Miura Peninsula (三浦半島 Miura-hantō) is a peninsula located in Kanagawa, about an hour on the train south of Tokyo. The peninsula is a popular day trip from Tokyo, although ideally you’ll need a car to get around. The United States naval base is located in Yokosuka on the eastern side.
Things to Do

A public park that contains a small museum showcasing the extensive marine in the Hayama bay area and includes artifacts collected by the Emperor Shōwa (Hirohito) who spent much time at the Hayama Imperial Villa during his reign.

A small shrine in the town of Hayama. It was built by the first Kamakura shogun, Minamoto no Yoritomo in the 12th century, and today is famous for the red torii gate which stands in the middle of the sea on a small island of rocks. From the shrine’s ground you can see Enoshima and, on a clear day, Mount Fuji.
