[edit] Kurile fortresses

This defensive structure in the Kurile Islands was somewhat similar to the Karafuto fortifications. The key Japanese position was on Shumushu Island, whose defense consisted of permanent emplacements protected by field and AA artillery. A garrison of over 8,000 men reinforced by sixty tanks defended the islands of Shumushu and Paramushiro. All the coastal sections convenient for landings were covered with permanent emplacements and bunkers interconnected with underground passages and trenches. All the warehouses, power stations and hospitals were underground up to 50 m deep.

The other fortifications stay ubiqued in Paramushiro island, also exist some similar military building in others North Kuriles (Shimushiro, Onnekotan, Uruppu, Matsuwa, etc.) and Etorofu, Kunasiri, Shikotan and Habomai archipelago, in Southern Kuriles.
