Fort Hakodate Ruins

Fort Hakodate Ruins are the remains of a military fortification on Mount Hakodate with artillery batteries, observation posts, ammunition depots, and communication facilities. Bunkers and underground passages are accessible via walking trails and offer insight into the defensive installation's military infrastructure.

The fortress was built starting in 1898 to protect Tsugaru Strait from Russian naval forces. Additional reinforcements continued until 1940 as tensions with neighboring powers grew.

The site displays Japanese military engineering from the Meiji period, where traditional stone masonry techniques blend with modern defensive structures. Visitors can still see the traces of these construction methods in the preserved walls and underground passages.

The site connects well with Hakodate's ropeway system, making access to the mountain straightforward. Most bunkers and passages are walkable year-round, though sturdy shoes and a flashlight are recommended.

Concrete markers from 1899 still stand at three locations on Mount Hakodate, marking the original boundaries of the military zone. These markers serve as silent reminders of the installation's original extent and security perimeter.
