In 1973, Torrance established a sister-city relationship with Kashiwa, Chiba, Japan, as part of the Sister Cities International program. Since then, citizens of Torrance have regularly engaged in cultural exchange with Kashiwa through the guidance of the Torrance Sister City Association, which facilitates a Japanese cultural festival, a yearly student exchange program, and contact between officials of the two cities. North High is the official sister high school of Kashiwa Municipal High.
