Seal of Hercules Sister City TsushimaHistory of the Sister City Relationship
On November 5, 1981, officials from Tsushima, Japan came to Hercules to sign an affiliation document that formalized the relationship between the City of Hercules and the City of Tsushima. The ceremony took place in Refugio Valley Park and included the dedication of the Tsushima Friendship Bridge that spans the creek leading to the lake. Tsushima re-named a street previously known as Nishiki-machi to Hercules Street. Hercules also has a street named for our Sister City, Tsushima Avenue, which extends from San Pablo Avenue west to John Muir Parkway.

The Hercules Sister City Association
Every other year, Hercules recruits, selects, and prepares Hercules Youth Ambassadors (middle and/or high school students) to represent Hercules on a visit to Tsushima and other parts of Japan. Many opportunities are sought to raise the funds necessary to defray the students’ cost of the trip. Interested students can be sent an application packet by sending an email to

In addition to Hercules' trip to Tsushima, Tsushima also sends a delegation to Hercules on an bi-annual basis. The group is called the Tsushima Friendship Delegation and consists of eight to twelve students and adults. Frequently, past Youth Ambassadors and their families serve as hosts for Delegation members. Additional host families are also sought from existing HSCA members and others who have indicated a desire to provide a home stay experience for the visitors from Tsushima. A successful hosting experience includes a commitment to be with the hosted individual the entire time they are in Hercules (3-4 days). Some of that time will usually involve City of Hercules-sponsored meals and activities.
