What is ISOKURA?

ISOKURA SAKE BREWERY was established in INADA, KASAMA city, IBARAKI JAPAN in 1868.
"Inada" produces beautiful spring water that comes from surrounding mountains through the bedrock.
And, the district of "Inada", which means rice- field, and is also where we are located, has been known as one of the best rice-producing areas in Japan as its name indicates.
There are many granaries known as "KURA" in our yard, we came to be called "ISOKURA" in combination with the family name "ISO".
Blessed with such good rice and water, our ancestors began making sake in the "EDO age" period. Having succeeded in producing of our original sake, called "INASATO" named after the rice-producing village, we started the brewery business.

Water & Rice

"SEKITOSUI Water" (Rock- Filtered Natural Soft Water) is what we use to make our sake.
Inada water is naturally purified by bedrock of granite, which is found throughout our region. The quality of this soft water is extremely good and its quantity is bountiful.
"Local Rice" is a very important element. It is what ISOKURA is based on.
We consider that rice quality is more important than location where it's made and the brand of rice.
However, we know the key elements to our taste, more than anyone else. (The most important elements are "pure starch" and " rich minerals"!)
For that reason, we are growing the rice in the local by ourselves.
