Yes, there are several organizations and groups that help Filipino people find their Japanese birth fathers.
One of the most active and well-known organizations is the Philippine Nikkei Jin Kai International (PNJKI). This non-profit organization seeks to preserve and promote Filipino-Japanese relations and culture. They also assist Filipino children of Japanese fathers in search of their biological dads.
Another organization is KBF (Kaibigan ng mga Batang may mga Ama sa Japan / Friends of Filipino Children in Japan). KBF is a group that helps Filipino children born out of intermarriages between Filipinos and Japanese.
In addition to these organizations, there are several online communities and support groups that connect Filipino children with their Japanese fathers. One such group is the "Filipino-Japanese Children Network", which is a forum where children can share their stories and connect with others who may have similar experiences.
It is important to note that finding Japanese birth parents can be a difficult and emotional process. These organizations and groups provide emotional and logistical support, but it is important to manage expectations and be prepared for any outcome.
