Industrial Standard –MARUKOME's High technolgy Factory

Miso is prepared by mixing steamed soybeans with Koji Yeast and salt, allowing the mixture to ferment for several months. Marukome uses the most modern production system in our state-of-the-art production line. A rice steam system, soybean steam system, and 120-ton fermentation tank are all part of the production line.


Soybean ProcessWe uses only non-GMO (genetically modified organism) soybean to produce quality miso at our factory. We rinse the soybeans and soak them in our large tank for several hours so that the soybeans become softer. Then we steam or boil the soybeans at our custom-designed cooking facility.

Rice ProcessWe sort, rinse and soak the rice for a few hours in a tank. After soaking, we steam the rice, then mix it with koji-starter and incubate it for two nights. The resulting product is koji.

Mix salt, yeast, and lactbacilli with Soybean and Koji.
