OK you are not going to like what I have to tell you!
The website differentiates between fragrances from:
(1) Les Salons du Palais Royal Shiseido and mentions that they can ONLY be bought from the boutique in palais royale in Paris. The price as of feb. 2005 is 95 euro for 75 ml. for all 21 fragrances in the collection.
and fragrances from:
(2) Parfums Serge Lutens. The price is 8,400 yen including tax for 50 ml of the eau de parfum and 11,550 yen for 50 ml for the more concentrated parfum. It mentions there are 13 fragrances in the collection and again, prices are as of february 2005.
There is no facility to buy these on-line in Japan let alone order internationally. There is a button to click which lists all those shops in Japan which sell these. It looks like a chain store called THE GINZA, mostly in various tokyo locations. Maybe you can call one of the shops and, if they speak english, ask them to ship to you but that is a loooooong shot. The country code for japan is 81 and you drop the initial zero when dialling from overseas. If the number starts with 03 it means the store is located in tokyo. Here are the stores and phone numbers:
