Mount Nyūkasa Optical Observatory

Mount Nyūkasa Optical Observatory is an astronomical facility situated at 1,816 meters elevation in the Akaishi Mountains, outfitted with modern telescopes and precision instruments for celestial observation. The location takes advantage of high altitude and minimal light pollution to enable accurate measurements of distant objects in space.

The facility was founded in 1990 and became an important center for astronomical research in Japan. Its strategic location in the central Alps enabled significant contributions to space exploration research over the following decades.

Scientists and researchers gather at this facility to study celestial phenomena, continuing Japan's long tradition of astronomical observation and space research.

The site sits in a mountainous region, so access requires travel on mountain roads and weather can shift quickly. Visitors should prepare for high altitude conditions and bring warm clothing and sturdy footwear.

The observatory sits near the Fujimi Panorama Resort, offering visitors access to alpine landscapes and seasonal plants alongside scientific facilities. This combination makes the location a meeting point between research and nature in the mountains.
