A national natural treasure, “White Arums,” bloom in Memanbetsu-kohan. During winter, plants in the Lake Abashiri-ko Memanbetsu-kohan area endure the weight of thick snow from underneath. As the snow melts, the plants arise from sleep. Memanbetsu-kohan is located in Abashiri Quasi-National Park; in the park, there is a natural national treasure “Memanbetsu hygrophyte community” spreading over the area of 56 ha in the broad-leaved deciduous forest of Fraxinus mandshurica and Alnus japonica. Especially “white arum (Mizubasho)” is distinctive, and its community is based at the lakefront. The community of white arums covers one of the nation’s largest areas, and blooming of the flowers tells us the coming of spring. The best season for viewing is from late April to early May every year.
