colorado-japan sister cities

Colorado is fortunate to have many sister relationships with Japan, including sister cities, a sister state, and a historic sister byways relationship!

See below for details.


Sister City Exchanges are unique, life-changing trips that foster global friendship and understanding. They connect people from two different cities, typically in different countries, to share culture, history, and ideas. You don't just visit—you immerse yourself, building lasting bonds that bridge communities and continents!


Some of these programs do not have an online presence, as they are nearly completely volunteer-run. If you have problems finding a contact for any of the below listed programs, please contact us at info@jascolorado.org and we will do our best to connect you.
