Changing a child's name to their stepfather's name [Japan law]

2017-10-16 16:30:31

If a child has taken the name of their biological father, is there still a possibility to change the kid's name after their mother re-marries another man?

(according to Japanese law).

I assume changing the kid's name again is counter-intuitive, unless there are some serious reasons.

I am not familiar with the Japanese law regarding these matters, so I hope to get some éclaircissements.
