Awaji Island Must-Sees

Awaji Island, the largest island in the Seto Inland Sea, features architectural landmarks like Tadao Ando’s Awaji Yumebutai and the Kiseki No Hoshi Greenhouse. The island preserves historic sites such as the 16th-century Sumoto Castle and the traditional Awaji Ningyo-za puppet theater. Natural highlights include the expansive flower fields of Awaji Hanasajiki and views of the Akashi Kaikyo Bridge, while modern additions include the Nijigen no Mori anime park and the culinary hub of Michi-no-Eki Awaji.
