The Sadamisaki Peninsula is the westernmost part of the island of Shikoku, and is the narrowest peninsula in Japan. It is covered by the town of Ikata, Ehime Prefecture, and is home to the Ikata Nuclear Power Plant. The peninsula is bounded to the north by the Inland Sea, to the south by the Uwa Sea (Pacific Ocean), and to the west by the H yo Strait, which separates Shikoku from Ky sh . This combination of mountains and ocean make the Sadamisaki Peninsula a popular sightseeing destination, especially in the spring when the sakura are in bloom.
