Dipnaysupuan Japanese tunnel is an interconnected network of tunnels in Tukon Hills, Basco, Batanes, the Philippines. It served as a shelter for the Japanese imperial forces during the Japanese occupation in the Philippines until the end of World War II.
Because of its strategic location, the Japanese imperial forces forced the Ivatans to dug tunnels in Tukon Hills for their shelter. The Japanese soldiers spent years hiding in these tunnels until the end of Word War II.
