Hello everyone! So as the title suggests I (23M) am trying to find my father that is Japanese.As a back story my father met my mother in Japan and they moved back to my mother's home country in Europe where they eventually got married and I was born , after like 3-4 for years he left and we weren't able to contact him in any way. I tried social media but he s on the older side and probably doesn't have any. Do you think hiring a private investigator is worth it or are there any other ways to find him with only his name and some older information about him that dates back more than 20 yrs ago?Thank you
