Customs fee (if any) are paid by the person
that receive the packet : It's a tax in the
receiving country. Not for sending something..

To avoid that the receiver have to pay taxes,
you have to say that the packet is a "gift"
and put a low enough value.

You mean you send a lot of things to Japan ?
So it's exactly the same thing.
