For the full Miyajima experience, why not walk the streets and visit the shrine dressed in a traditional Japanese kimono? There are a number of shops on the island offering kimono and yukata (a summer kimono) rentals. It's easy to do - just go and choose your favorite design and the shop staff will help you get dressed. Then you're free to wander the island in full Japanese garb.
