The JR Tadami Line is a 135 km railway connecting Aizu-Wakamatsu Station in Fukushima Prefecture with Koide Station in Niigata Prefecture. Although National Route 252, which runs parallel to the line, opened in 1973, the surrounding area is known as one of Japan’s heaviest snowfall regions. During the winter, the mountain pass on the prefectural border (Rokujūrigoe) is closed to traffic, making the Tadami Line a crucial means of transportation that has long supported the local community.

The First Tadami River Bridge is among the most popular spots along the line. Deciding how to balance the deep canyon, the iron bridge, the train, and the river’s surface in a single frame is a challenge that inspires even those who aren't professional photographers. Another must-see photogenic location is the Third Tadami River Bridge, known for its mystical river mists. After enjoying the vibrant "wardrobe change" of nature in autumn, visitors can experience the serene silver world of snow-covered winter, the pastel colors of spring flowers celebrating the long-awaited season, and the refreshing, soft greenery that coats the fields and forests in summer. The Tadami Line truly offers unique charms throughout the four seasons.

On March 11, 2011, Fukushima Prefecture suffered unprecedented damage from the Great East Japan Earthquake and the subsequent nuclear accident. Adding to this tragedy, the Niigata-Fukushima torrential rains struck in July 2011, inflicting severe damage on the Tadami Line, including collapsed tracks from landslides and the loss of iron bridges. The section between Aizu-Kawaguchi and Tadami Stations was particularly devastated; the No. 5, 6, and 7 bridges spanning the Tadami River were washed away, and significant embankment collapses occurred near the No. 8 Tadami River Bridge. While JR East’s dedicated restoration efforts allowed most of the line to resume operations shortly after, the severely damaged section between Aizu-Kawaguchi and Tadami relied on substitute bus services until September 30, 2022.
