Joetsu Line Loop Tunnel

Overview

Discover the Joetsu Line Loop Tunnel in Minakami, Gunma, a unique railway engineering marvel. Built in 1929, this spiral tunnel was essential for shortening the rail journey from Tokyo to Niigata by approximately four hours. Located a short walk from Yubiso Station, the tunnel allows trains to navigate steep inclines by looping within the mountain. Today, it's a registered Civil Engineering Heritage site, offering a fascinating glimpse into Japan's railway history. For the best views of the loop, ride an ascending train from Doai Station towards Yubiso, keeping an eye out on the right side. Consider visiting during daylight hours to fully appreciate the surrounding scenery.
