Onoji Castle

Onoji Castle is a Japanese fortification in Kanagawa Prefecture that uses stone walls, wooden buildings, and defensive moats adapted to the mountainous landscape. The structures blend naturally with the hillside terrain.

The castle developed during the Sengoku period when regional lords built fortified positions to protect against rival clans. This era saw the rapid spread of such fortifications across Japan.

The castle displays traditional Japanese building methods that reflect how feudal societies were organized and defended. You can see these design choices in how the structures are arranged across the hillside.

You can reach the castle grounds via marked trails and find information panels at key locations. Wearing proper footwear is helpful for walking on the sloped terrain.

The stone foundations demonstrate specialized construction methods that allowed this fortification to withstand attacks. These techniques differ notably from European castle building and showcase Japanese engineering skill.
