Cupertino Memorial Park - in front of the lantern statue

In 2020, Cupertino-Toyokawa Sister Cities Inc. (CTSC) held the Bell Ringing for Peace even for the first time.  Due to the pandemic, the event was held on Zoom and can be watched here.  The event aims to bring awareness to a 75 years of peace between the US and Japan.

History behind the event: in addition to the  well-known atomic bombings of Hiroshima and Nagasaki during WWII, Toyokawa, Japan was also bombed as it was the location of Japan’s Naval Armory.

On August 6, 2023, CTSC held the fourth annual event to ring bells for Peace, at the Memorial Park, in front of the lantern statue that was gifted to Cupertino from Toyokawa. It was attended by many community members and leaders, including the Cupertino Mayor, Ms. Hung Wei. [Video]
