Customs duties/import taxes, if applicable, are between the buyer and Japan customs. Not your concern. The buyer may ask you to declare a lower value on the shipping document so they pay less customs duties/import taxes. Its no skin off your nose to do so, as long as the buyer is ok with the insured amount being lower. International shipping is running smoothy again after experiencing some hiccups last year. In recent months, I've received multiple packages here in Japan from Amain Cycling in the US. All received in a timely manner.
