The Antioch/Chichibu Sister City organization is a volunteer, non-profit organization comprised of interested citizens in both cities.

The purpose of the organization is to give citizens of Antioch and Chichibu the opportunity to experience each other's country and culture. The benefits of our program include the making of many friends between the two cities.

Our organization is unusual among other sister-city organizations because the visits between the two cities are "home-stay"; that is, visiting delegates stay in the homes of host families. We believe this allows the delegates to experience life in the visited country more directly than when staying in hotels. In addition, delegations include both students and adults. Usually the delegations are between 10 and 12 in number, varying according to the availability of host families and the interest in the visiting city.
