Jododaira Observatory - Tohoku's Finest Starry Sky Experience at 1,575m Elevation

Overview

Jododaira Observatory is an astronomical observation facility located at approximately 1,575 meters elevation along the Bandai-Asahi Skyline near Fukushima City, Fukushima Prefecture. Surrounded by Azuma-kobushi Mountain and Ichigyakei Mountain within a volcanic high plateau, it boasts some of Tohoku's finest astronomical observation conditions.

Using a 40-centimeter reflector telescope mounted inside a 5.5-meter-diameter dome, you can observe nebulae, star clusters, planets, and other celestial objects. Combined with its high elevation and absence of major light sources nearby, the Milky Way is distinctly visible even to the naked eye.

Observation Environment

The 1,575-meter elevation is tremendously attractive to astronomy enthusiasts in the Kanto and Tohoku regions. Compared to lowland areas, the atmospheric layer is thinner with less water vapor and dust, making stars shine noticeably brighter.

Although the observatory is about 40 kilometers from Fukushima's city center, climbing the curves of the Bandai-Asahi Skyline progressively blocks the city's light. The observatory surroundings maintain Bortle scale class 2 darkness, with favorable nights revealing stars magnitude 6 and brighter.

Facilities and Equipment

The observatory's main telescope is a 40-centimeter reflector, with professional staff providing guided explanations of seasonal celestial objects. The adjacent visitor center offers learning opportunities about Azuma Mountain's nature and volcanic activity.

The rest house provides light meals and comfortable break areas. Restroom facilities are available, ensuring comfort during extended observation sessions.

Access and Important Notes

The Bandai-Asahi Skyline operates from mid-April through mid-November, closing in winter. Toll is free. From Fukushima-Nishi IC to the skyline entrance takes about 30 minutes, with an additional ~10 minutes to the observatory.

Access may be restricted due to volcanic activity, so confirm latest information before visiting. Given the high elevation, nights can drop below 10°C even in summer—bring warm clothing.
