Omishima Island — Samurai Armor and Art Museums

Omishima is the largest island on the Shimanami Kaido cycling route, home to Oyamazumi Shrine which houses Japan's most extensive collection of samurai armor and swords — over 80% of designated National Treasure arms and armor in Japan are stored here. The shrine's history dates to 594 CE, and for centuries warriors dedicated their armor to the shrine before battle, creating an unparalleled collection.

The island also features the Toyo Ito Museum of Architecture, a minimalist white structure designed by Pritzker Prize winner Toyo Ito, creating a unique juxtaposition of ancient and contemporary culture.
