Almost unknown outside of Japan, Fuji Sanroku which means "at the foot of Mount Fuji", is produced in Fuji Gotemba distillery, opened in 1973 and owned by the Kirin Group. As iconic locations go, it's hard to beat this distillery's picturesque environ. The water source is rain and melted snow from the top of Mount Fuji. Maturation typically takes place in ex-Bourbon barrels.
Kirin has just announced in Dec 2018 that another of their blends will be discontinued but this, fortunately will still be produced.
