Sapporo (Dy, "important river flowing through a plain" in Ainu language) is the capital of Hokkaido and Japan's fifth largest city. Sapporo is also one of the nation's youngest major cities. In 1857, the city's population stood at just seven people.
In the beginning of the Meiji Period, when the development of Hokkaido was started on a large scale, Sapporo was chosen as the island's administrative center and enlarged according to the advice of foreign specialists. Consequently, Sapporo was built based on a North American style rectangular street system.
