I would like to bring a musical instrument from my country to a Japanese friend via international postal parcel service. However, I would like to know about customs security in Japan. I mean to say is it better to give his address rather than mine for a smooth process? Or is it better to get in my name and give to him later?
Is it a gift to him? Then send it to him declaring it as a gift.
Is it for you to use and bring back? Then send it to yourself c/o him at his address. Declare it on your customs form when you enter the country.
