Komoro Castle Remains Kaikoen

Park / Green Space
This park on the site of Komoro Castle in Komoro City, Nagano Prefecture has been selected as one of Japan’s 100 famous castles and 100 famous cherry blossom spots. Komoro Castle is an unusual structure built below the elevation of the castle town, and has also been called Anashiro Castle (“hole castle”). The park is dotted with facilities including the Important Cultural Property San-no-Mon gate, the Toson Memorial Hall, the Koyama Keizo Art Museum, a zoo and a children’s play area. It is appreciated by both tourists and locals looking for a place to refresh and relax. In spring there are 400 cherry blossom trees in bloom, and in autumn it is famous as a great place to see the changing leaves.
