Most popular Japanese dried Shiitake mushroom on Amazon Japan. Famous Japanese chef, Dr. Yukio Hattori, chose our Shiitake for his traditional Japanese New Year foods "Osechi." He is known as an expert commentator on the Japanese television show "Iron Chef." And his cooking school recommends our Shiitake and allow us to use his face on our products.

Our Shiitake are perhaps the only Kosher certified Shiitake that are 100% naturally grown, not using greenhouses. Sugimoto shiitake are naturally cultivated outdoors on special sweet sap oak logs. Moreover, our drying and packaging process keeps the moisture content to less than 9% which enhances the Shiitake flavor and VitaminD content. Sugimoto Shiitake promotes 100% natural and sustainable cultivation using only carefully selected local cultivators.

This Shiitake mushroom is called “Koshin” and is picked after the cap of the Mushroom blooms into an umbrella. It is more large and flat than the “Donko” Shiitake mushroom which is picked earlier while the cap is still in a bud form. Since Koshin is less thick than the Donko, it is easier and quicker to use requiring less time to rehydrate. Koshin is best used cut and in stir-fries, soups, sauces, where smaller pieces are used with other ingredients.

In Kyushu, Japan, we use Japanese Sawtooth Oaks to cultivate Shiitake mushroom. Japanese Chestnut Oak is famous for its sweet sap. Natural Shiitake mushroom grows with nutriment from only the logs and moisture from thick fog and rain. Nature grown Shiitake mushroom contains an abundant amount of "Guanylate.” Guanylate is a powerful Umami booster working with glutamate that brings an intense Umami flavor. Dried Shiitake mushroom has ten times more Guanylate than fresh shiitake.

Our products pass a yearly quality audit guaranteeing the consistency of the sourcing and production process of our Dried Shiitake mushroom. This Audit is conducted by the Japanese Ministry of Agriculture, Forestry, and Fisheries with the Japanese Consumers' Co-operative Union. (JCCU)
