The Doto Expressway connects the central region of Hokkaido with eastern regions of the northern island. Starting to the south of Sapporo and the north of Shin-Chitose Airport, the expressway heads east to Honbetsu JCT where it splits into two.
The name of the expressway comes from the words 'Hokkaido' （北海道） and 'East' （東）. The Doto Expressway is one of the least used expressways in the whole of Japan.
There is a speed limit of just 70km/h on this expressway.
