Mizunami Earth Corridor

Mizunami Earth Corridor is a natural history museum built underground within a civic park, featuring a 240-meter passageway. Visitors encounter fossils, mineral specimens, and rock formations displayed in exhibition zones that illustrate Earth's geological story from its formation onward.

The structure originally served as an underground factory during the Pacific War era. It was later repurposed and opened as an educational museum in 1993, transforming a wartime facility into a public learning space.

The museum serves as a learning center where visitors walk through underground passages to discover how Earth has developed over vast periods of time. This hands-on approach to geology makes the subject accessible to people of all ages visiting from the local area.

The underground location maintains cool and humid conditions throughout, so visitors should wear appropriate clothing for a subterranean environment. The pathway through the exhibition corridor is straightforward to navigate, though comfortable footwear helps when walking the full distance.

The underground space was originally built as a wartime industrial facility and now naturally preserves exhibits under stable geological conditions. Few museums can claim such a transformation from military infrastructure to peaceful scientific education.
