Ikuchi Island: The “Island of Gods” in Onomichi, Home to Kosanji Temple and Other Must-Visit Attractions

Ikuchi Island is one of the Geiyo Islands floating in the Seto Inland Sea. It serves as a key stop along the Shimanami Kaido and is often referred to as the "Island of Gods." This name originates from historical records stating that before Itsukushima Shrine was established on Miyajima, a temporary shrine was built on Ikuchi Island. Even today, Itsukushima Shrine can be found in Setoda Town on the island.

Additionally, Ikuchi Island is the birthplace of the renowned Japanese painter Ikuo Hirayama, who was honored as a distinguished citizen of Hiroshima Prefecture. A museum dedicated to his works has become a popular tourist attraction.

In this guide, we’ll introduce four must-visit spots on Ikuchi Island that showcase its cultural and historical significance.
