Annaka Castle, Japanese castle ruins in Annaka, Japan
Annaka Castle is a Japanese castle site in Annaka that sits on a plateau between two rivers, with visible earthen walls and moats remaining from its original construction. The main area now houses a cultural center with restored buildings, including samurai residences and an administrative office that functioned as the district magistrate's headquarters.
The castle was built around 1560 by Annaka Tadamasa but was seized by Takeda Shingen, a powerful regional leader, before being rebuilt in 1614 by Ii Naotoshi. This reconstruction represented a turning point when the site became firmly established under new feudal control and administrative authority.
The reconstructed samurai homes display how residents of the castle arranged their daily lives and the objects they used in those spaces. Walking through these houses, you notice personal items, furnishings, and tools that reveal what living here actually felt like.
The restored buildings are open to visitors, but opening hours can change depending on the season. Wear comfortable shoes for walking around the plateau and plan to spend time both indoors in the buildings and outdoors exploring the grounds.
The castle earned the nickname Fan Castle because of how its buildings are arranged like an open fan, with the main palace in the center and three wings extending outward. This distinctive layout was unusual for its time and makes it easy to understand the strategic thinking behind how the complex was organized.
