For twelve generations spanning 387 years, from 1617 to 2004, the Naruse clan maintained one of Japan's oldest surviving castle towers as a private inheritance, making it the only privately owned castle in the country. The tenshu sits on a bluff above the Kiso River in Aichi Prefecture, where the water carves the border between Aichi and Gifu. It is small as Japanese castle towers go, but its complex rooflines shift shape depending on where you stand, revealing different silhouettes from every angle. Only twelve original pre-modern tenshu survive anywhere in Japan, and Inuyama's is one of just five designated a National Treasure -- alongside Himeji, Matsumoto, Hikone, and Matsue.
