Ichinomiya Castle

Ichinomiya Castle is a mountain fortress in Tokushima with ruins showing stone walls and multiple terraced enclosures that follow the natural terrain. A river flows below the site, which provided additional protection for those occupying it.

The fortress was built in 1338 by the Ogasawara clan, who held the site for generations. Control shifted as regional power changed hands during major conflicts that reshaped the political landscape.

The layout shows how this fortress was designed to display power while protecting those inside. Multiple sections reveal how the space separated different functions and groups of people living here.

The ruins are accessible from outside the main town, with signs marking the way through different sections. Plan to explore on foot and allow time to walk around the different terraced areas.

The stone stairs still visible today date back to the original period and show construction details from that time. Visitors can walk the same paths that were used centuries ago.
