Nagahama Castle, Castle ruin from Sengoku period in Numazu, Japan
Nagahama Castle is a Sengoku-period castle ruin set on a hill above Suruga Bay in Numazu, Japan. Stone walls and layered defensive platforms remain on the site and can still be seen today.
The Late Hojo clan built this fortification in the 1570s during territorial conflicts with the Takeda clan. It was one of several strongholds raised during that period of frequent fighting between regional powers.
The path up the hill winds through what were once several gate positions, following a layout designed to slow any attacker down step by step. Walking it today gives a clear sense of how defenders thought about controlling movement through the site.
The paths on the hill are steep and uneven in places, so sturdy shoes make the walk much easier. Visiting during daylight is the best way to navigate the slope safely and take in the views from the top.
The hilltop served as a naval observation point over Uchiura anchorage, not just a land fortress. This combination of land defense and sea surveillance in one site was relatively rare among the strongholds of the region.
