[Fukushima City, Fukushima Prefecture] 1,600 meters above sea level. Jododaira Astronomical Observatory, closest to the stars in Japan

``Jododaira Observatory'' is a public observatory located in ``Jododaira,'' located at an altitude of approximately 1,600m, halfway between the Plateau Highway and the Bandai Azuma Skyline in Fukushima City, Fukushima Prefecture. It is the highest observatory in Japan that is open to the public.

Joudodaira Observatory is open from early April to early November (when the Bandai Azuma Skyline is passable), and is open every Wednesday and Saturday at night from mid-May to the end of October (unless there is bad weather). Admission is free.


Impressed by the number of stars that you can't usually see in the city

During the day, Jodo-daira has many attractions such as Azuma Kofuji, Jodo-daira Wetland, Issai Kyozan, Goshikinuma (commonly known as Witch's Eye), and Kamanuma. Don't miss the countless stars that fill the sky at night. The sight of the Milky Way drifting through the sky is especially impressive.

The large telescope installed at the Jododaira Observatory allows you to see things that are invisible to the naked eye. The main telescope of Joudodaira Observatory is a large telescope that combines a 40cm diameter reflecting telescope and a 15cm diameter refracting telescope, allowing you to observe faint stars up to magnitude 14.8. There are also several small telescopes and binoculars installed, including a 25cm aperture reflecting telescope and a 15cm aperture binocular telescope, allowing you to clearly see the moon's craters, Saturn's rings, Jupiter's stripes and moons. The museum director and staff will adjust the telescope to the position of the star you want to see depending on the season, so you won't miss anything.

``Jododaira'' is a plateau area that stretches over an area at an altitude of approximately 1,600 meters in the Azuma Mountain Range in western Fukushima Prefecture, and shows different expressions depending on the season. Approximately 70 minutes from Fukushima City, the capital of Fukushima Prefecture, by Bandai Azuma Skyline, the center has the Jodo-daira Visitor Center, Jodo-daira Rest House, Jodo-daira Observatory, and a large parking lot, making it a great base for walking around the area and visiting viewpoints. It becomes.

The surrounding area is part of Bandai-Asahi National Park, and is home to the beautiful Azuma Kofuji, the rugged mountain surface of Mt. Ichikkyo, the Joudodaira Wetland where alpine plants bloom with pretty flowers, and the beautiful water known as the witch's eyes. There is a wide variety of scenery, including Goshikinuma, a crater lake that celebrates the ancient world. A walking path has been established from the Jododaira Visitor Center, and it is a heavenly paradise where you can easily enjoy highland exploration and trekking during the green season. However, in the winter, everything is closed due to snow.

"Azuma Kofuji" is a Mt. Fuji-shaped mountain with an altitude of 1,707m, and there is a large crater at the top. It stands right next to the Jodo-daira parking lot and is a symbol of Jodo-daira. The difference in elevation from Jododaira to the summit is approximately 100m, and it takes about 10 minutes to climb the stairs from the side of the parking lot to reach the summit. The crater is approximately 500m in diameter and 70m deep, and there is a walking path that allows you to go around it in about an hour.


Active volcanoes “Isshu Kyozan” and “Witch’s Eye”

``Issatsukyozan'' is an active volcano with an altitude of 1,949m that rises to the northwest of the Jododaira parking lot. The desolate mountain surface gives an eerie feeling. Eruptive activity at Mt. Ikkei began about 300,000 years ago, and the explosion that formed Azuma-Kofuji and the surrounding swamps occurred between 4,900 and 7,000 years ago.

The walking course to Mt. Isshukyo takes about 40 minutes from the Jododaira Visitor Center to Sugadaira at the foot of the mountain, and from Sugadaira to the summit, it is a trekking course with an elevation difference of about 370m. There are many dangerous places to climb to the top of the mountain, and there are areas where sulfur dioxide gas is emitted, so it is necessary to wear proper mountaineering clothing and trekking shoes. Please refrain from wearing light clothing or taking unreasonable walks during bad weather.

It gets its name because its shape resembles a sickle. This nature walk course has an elevation difference of about 190m from Jododaira, and is about 5.1km round trip from the visitor center, taking less than 2 hours.

Joudodaira campsite equipped with an administration building and toilets

``Jododaira Campsite'' is located in Usagidaira, about a 10-minute walk from the Jododaira Visitor Center. There is an administration building, restrooms, and parking lot (Usadaira parking lot), but it is not an auto campsite, so you cannot drive there. Also, camping equipment such as tents, food, and fuel are not available for rent, so be sure to prepare them in advance. Fireworks and campfires are prohibited, and it is good manners to take trash home with you. Nighttime temperatures are more than 10 degrees lower than in the flatlands, so you need to take precautions against the cold.
