Built in 1240, Bicchu Matsuyama Castle is both an Important Cultural Property of Japan and is counted among Japan’s top 100 castles. The castle is located atop a mountain at an altitude of 430 m, making it the highest fortress with an existing castle tower in Japan. Visitors to the castle are treated to a spectacular sight, especially in the early mornings of fall and winter when the clouds spread out to form a “sea of clouds” around the castle. Also in fall, when the trees change color, the landscape becomes painted in a deep vermilion as if the castle walls were aflame, offering visitors a truly majestic sight.
