Start Your Iwaya Sightseeing by Viewing the Small Island of Creation Mythology

About this spot

A small island floating just offshore from Iwaya Port, said to be connected to Japan's creation mythology found in the Nihon Shoki (日本書紀) and Kojiki (古事記). It is Iwaya's symbol, distinguished by its unusual layered rock formations called "Senjojiki" (千畳敷) with striking striped patterns. The clear morning light creates a striking contrast with the sea's color. Located within walking distance from the port town, it's easy to view leisurely from the promenade on the opposite shore. The Akashi Kaikyo Bridge (明石海峡大橋) is also visible in the distance, setting the perfect mood for the day's coastal journey ahead.

Tips

A short walk from Iwaya Port. Landing on the island is not possible, so the basic approach is to view it from the waterside promenade and observation spots. Summer mornings have strong sunlight, so bring a hat and stay hydrated.

Best time to visit

Approximately 40 minutes required. Best viewed in the soft morning light.
