Sister Cities Since 1978
The Cupertino Toyokawa Sister Cities (CTSC) organization promotes cultural awareness and friendship between the cities of Cupertino and Toyokawa, Japan. The relationship celebrates its 44th anniversary in 2022.
The friendship is built through the annual student exchange program, and also the quinquennial (every five years) adult exchange program.
The cultural awareness is promoted through the annual Cupertino Cherry Blossom Festival (CBF) held every year on the last weekend in April.
