A Baby's Citizenship

The law applies that when a baby is born in the country, the baby will become a citizen in that country. However, applying for a dual citizenship could also make possible with the baby has a Filipino blood.

Well for I could only vouch for our laws. Here as long as one parent is a Filipino the baby will automatically inherit Filipino Citizenship. As for Japan and Sri Lankan laws I cannot say anything about that since they have their own laws in there. But definitely the baby is by default a Filipino Citizen already because of her parent being a Filipino.

I agree with the rest, the child is definitely Japanese. Since she was born in Japanese soil then she should be Japanese. It also applies to foreign embassies.

we actually studied this in constitution class back in college. i forgot the terms since i wasn't paying attention. but as i remember, our prof told us that there are two types of citizenship: (1) by the citizenship of your parents and (2) by the country that you are born in. now, i'm confused as well :) because he explained to us that here in the philippines, we follow the first one. i know for sure that in the USA they follow the second one, which is why a lot of pregnant mothers want to give birth in the states. i hope this helps though. i have a friend who was born in israel with both filipino parents. her birth certificate is even in hebrew, but she's now a dual citizen. maybe, her parent get to choose. man, now i wish i listened more in consti class :)

it is obvious that the citizenship of the baby is a japanese. because she was born in japan.

The baby's citizenship is Japanese by virtue of the circumstances of her birth since she was born in Japan. My niece's case is a bit like that. Both my uncle and aunt were Filipino citizens and they were working in Japan when my niece was born there which automatically makes her a Japanese citizen.

Of course it is obvious Japanese citizen...
