Answer:

You need to say in clearer English.

When someone lives in Japan under proper visa, his spouse and children can live in Japan under dependent visa. So it's possible.

Addition:
You can't get dependent visa if you are not his wife. Only children can get it. Immigration officials are now inspecting it. You will see the result later.
