Akayama Underground Tunnels

Last Update : March 31, 2014

 Those underground air-raid shelter tunnels have a total length of 1.6km, and are among the largest surviving air-raid shelters in Japan.
 
 Around the end of the Pacific War, when the American air raids were becoming intense, there is evidence that Tateyama’s Naval air force used these tunnels as air raid shelters. This includes the remains found inside the tunnels of a power generator, accounts from people who actually worked in the tunnels before the war ended, and from verbal statements that there was a hospital facility inside.
 
 These tunnels constitute one of the most historically significant remnants of the Pacific War in the Tateyama area, and they have been officially open to the public since in 2004. Although there is some evidence of construction of the tunnels starting around the late 1930s, the exact date of construction remains unknown due to lack of records.
