Regarded as one of Japan’s most scenic railways, the Tadami Line carries passengers across Aizu, the westernmost region of Fukushima Prefecture. This 84-mile (135km) railway is packed with spectacular landmarks, including Tsurugajo Castle, a 1384-built fortress destroyed during the 1868 Boshin War then rebuilt in the 1960s. There’s also Enzoji temple, a serene trackside masterpiece that's over 1,300 years old, and of course, the Tadami River.
