OK I went to this shop:
http://www.dnano-online.com/shop/
From there I mastered to create an account and register my credit card (had to translate my name in japanese characters in the process btw

)
I ordered I dNaNo Murcielago and a few accessories, went to checkout and confirmed my order and wrote down the shipping address (France) in the observation field.
The website is done so that you can only register a domestic address (choose city and jap postal code through a list).
Then I received an e-mail:
"Thanks very much for you using KYOSHO ONLINE-SHOP. About your order "No.45216", sorry we can not send products to oversea. Of course, we can send to an address in Japan. If you have an address able to pick up, please tell us. In case you can not get it, please cancel this order. Now, it is in suspension. Please tell us what you do by e-mail. "
Now I am stuck. Don't know what do do
