In this age of decentralization, Chiryu City intends to develop cultural exchanges with associates in other parts of the world who can become good partners.
The city concluded a friendship city agreement with Ina City in Nagano Prefecture in November 1994, and a sister city agreement with the City of Wyndham, Australia, in February 2000.
Furthermore, at the Expo 2005 Aichi, Japan “Love the Earth Expo,” the Republic of Iceland became a partner as a friendship country of Chiryu City.
