This is a private cask bottling from Shizuoka for the Japanese retailer, Hasegawasaketen. It was distilled at the end of 2017 and and aged in ex-bourbon cask #026. This whisky was bottled in April 2021 as part of a limited release of 263 bottles.
 
Shizuoka have created a number of private bottlings during their early years, and they are proving quite collectible (and drinkable!).
