About Us | Broomfield SCO

The Sister City movement in the United States was inaugurated by President Eisenhower in 1956 as the "People to People program," whose purpose was to establish greater friendship and understanding between the people of the United States and the peoples of other nations through direct contact.

Ueda, Japan

Broomfield was introduced to Maruko, Japan, and encouraged to establish a sister city relationship by Up With People (UWP) when they were headquartered in Broomfield. The mayors of Broomfield and Maruko, Japan signed the first "Friendship
City" document in May 2001. Maruko became the first sister city for Broomfield. In 2005, Maruko and other smaller municipalities merged to become part of the larger community of Ueda in Nagano prefecture. Broomfield's and Ueda's mayors signed an updated “Friendship City” agreement in 2006.

Cheyenne and Arapaho Tribes (OK)

Our relationship began in 2019, sparked by a simple lunch with two Arapaho elders and their grandchildren. Since then, it has grown to include visiting delegations, a soil exchange ceremony, basketball exhibitions, support for language and cultural camps, and more.

This partnership was formally recognized with an official Sister Cities signing ceremony in March 2025—making Broomfield only the second U.S. community to form a Sister Cities partnership with a sovereign Native nation.

Lalitpur, Nepal

Established in September 2025 in Broomfield through a formal signing ceremony, our Sister Cities relationship with Lalitpur shines a spotlight on its vibrant traditions in art and craftsmanship, while creating opportunities for education, tourism, and shared community enrichment.
