Bandai-Azuma Skyline

Abukuma Cave is one of the largest limestone caverns in eastern Japan, formed over 80 million years and stretching more than 3 kilometres beneath the hills of central Fukushima. Approximately 600 metres are open to the public along a well-lit standard course, where stalactites, stalagmites, and flowstone formations of extraordinary delicacy fill illuminated chambers. An additional adventure course — requiring a helmet and crawling through narrow passages — takes visitors into sections rarely seen in Japanese show caves. The cave maintains a year-round temperature of around 15°C, making it refreshingly cool in summer and pleasantly mild in winter.

A unique double-helix wooden temple built in 1796 whose ascending and descending ramps spiral around a central axis without ever crossing — 33 Kannon statues line the route, allowing a complete pilgrimage without retracing steps.

Aquamarine Fukushima is one of Japan's most conceptually distinctive aquariums, built around the theme of the Kuroshio and Oyashio ocean currents that collide off the Fukushima coast, creating one of the world's most biologically rich seas. The centrepiece is a vast tunnel tank through which visitors walk beneath schools of tuna, rays, and sharks. Unlike conventional aquariums, Aquamarine also incorporates rice paddy exhibits, river ecosystems, and a beachside outdoor zone, reflecting the connection between land and sea that defines the Hamadori coast. Hands-on programs include touch pools, fishing experiences, and behind-the-scenes tours, making it one of the most engaging aquariums in Tohoku.
