I already did some research but I couldn't find any info on people with the same situation as me and successfully did this. It's a very specific situation so please bear with me.
First of all, I was born in Japan, have lived there until I was 7 and moved to the Philippines without ever going back to Japan. My father is Japanese and my mom is Filipino. For some reasons, my father never put me and my siblings in his koseki and my mother just tells me she doesn't know either. My parents were never married. As I know, even if they are not married, my father has the duty to put us in his koseki, but I assume he did not want to cuz I heard he has another family and even stopped contacting us when I was like 17. So I'm a Philippine passport holder now.
My mother tried to go to the Japanese embassy in the Philippines when my siblings were still minors but was told there's nothing we can do unless we have a contact to our father
Me and my siblings are all over 21 years old now so I'm aware we cannot acquire citizenship anymore through my father's koseki. However I found out there's a Nikkei visa.
Is it possible to apply even without my father's documents? I don't think I can get any from him since I cannot contact him… I don't even know where he is now or whether he's alive or not. I only have birth certificate, old copy of my father's passport, and some DNA documents. I also have some photos with my father too.
Also, I am now married to a Korean national and living in Korea (I'm not a permanent resident yet). If I can get a Nikkei visa, is it possible to bring my husband to Japan?
I recently went on a trip to Japan and visited the neighborhood where I have lived and realized more that I wanna live there again… Am I hopeless unless I get in touch with my father? If he has passed away, is there any other way to prove my father is a Japanese national?
