Historically, Awaji was also known as Miketsukuni (“Land of Food”), supplying high-quality ingredients to the Imperial Court, a legacy that continues to shape the island’s reputation today.
Awaji Island History and Mythology

Birthplace of Japan According to Mythology
According to Japan’s oldest chronicles, the Kojiki and the Nihon Shoki, Awaji Island was the first island created by the deities Izanagi and Izanami during the creation of Japan.

One of the most important places connected to this legend is Izanagi Shrine, dedicated to Izanagi and traditionally regarded to be Japan’s oldest shrine. It remains a popular destination for visitors interested in Japanese mythology, history, and spiritual traditions.
