In the final phase of World War II, to defend against a U.S. attack on Taiwan, Japan deployed five divisions and seven brigades on the island; the key northern unit was the 66th Division stationed in Taipei, commanded by Lieutenant General Nakajima Kisaburō. Its code name was “Kan”—hence, locals in Taishan District still call it the “Kan Force.” The “Kan Force Bunker Ruins” lie at the end of Lane 352, Section 1, Mingzhi Road, within Tongrong Village, halfway up a secluded hill with excellent sight-lines. Serving then as the Japanese combat headquarters—operations and command center—the bunker has two levels; stairs on the ground floor descend to a basement divided into rooms 2–4 m wide and 3.65–4.5 m deep, fitted with bathrooms and offices; capacity is estimated at 30–40 troops. In front of the bunker once stood the 0.7-hectare Tongrong Children’s Park, a Tudigong temple and a pavilion. To preserve the original appearance and history of the Japanese military deployment in northern Taiwan, the district office has expanded the educational and recreational functions of the bunker and park, integrating images of major local attractions to create a cultural and historical image park that serves as a local teaching site.
