is a town located in Oshima Subprefecture, Hokkaido, Japan. The total area of the town is . As of September 2016, the town had a population of 16,299, and a population density of 44 persons per km2. Mount Komagatake, an active volcano, is located to the east of Mori, and much of the town is part of Ōnuma Quasi-National Park. Mori is the home of ikameshi, a squid and rice dish invented in the mid-20th century. Etymology The name of the town originates from the word "Oniushi", meaning "a forested area" in the Ainu language. In the Japanese language the name of the town is written as , meaning forest. The suffix "", denoting town status in Japan, is pronounced as -chō in every municipality of Hokkaido with the exception of Mori, where it is read as -machi. Geography Mori sits on the eastern coast of the Oshima Peninsula and overlooks Uchiura Bay ( in diameter). The bay, also known as Funka Bay, is rich in squid and is the site of scallop aquaculture, both a mainstay of the town economy. Much of the town of Mori is mountainous or hilly. Hokkaidō Komagatake is an active andesitic stratovolcano on the east of Mori where the town borders the nearby municipalities of Shikabe and Nanae. Major eruptions of Komagatake are recorded as early as 1640, and ash fallout from the volcano is frequent. Mount Gujin (1,113) sits to the west. Volcanic ash from Komagatake covers the town and provides a rich soil for vegetable cultivation. Mori is crossed by several small rivers, including the Torizaki River (), Oshironai River(), Katsura River (), Nigori River (), Shukunobe River (), and the 茂無部川 (). Mori, along with the town of Nanae, shares a coastline on Lake Ōnuma (). Ōnuma, connected to Lake Konuma in Nanae, is technically a shallow pond. Ōnuma and Konuma, which sit at the southern foot of Mount Komagatake, were created when mudflows from an eruption of the mountain dammed the Orito River. Komagatake, as well as Ōnuma and Konuma, are protected as part of Ōnuma Quasi-National Park (), which covers much of eastern Mori. The park is home to alpine plant species such as iwabukuro, a flowering plant of the family Scrophulariaceae, and urajirotade, a flowering plant of the family Polygonaceae. The middle reaches of Komagatake is home to stands of broadleaf trees, including mineyanagi, a species of willow,
