If only the towering walls of Sasayama Castle could talk! But as they can't, inquire if tours are available to hear a couple of its tales instead.
You'll have sightseeing choices galore when spending time in Sasayama. Sasayama Castle is a good place to start here, but there are lots of other interesting attractions to experience. Eitakuji Temple, Anma Family Museum, and Kasuga Shrine are near the fortified complex and will top off your day nicely.
