On March 21st, there will be a Samurai parade on the island of Miyajima. Japanese and foreigners alike are allowed to wear Samurai armor on this occasion. If you would like to participate, call Hamada-san at the Miyajima Sightseeing Association. Japanese only - it would be rude to even attempt to engage him in English. Cost - 10,000 yen.
