Founded traditionally in 281 BC, Aso Shrine is one of the oldest shrines in Japan. Ancient Chinese chronicles from the 7th century record that the people of Aso held festivals every time Mount Aso erupted to calm its wrath. The shrine's six main buildings — including the iconic Romon gate — are designated Important Cultural Properties of Japan, rebuilt in the Edo period by the Kumamoto domain.
