Here's a bottle of 2006 GlenEbisu, Yoichi 10, Suntory Single Grain, Yamazaki 12 and Nikka Single Cask 10.
Suntory Single Grain, Nikka Single Cask 10, Yamazaki Single Malt and Hakushu Single Malt.
All of the Single Cask, Single Grain and both the bottles with Japanese labeling only are bottlings only available from the distillery.
I personally bought the Nikka Single Cask 10 because I liked it so much and if you can read the line below the English labeling, it shows that it's from Sendai/Miyagikyou distillery in Miyagi, just inland from where the tsunami hit last year.
Any further information I can give just let me know.
