The Miura Peninsula (三浦半島 Miura-hantō) is a peninsula located in Kanagawa, Japan. It lies south of Yokohama and Tokyo and divides Tokyo Bay, to the east, from Sagami Bay, to the west. Cities and towns on the Miura Peninsula include Yokosuka, Miura, Hayama, Zushi, and Kamakura.
The peninsula is a bed town to those who work in Tokyo and is also popular tourist destination for people from Tokyo. It is also an important area of Japan's self defense, with the National Defense Academy of Japan on the western side of the peninsula and the Yokosuka Naval Base on the eastern side, for both Japanese Maritime Self Defence Force and United States Seventh Fleet.
A significant portion of Tokyo's electricity is generated at Tokyo Electric's power station at Uraga, and important R&D activities on the next-generation mobile phones are done at Yokosuka Research Park.
There are three important lighthouses on Miura Peninsula. Kannonzaki Lighthouse stands at the easternmost tip of the peninsula, facing Cape Futtsu across the bay. At Cape Tsurugi on the eastern side of the southernmost tip of the peninsula is the Tsurugisaki Lighthouse, one of Japan's oldest western style lighthouses, first illuminated in 1871. On the island of Jōgashima, off the southernmost and western tip of the peninsula, stands the Jōgashima Lighthouse.
