The Ansei Treaties of 1858 decided that Hakodate would be opened (allowed foreigners to do business) along with Osaka, Tokyo, Yokohama, Niigata, Kobe, and Nagasaki.
The main site of foreign settlement in Hakodate was Omachi 大町 (present day Nakahama-cho 仲浜町) constructed in 1860, consisting of about 1730 tsubo (approximately 0.6 hectares) in 1878.
The population of the foreign settlement, at its height, was 72: 35 Chinese, 20 British, 6 French, 4 Russians, 3 Americans, 2 Danes and 2 Germans.
