If the total price the buyer has to pay is reasonable and the risk is minimal, then you shouldn't have much trouble selling from outside of the US. The only other factor would be how long it would take for the buyer to receive the item, that may deter a few people.
I don't know if Paypal offers you any seller protection in Japan, but I know the US terms of service stipulates that First Class Mail International (usually the cheapest shipping method from the US) is not covered by their seller protection because the tracking info isn't adequate. So realistically, a person would need to use a higher priced expedited service that provides detailed tracking in order to have any Paypal protection. Again, I don't know if that pertains to you in Japan or not. Pretty much everything I've sold internationally has cost between $30-$40 to ship and pretty much everything I've sold within the US has cost between $10-$20 to ship, since I always insure my packages. If you choose not to insure your packages, you'll just be assuming all the risk if it does get lost in the mail.
I don't know all the ins and outs of the international trade agreements, but I'm pretty sure that if a person in the US buys a knife from a person in another country, there is no import tax if the knife was originally manufactured in the US. That's about as far as my knowledge goes on that subject lol.
