Oshima Peninsula

Bordering the world's largest ocean, Oshima Peninsula is located west of the Pacific Ocean in northern JAPAN. More specifically, Oshima Peninsula is the southwestern extension of Hokkaidō, Japan's second-largest island after Honshū (south of Hokkaidō). Two smaller peninsulas - Matumae Peninsula to the southwest and Kameda Peninsula to the southeast - are part of Oshima; together, these peninsulas form an upside-down Y shape jutting southward from Hokkaidō. Oshima Peninsula is surrounded by water on its west, east, and south coastlines. Sea of Japan is west of Oshima, the Uchiura Bay in the Pacific Ocean is east, and Tsugaru Strait is south. Connecting the Sea of Japan and the Pacific Ocean, Tsugaru Strait separates Hokkaidō and Honshū islands. Small islands such as Okushiri-tō and Ō-shima are found in the Sea of Japan, west of the peninsula. Esachi, Kaniisco, Matsumae, Minamikayabe, Mori, Nanae, and Shikabe are some communities on Oshima Peninsula. A word you may recognize from a notorious event several years ago - Fukushima - is a town on the peninsula southern coast. This town is not the location of 2011's Japanese nuclear disaster. Instead, the town of Ōkuma in Fukushima Prefecture on Honshū island is where an earthquake and tsunami led to explosions and meltdowns at the Fukushima Daiichi Nuclear Power Plant.
