Building bridges for peace
Who We are
Who We Are
In 1853, Commodore Matthew Perry sailed his black ship into Uraga harbor (near Yokohama) and a treaty of peace and amity was signed one year later. This relationship has grown into one of the closest political, cultural, and economic relationship of our time. We continue to celebrate our ties to genuine friendship and shared values and promote the Sister City goals of world peace through better understanding.
The San Diego-Yokohama Sister City Society was established in 1957 as one of the first sister cities on the west coast. The Society has sponsored numerous exchanges in the field of arts, business, culture, and education between the City of San Diego and the City of Yokohama, Japan.

Our legacy is helping the children who are our next generation to work with each other to create peace.
