Hirose Memorial Museum

The Hirose Memorial Museum is a biographical and mining museum in Niihama comprising a preserved residence and exhibition hall. Together they display artifacts, documents, and mining equipment that document the Besshi Copper Mine operations and the life of the family that managed it.

The museum documents how Saihei Hirose secured the Besshi Copper Mine through the Edo to Meiji transition when the government was attempting to requisition valuable assets. He also adopted modern mining techniques that improved the efficiency and scale of operations.

The former residence shows how a prominent mining family lived during Japan's rapid industrialization, mixing Japanese and Western architectural styles in their home. Visitors can observe the objects, furnishings, and spaces that reveal the daily life and values of people who shaped the region's economy.

The museum is located in a quiet area and both buildings are easily accessed on foot from each other. Plan to spend 1 to 2 hours exploring both structures and viewing the exhibits at a comfortable pace.

The museum features Japan's first mountain railway, an innovative transport system designed specifically for copper mining operations that completely changed how ore moved from mine to processing areas. This rail system was a technological marvel of its era and became a model for mining transportation across the country.
