Geography
Mori sits on the eastern coast of the Oshima Peninsula and overlooks Uchiura Bay. The bay, also known as Funka Bay, is rich in squid and is the site of scallopaquaculture, both a mainstay of the town economy. Much of the town of Mori is mountainous or hilly. Hokkaidō Komagatake is an active andesiticstratovolcano 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 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, doronoki, a Populus species, birches, and mizunara, a species of oak. Ōnuma is home to watershields, carp, and wakasagi, a species of smelt used in Japanese cuisine.

History
Mori was settled early in Japanese history as evidenced by the Jōmon-periodarchaeological sites now designated as the Washinoki Site. The town was settled by the Japanese in the 15th century. The settlement, like many other coastal areas of Hokkaido, was established as a Pacific herring fishing base. Fishermen operating out of Hakodate noted the richness of herring in the Mori area, and soon established a base in Mori. The base became the village of Washinoki, and was administered as part of Hakodate. Kōbō Abe, a samurai and naval commander of the Tokugawa shogunate, lost the capitol at Edo to forces loyal to the Meiji Emperor as 1868 as part of the Boshin War. Enomoto fled from Edo and landed his fleet of eight steam warships, the remainder of the Tokugawa Navy, a Washinoki en route to establishing a base at Hakodate. The present-day town of Mori became part of Enomoto's Republic of Ezo. Enomoto and the republic were soon defeated in the Naval Battle of Hakodate, and all of Hokkaido, including the villages of Mori, came under the rule of the central Japanese government. Mori was incorporated as a town in 1921. A great fire broke out in the town in 1961 and half of Mori was burned, with 554 homes destroyed. The town of Sawara was merged into Mori on April 1, 2005.
Economy
The fishing industry of Mori focuses on the aquaculture of scallops. The volcanic ash from Mount Komagatake has created a rich soil for fruit and vegetable production in Mori. The town is noted for its production of melons, tomatoes, pumpkins and prunes. Sawara is noted for its production of blueberries and at the town's Michi No Eki, you can sample blueberry jam and ice cream.

The Sawara Branch Line, which runs between Mori Station and Ōnuma Station in Nanae, serves several small stations in the Sawara area.
