Edwin Dun, an Oyatoi gaikokujin, began development of Makomanai in the 1870s with a pioneer stock farm. The valley of Tokiwa remained undeveloped for a long time. Flood control projects were begun in the later half of 20th century; straightening the river course in the 1960s. Now a residential zone exists along the northern half of Tokiwa along National Route 453. Houses cover the surrounding hilltops around Makomanai. At the confluence with the Toyohira River is Makomanai Park. Cherry salmon migrate to and spawn in the park every year.
