Fukushima Town Seikan Tunnel Museum

The Fukushima Town Seikan Tunnel Museum documents the construction of the undersea tunnel linking Honshu and Hokkaido through original machinery, tools, and technical records from different building phases. The facility shows how this tunnel was planned and built, revealing the challenges engineers faced during the project.

Tunnel boring began in the 1970s and required decades of intense work until the connection opened in 1988. The museum was later established to preserve this remarkable achievement and the stories of workers who labored on the project.

The museum reveals how this tunnel transformed connections between the two main islands and shaped the region's identity. Visitors experience the pride locals take in this engineering achievement and understand its role in Japan's modern development.

The site is well-positioned and easy to reach, with clear signage on the grounds. The building spans multiple levels, so visitors should wear comfortable shoes and allow realistic time to explore all exhibition areas.

Visitors can descend into a reconstructed tunnel section and experience the depth and confinement of the original work. This walkable replica provides genuine insight into the conditions workers faced daily.
