Boli Secret Airbase

Boli Secret Airbase is yet another Japanese military airbase discovered in China's northeast, following the Dongning Fortress and the Hushitou Fortress. It is located in the dense forests about three kilometers northwest of Boli County’s urban area, covering an area of 47.4 square kilometers, and was built around 1940.

Boli Secret Airbase was an important Japanese aviation ammunition depot during the invasion of China, supplying the Japanese forces in the northeast and north China battlefields with aviation equipment and munitions. Together with five other nearby military airfields — Huzhu, Rongguang, Jixing, Shuanghe, and Boli East Mountain — it formed the second line of defense in the so-called "Eastern Maginot Line." This network served as a crucial military base that secretly supplied arms and aerial support to permanently occupy the northeast and reinforce the first line of military fortifications.

The airbase features 14 cave storage facilities, each approximately 80 meters long and about 8 meters wide, equipped with wiring, drainage systems, and ventilation. Surrounding these cave storages are rows of cement bungalows known as "field depots," which offer high concealment. The site also includes a maze of winding roads (commonly called “confusing paths”). A perimeter electric fence surrounds the base, with an additional layer of barbed wire both inside and outside the fence. Watchtowers and searchlights are positioned all around, while the surrounding mountains remain in their original wild state, with shell craters, unexploded shells, shell fragments, and bullets scattered throughout.

As a historical witness, Boli Secret Airbase silently tells the world that Japanese invaders intended to turn Boli into a rear base for their expansion. Any denial or attempt to whitewash their aggression is futile. Serving as a vivid teaching tool for patriotic education, the airbase allows visitors to recall this humiliating chapter of history and stirs up a sense of national pride.
