Northern and Central Californian Sister Cities in Japan

California and Japan share a long history of mutual exchange and cooperation, not only at economic and diplomatic levels, but also at the person-to-person level.

According to statistics issued by the Council of Local Authorities for International Relations (CLAIR), as of May 1, 2018 there are 451 sister-city relationships between Japan and the U.S., and Japan has more sister city relationships with the U.S. than with any other country. Of these, there are 105 sister city relationships between California and Japan as well as a sister state relationship between the State of California and Osaka Prefecture, making California the U.S. state with the largest number of Japanese sister cities. Among the Japan-California relationships, 65 are within this Consulate's jurisdiction.

The interactions through sister-city relationships include mutual visits to the cities by mayors and citizens, anniversary events, student exchange, and economic exchanges.

The Consulate General of Japan in San Francisco actively supports activities resulting from these sister-city relationships, based on the idea that the promotion of region-to-region relationships through sister-city interactions further strengthens relations between Japan and the U.S.
