Overview (history, characteristics, attractions)
The Seikan Tunnel Memorial Museum (Sotogahama-cho, Aomori Prefecture) is a facility that introduces the construction history and technology of the Seikan Tunnel, which opened in 1988. The Seikan Tunnel is an undersea tunnel that connects Honshu (Aomori Prefecture) and Hokkaido (towards Hakodate), with a total length of approximately 53.85 km, of which approximately 23.3 km is undersea. Known as one of the world's leading undersea tunnels, it is filled with the history of the many years of work that went into its construction, as well as the technical ingenuity required to overcome the difficult geological and harsh climatic conditions at the time of its construction.
The museum clearly conveys the process leading up to the completion of the tunnel through the equipment, models, blueprints, photographs and videos used in the construction. It is not only worth seeing for those interested in civil engineering and tunnel engineering, but also as an exhibit on the modern history of the region and the lives of the people.
Highlights
- Construction history exhibit: A timeline from the start of construction to completion, along with photographs from the time and testimonial panels, allows visitors to understand the construction process.
- Model and cross-section exhibits: With cross-sectional models of tunnels and models showing the excavation mechanism, you can visually learn about the undersea structure and technologies such as ventilation and drainage.
- Actual exhibits of machine tools and components: Actual materials such as parts of used drilling equipment, concrete fragments, and bolts are often on display, which is very impressive.
- Video section: You can experience the hardships and technical innovations of the time through recorded footage of the construction and interviews.
