浅川地下壕

The Asakawa Tunnel network spans 10 kilometers beneath Mount Konpira, featuring three main entrances connected through multiple passages and chambers.

The Japanese Army initiated construction in September 1944, employing 500 Korean laborers to create a protected facility for the Nakajima Aircraft Company.

Local preservation groups organize guided tours to educate visitors about the wartime industrial activities and labor conditions in these underground facilities.

Entry to the tunnels requires advance registration through the preservation society, and visitors must bring flashlights, gloves, and rubber boots.

The complex contains seismic monitoring equipment from the University of Tokyo Earthquake Research Institute, accessible during scheduled visits.
