Former Site of Japanese Military Engineering Facilities in Yinjiatun, Tieling

The former site of Japanese military engineering facilities in Yinjiatun, Tieling, was part of a top-secret military project built by the Japanese army during their long-term occupation of Northeast China. Between 1939 and 1945, they constructed a highly classified military complex—known as the Lanshi Mountain Project—covering an area of approximately 150 square kilometers in the Lanshi Mountain region of Tieling.

Former Site of Japanese Military Engineering Facilities in Yinjiatun, Tieling

To facilitate the long-term occupation of Northeast China, from 1939 to 1945, the Japanese army built a group of top-secret military facilities known as the Lanshi Mountain Project in the Lanshi Mountain area of Tieling, covering a total area of about 150 square kilometers. Existing relics include the concrete building foundation southeast of Yinjiatun, the dedicated railway lines north and south of Lanshi Mountain Railway Station, and the former site of Japanese military industrial facilities in Yinjiatun.

In October 1939, the Japanese army forcibly relocated several villages south of Lanshi Mountain, including Xiadianzi, Badajiao, Jiangdianzi, and Dongdianzi in what is now Yaopu Town, to construct caves, ground warehouses, and dedicated railway lines. In January 1945, over 200,000 laborers were conscripted by the Japanese military. Due to harsh conditions, heavy labor, and widespread disease, nearly 10,000 workers died. There were two crematoria in Yinjiatun, and the original site of the military project became known as the “Lanshi Mountain Ten-Thousand-Corpse Pit.” By August 1945, when Soviet forces entered Tieling and took over, the Lanshi Mountain Project remained unfinished. In March 1946, the project was taken over by the Nationalist army but was left unmanaged before the outbreak of the Liaoshen Campaign, when the Nationalists retreated.
