The Japanese Invaders' Hushan Military Fortress

　　The Japanese Invaders' Hushan Underground Military Fortress was one of the 17 secret fortification projects constructed along the Sino-Soviet and Sino-Mongolian borders between 1934 and 1939 by the Kwantung Army of Japan, using tens of thousands of Chinese laborers.

　　The fortress is located in the mountains northwest of Hushan Town, Hulin City. It consists of seven mountain ranges: Menghushan (including East Menghushan, Central Menghushan, and West Menghushan), Hubeishan, Hudongshan, Hexishan, and Hu Xiaoshan. The front stretches over 10 kilometers, extending 40–45 kilometers in depth, with the central area alone covering more than 100 square kilometers. The entire fortress was built with reinforced concrete, featuring an enormous scale, complex structure, and complete facilities. Each underground position included rest areas, command posts, ammunition depots, storage rooms, power stations, medical wards, kitchens, and toilets. The Japanese army boasted that it was the “Maginot Line of the East.”

　　Lessons from the past serve as a guide for the future. To remember this painful history and preserve evidence of Japanese invasion crimes, the state and provincial/municipal governments invested over 6 million yuan to excavate and clear the main section of the Hushan Underground Military Fortress — the Menghushan segment’s underground vaults. A total of 3,800 meters of underground tunnels have been cleared, with more than 1,200 meters restored and reinforced. On top of the ruins, the “Japanese Invaders' Hushan Underground Fortress Site Museum” has been built. This thematic museum features unique design, exquisite construction, clever layout, and displays a large number of unearthed artifacts and historical relics.

　　The Japanese Invaders' Hushan Underground Military Fortress site and museum have been listed as a provincial-level key cultural relics protection unit, a provincial-level patriotic education base, and a national-level cultural relics protection unit. It is a tourist attraction of global significance.
