Château d'Ogawashiro, Japanese castle in Kikugawa, Japan
Ogawashiro castle stands on elevated terrain in Shizuoka Prefecture, featuring traditional wooden architecture with stone foundations and defensive walls that still mark the hillside. The ruins spread across multiple levels of the mountain slope, with remnants of buildings, gates, and watchtowers visible among the vegetation.
During the Sengoku period, Ogawashiro served as a defensive stronghold controlling access routes between the eastern and western regions. The fortress lost its military importance as Japan unified and the era of feudal warfare came to an end.
The layout follows traditional Japanese fortification principles, using the mountain slopes and natural ridges to strengthen its defensive position. Walking through the ruins, you can see how the original builders adapted their design to work with the existing landscape.
Visitors can reach the castle ruins through a marked hiking trail that starts from the base of the mountain near Kikugawa station. The site is open and accessible year-round, though the path is easiest to walk in drier months when the steps are less slippery.
From its elevated position, commanders had clear sightlines to both the coastline and inland territories of Shizuoka Prefecture. This commanding view allowed them to monitor troop movements and ships across vast distances.
