It is a way if you go to Japan or if you have friends, business partners or collaborators in Japan. I do not know whether it can be put in one box, as it depends on the carrier.
1: Select a carrier
FedEx, DHL, Yamato Transport (There is an art delivery service within the group company that specializes in the transportation of art objects), Japan Post (EMS = international mail)
2: Pack
You need to pack it yourself in a strong box such as a wooden box.
3: Write the shipping address
4: Bringing it to the carrier and contacting the shipping address
2, 3, 4 vary a little depending on the delivery company. Shipping costs and safety also vary from carrier to carrier. There is information that FedEx, Yamato Transport, and Japan Post are likely to arrive. Good luck!
