Thank you for your helpful advice. I have questions for you when you register your kid, does your baby get dual nationality up to 21 years old? and he/she needs to choose one after that right? I'm going to JP in January so its advisable to make JP or MY passport for the baby? I've been googling around but not much info could be found about this
You get a Malaysian birth certificate when she delivers. Your wife then goes to the Japanese embassy to get a Japanese birth certificate and passport made.
The next part is important: she then has to add the kids to her family register. This is called a koseki-tohon and your wife has to do this at the city hall (in Japan) where her koseki is currently maintained. In Japan, all birth matters are at the local level - the city level (ku). I'm not sure if your wife split herself from her family's koseki after marriage but now would be a good time to do so i.e. she is starting a new family record. Previously, let's say her family name's Tanabe, she would be recorded as a daughter under her father's koseki - "Tanabe". When females marry, they (usually) leave their family's register and enter their husband's register.
Since you are not a Japanese citizen, she would then start a new koseki with her as head of family. You cannot be on a koseki. You would be just an unofficial afternote at the bottom of the koseki. Your kids would then usually take her last name in Japan and be official dependents in her koseki. You have to be prepared for the fact that they might have 2 official names: their Malaysian name and their Japanese name. You would probably want them to have a Japanese name if they ever want to go back to Japan. e.g. Ryusuke Hashim and Ryusuke Tanabe. Of course she could always change her name to yours and start a koseki under Hashim (for example). However most bi-cultural families I know maintain 2 last names.
Officially they will have to choose one citizenship (both Malaysia and Japan do not recognize dual-nationality) when 21 or 20 (age of majority in Japan is 20).
Finally, you would have to get 2 passports for them if you plan to live in Malaysia. They have to enter/exit Malaysia with their Malaysian passport and vice versa with Japanese passport and Japan.
