About Ishii Miso

Ishii Miso Co,Ltd
Ishii Miso Co,Ltd was founded in 1868 (the end of the Edo era) and is still producing miso by a unique traditional natural method.
Miso, soybean paste, is an essential ingredient in Japanese cuisine. We have miso soup every day and sometimes use it for other dishes. Miso is fermented food so it is very healthy.
Nagano Prefecture where Matsumoto is included is the top producer of miso (46%) in Japan.
Miso used to be made in homes. But now, many Japanese don’t know or find out how to make miso.
Wooden Barrels
We use wooden barrels to ferment miso, which is also unique. Normally the barrels are plastic or metal, but wooden barrels enable air to permeate so they are good for fermentation.
Many foreigners visit this brewery even though it does not appear in guide books and there is no English website.


Ferment miso over three years.
A special point of this Ishiimiso is that they ferment miso over three years. Normal cheap mass-produced miso is fermented only a few months in a factory. Their 3 year miso’s taste is much deeper and yummier than normal miso.

We have an English guide.
We have an English guide about fermented soybean paste and our company.
Let’s have a lunch

Let’s have a lunch
In Ishii Miso Co,Ltd, you can see inside the Miso storehouse and have a lunch containing miso soup, salad with miso dressing, rice balls, and even ice cream using our miso.

Try a miso ice cream!
The flavor of the fermented soybean paste and the thick vanilla taste fit fermented soybean paste ice cream very well.
