The rich natural environment and changing seasons of the Japanese archipelago have fostered a unique fermentation culture since ancient times. Miso, soy sauce, sake, natto – these are not just foods, but living cultural heritage that the Japanese people have built over many years in a symbiotic relationship with microorganisms. The act of fermentation, through the work of unseen microbes, preserves food, enhances nutritional value, and creates deep umami, truly a wisdom of nature itself.
