Sasaune Gallery, Underground copper mine entrance in Takahashi, Japan.
Sasaune Gallery is a network of tunnels carved deep into a mountain, serving as the entrance to a former copper mining area. The passages reveal an intricate system of shafts and chambers dug by hand over many generations.
The site originated in the 17th century and operated for over 300 years until closing in 1972. It supplied copper during Japan's rapid industrial development and modernization period.
The gallery reflects generations of workers who shaped this mountain and remain part of the region's identity today. Visitors can observe in the passages how people labored here and passed down their knowledge and skills.
The passages are best explored with a guide, as the tunnels are narrow and lighting is limited throughout. Sturdy shoes and a jacket are recommended since the underground air is cool and surfaces can be slippery.
Mining tools and equipment remain at their original workstations in the lower chambers, frozen in time. These details allow visitors to follow the actual day-to-day labor of miners step by step.
