Japanese Citizenship and Filipino Recognition

Hi, I was born in Japan. My father is Japanese and my mother is Filipino. I acquired Japanese citizenship. My mother was not able to report my birth in the Philippine embassy there back then.

We went here in the Philippines when I was 1 year old and since then, I was not able to come back to Japan again.

I have been living as an alien here in the Philippines just until this year when I was able to accomplish my Filipino Recognition application in the Bureau of Immigration. Both of my parents are deceased.

I am 23 now.

I am just wondering, because I have been informed that I would have to choose between Japanese and Filipino citizenship as I turn 22.

Am I considered as dual citizen? I do not have Philippine passport and I have no live birth in the Philippine Statistics Authority.

Will I lose my Japanese citizenship? I do not want that because I want to live there after saving enough money. I use my Filipino Recognition for now so that I would not have to pay for living here in the Philippines.

Thank you.

"I have no live birth in the Philippine Statistics Authority."
??? you mean that you have no record even after "recognition" by Philippine government , although you believe you have Philippine nationality.
what kind of "recognition" have you got ?

when does the "recognition" become effective ? i.e. you have got a Philippine nationality from your birth date or from the application (or granted) date ?

I am afraid that you don't understand your situation thoroughly.
it is better for you to consult a lawyer.
