Yes I sent a Peugeot classic tourist bike to Japan and here is how I did it. First the shipping charges are very high. It would have cost over $200 if you go UPS and almost that amount if you go US Postal in one big box by air. If your buyer is patient and wants to save a few coins you can pack the bike in two smaller boxes, (The USPS takes a BMX box as the largest they will handle). Of course I do not have to tell you to pack it very well with no parts moving around inside. Protect every fragile part like fenders, wheel hubs and the paint. Over stuff the box with foam or bubble wrap. I cannot over emphasize to make sure nothing is moving around inside the box that will smash against something else. Next you take it to the post office and ship the two boxes separately surface. This is truly the slow boat to Japan. It takes about 2-3 months but the difference in cost is enormous. The two boxes I sent cost me a total of $90. They arrived separately to the customer but did arrive in good condition. You will have to fill out some international customs paperwork and declare a value. This value is used to charge your customer duty on the bike which can also be substantial. Your customer should make the call on what they want you to declare the value to be because it is they who will pay. Also if you go this route the customer has to know that they will not insure the bike so there is risk. So long as you above board with the customer and set the expectations ahead of time this can be a savings to them. If they are willing to pay for Air then just follow the packing instructions. I do have some detailed instructions on packing, if anyone want me to elaborate just ask.
