Kameda Peninsula

The Oshima Peninsula in southwest Hokkaido is divided into east and west in the south, and Matsumae refers to the eastern part of the peninsula. The western part is called the Matsumae Peninsula. It occupies the eastern part of the Hakodate lowlands, which connects the town of Morimachi with Hakodate Port from north to south, and faces Uchiura Bay to the north, the Pacific Ocean to the east, and the Tsugaru Strait to the south. It is an extension of the Tohoku region, and volcanic rocks make up the majority of the area, with volcanoes such as Komagatake, Yokotsudake, Esan, and Hakodateyama erupting through the Neogene layers. All of the rivers that carve the mountains are short, and as the mountains approach the sea, there is little flat land, confined to the coast and river basins. Fishing is the main industry, but in recent years it has become an area for migrant workers.

北海道南西部の渡島半島(おしまはんとう)は南部で東西に分かれるが、その東の部分をいう。西の部分は松前半島という。森町市街地と函館(はこだて)港を南北につなぐ函館低地帯の東部を占め、北は内浦湾、東は太平洋、南は津軽海峡に臨む。東北地方の延長部にあたり、新第三紀層を切って駒ヶ岳(こまがたけ)、横津岳、恵山(えさん)、函館山などの火山を噴出し、火山岩類が大部分を占める。山地を刻む河川はどれも短く、山地が海に迫るため平地は少なく、海岸、河川流域に限られる。漁業を主とするが、近年は出稼ぎ地帯となっている。
