Mt. Adatara, an active volcano in Fukushima that is counted as one of Japan's 100 Famous Mountains
An active volcano whose activity continues to be observed today
Mount Adatara is an active volcano in Fukushima Prefecture that has been beloved by many people, having appeared in the ancient Manyoshu and Takamura Kotaro's "Chieko Sho." Located on the southern side of Bandai-Asahi National Park, it has also been selected as one of Japan's 100 Famous Mountains and Utsukushima's 100 Famous Mountains. Phreatic eruptions were observed about 100 years ago, and even after the Heisei era began, constant monitoring has been carried out due to the release of volcanic gases and increased geothermal activity

With its relatively gentle slopes, this mountain is recommended even for beginner climbers.
Mount Adatara is 1,700 meters above sea level, with multiple peaks stretching for approximately 9 kilometers from this point. Climbing the mountain reveals a variety of scenery, including craters and rock faces, and visitors can enjoy the abundance of flowers and plants. Above all, the views from the summit are spectacular, with a 360-degree panoramic view that delights climbers. There are trailheads to the mountain, including the Okudake Trailhead, Shiozawa Trailhead, Ishimushiro Trailhead, Noji Onsen Trailhead, and Yokomuki Onsen Trailhead, and several trails lead from these trailheads. Near all of these trailheads are hot spring resorts, including Shiozawa Onsen, Dake Onsen, Numajiri Onsen, Okudake Onsen, Noji Onsen, and Yokomuki Onsen. These are popular places to soothe your tired body after a long day of hiking.
The Adatara Valley Nature Trail is also popular, and originates just below the ridge of Mt. Adatara. It runs along the upstream Harase River, commonly known as the Karasu River, at an altitude of approximately 950-1,000m. The trail is approximately 1km long and takes about an hour to walk
Some of the hiking trails have ropeways, making it easy for beginners and those who just want to enjoy the scenery. The autumn foliage season is so popular that special services are even run. The trees, colored red and yellow, look like a carpet. The peak of the autumn leaves begins near the summit in late September, and slowly trickles down to the base by early November
In addition, you can enjoy alpine plants from spring to summer, and ski at Adatara Kogen Ski Resort in winter. Tourists visit this mountain all year round, making it one of the most visited mountains in the prefecture, alongside Mount Bandai
