Aso Shrine (阿蘇神社 Aso-jinja?) is a Shinto Shrine in Aso, Kumamoto Prefecture, Japan. Aso is one of the oldest shrines in Japan. This shrine holds several Important Cultural Properties, including Ichi-no-shinden (一の神殿), Ni-no-shinden (二の神殿), and Rōmon (楼門).
The Aso Shrine was heavily damaged in the 2016 Kumamoto earthquakes. The shrine's rōmon (tower gate) completely collapsed. The haiden (worshiping hall) also collapsed.
Aso Shrine at Mount Aso in Kyushu is traditionally held to have been a center of worship before the accession of Emperor Jinmu. The shikinaisha shrine complex at Ichinomiya in what is today Kumamoto prefecture was said to have been established in 281.
Records link the founding of the shrine to the reign of Emperor Keikō. By the middle of the 11th century, the shrine was involved in national issues as they played out across Kyushu. During the ascendancy of the Kamakura shogunate, the Hōjō clan exercised a significant influence over the affairs of Aso Shrine.
The shrine is dedicated to the veneration of Takeiwatatsu-no-Mikoto (健磐龍命), who was a grandson of Japan's first emperor and the brother of Emperor Suizei, the second monarch on the traditional list of emperors. In the same period that Emperor Jimmu was establishing his palace at Kashihara at the foot of Mount Unebi in Yamato province, Tateiwatasu was sent to Aso where he helped establish a number of agricultural communities; and later, he is said to have built a palace at Miyagi.
