It wouldn't make him him the first child emperor. Plus, as @Lackadaisy said, what duties does the modern Japanese Emperor have anyways?

Apparently he 'appoints' the PM, and the Chief Justice of their Supreme Court.

Some representative functions aside he's actually important for religious stuff. To put it bluntly, he's to Shinto what the pope is to catholicism...

Well, this is the current heir. He would probably be able to be Emperor for a while.

religious mostly- iirc he is a bit like a jap patriarch in practice. i vaguely recall reading that during one of the shogunates child emperors...

He does well over 200 functions every year and works as an ambassador. His father was worshiped as a god. He does a lot, but IMO monarchy is...
