headlamps to show respect.
