History
The area of Wassamu was inhabited by Ainu people and the name comes from the Ainu word "wat-sam", which means "next to the elm tree". Wassamu was incorporated as a village 1915 after separating from Kunbuchi. It was raised to town status in 1952.
Government
Wassamu has a mayor-council form of government with a directly elected mayor and a unicameral town council of eight members. Wassamu, collectively with the other municipalities of Kawakami sub-prefecture, contributes three members to the Hokkaidō Prefectural Assembly. In terms of national politics, the town is part of the Hokkaidō 6th district of the lower house of the Diet of Japan.
Economy
The economy of Wassamu is overwhelmingly agricultural. Before World War II, Wassamu was located north of the northern limit of rice cultivation, so pyrethrum was the main crop. After the war, when pyrethrum production moved to China, the fields in the mountains fell into disuse, but as the northern limit of rice cultivation moved northward due to improved varieties, rice suitable for cold climates began to be planted, and the chrysanthemum fields in the flatlands were transformed into farmland. Today, in addition to the largest pumpkin cultivation area in Japan, the village is known for producing "winter cabbage," which is preserved under the snow and shipped in winter.
Education
Wassamu has one public elementary school and one public junior high school operated by the town government, and one private high school.
