Welcome to the SolidPerfume website. It's great to have a new member. Most of your questions have been answered by other members. The new Estee Lauder solids can be purchased from the following stores:
Bustier – Saks Fifth Avenue
The Lighthouse and Steamboat – Neiman Marcus
If you click on the yellow tab at the top of the page labeled STORE LOCATIONS you will find names and telephone numbers for these stores.
I live in the United States so I don't know if they ship to Japan. But you can EMail ask them.
Hope this helps you out.
