US-Japan Sister Cities by Prefecture

Japan has more sister-community relationships with the United States than any other country, with over 400 sister city and sister state relationships. These linkages connect all but one of Japan's 47 prefectures with 46 US states.

The first US sister-city relationship with a community in Asia was formed between St. Paul, Minnesota and Nagasaki, Japan, on December 7, 1955, based on a desire for peace and a celebration of historical ties.
