We regularly receive emails from Japanese-Filipinos searching for their Japanese fathers. Many of these adults were abandoned as children, along with their Filipino mothers, while others were forced to leave Japan for various reasons.

The Citizens' Network for Japanese-Filipino Children primarily offers support to abandoned Japanese-Filipino children (JFC). Their services include locating fathers within Japan and providing legal assistance, in cooperation with the JFC Lawyers Association, with issues such as paternal financial support and acquisition of Japanese nationality.
