Where should I go for sightseeing in Okayama?

Okayama is roughly divided into three areas: Bizen, Bitchu, and Mimasaka. Okayama Korakuen and Kurashiki Bikan Historical Quarter are popular spots, but there are many other places to visit. Enjoy the diverse Okayama, from the mountains to the sea, from Ushimado, where you can see the beautiful ocean known as the "Aegean Sea of Japan," to the huge limestone cavern Ikura Cave, which was formed over a long period of time.
