Do you remember May 08, 2018, yes it’s birth date of our daughter “Kiara”. This post is about how to register baby birth in Tokyo Japan. Once you are discharged from the hospital the first thing you need to do is “Register baby birth” In city office (Your residing city). It is very similar to register yourself, once you move to the new city or you just landed in Japan. City office is the place to make your baby birth stay legal in Japan.
