The cave brewery was originally developed as a site for an underground factory manufacturing parts for military tanks around the end of World War II. In November, 1944, when the decision was made to evacuate Tokyo Doryoku Seizo Company, a semi-underground factory was built at the foot of the mountain and this factory was built next to it. It is said that about 20 military tanks were manufactured in the semi-underground factory by the end of the war but since the war was nearing its end, this underground factory came to an end without building tanks.
At Shimazaki Brewery, we use this cave that was once an underground factory as storage to age sake. Throughout the year, the temperature in the cave is an average of 10 degrees Celsius and it's the perfect temperature for maturing sake.
We provide Owners' Bottle Service where aged sake storage period can be selected from 5 years, 10 years and 20 years, and New Year's Bottle Service where we keep sake for under a year.
