About CTSC
The Cupertino Toyokawa Sister Cities (CTSC) organization promotes cultural awareness and friendship between the cities of Cupertino and Toyokawa, Japan. The relationship began in 1978 and in 2023, commemorated its 45th anniversary through a Virtual Ceremony.
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 (CCBF) held every year on the last weekend in April.
If you have any questions or comments, or would like to join our committee and volunteer, please contact the Cupertino-Toyokawa Sister Cities organization.
