I would like to order one too! Can send payment and a service charge, if you're willing to do it Kenji! Thanks for another fascinating look at the TdM!
I have made a rough calculation.
Probably US$10 can cover all the additional costs needed (PayPal fee, S & H in Japan, airmail postage, etc.) And if you would like the parcel to be registered, a bit more.
I will post here again when I am totally ready. Stay tuned
