Product Advantage
1. Flat and easy to use, with a thin-shaped cap. This Shiitake mushroom is called "Koshin" and is picked after the cap of the Mushroom blooms into an umbrella. It is larger (42-75mm) and more flat than the "Donko." It is easier and quicker to use than Donko, requiring less time to rehydrate. Please see "attached" recipes for instructions and other delicious Shiitake recipes.

2. Premium Forest-grown Shiitake Mushrooms naturally cultivated outdoors on special sweet sap oak logs. Our Shiitake are grown 100% by local farmers on Kyushu, a Southern Island of Japan. Our Shiitake has the most natural Vitamin D, 9680 IU/100g.

3. Japan's most famous cooking school, Hattori Nutrition College, recommends our Shiitake. We minimize Shiitake's moisture content to less than 9% to preserve a premium taste and quality. Our Forest-grown Dried Shiitake is recognized as the best tasting and provides the most Umami.

Sugimoto Premium Forest-Grown dried Shiitake is cultivated locally by 600+ traceability managed growers. The growers use a 1,000-year-old Japanese approach to grow sustainable Sweet Sap Oak (Sawtooth Oak) Tree logs. Our Shiitake are grown on Sawtooth Oak which are in Japan recognized as producing the best-tasting and textured.
Naturally, Forest-grown Shiitake has a distinct and deep flavor with an outstanding firm texture. Forest-grown Shiitake grows slowly when cold winds and natural sunlight quickly dried moisture provided by rain and fog. Each Shiitake has it's own unique climatic exposure, which produces distinctive shapes and colors.
Japanese famous 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." His cooking school recommends our Shiitake and allow us to use his name on our products.

Our Shiitake is perhaps the only Kosher certified Shiitake that are 100% Forest-Grown. The most strict Orthodox Union approves our factory. ( https://oukosher.org/companies/sugimoto-co-ltd/ )
Kosher certification means Pure Shiitake as with no chemicals or insect egg.
The forest undergoes a 15-years life cycle. In the spring, seedlings will grow from sawtooth oak stumps. Thus, the oak trees on the mountain will regrow after a period of time. Very Sustainable. We use a far-infrared drying approach, which minimizes moisture to less than 9% (others are 12%+) to preserve a premium taste and quality. Our Shiitake has the most natural Vitamin D, 9680 IU/100g, by UVB exposure.

Forest-grown Dried Shiitake contains the largest amounts of Guanylate, which enhances the Umami of Glutamate and creates a much more intense Umami taste. The most abundant amino acids in the natural world are Glutamate. Umami, produced by Glutamate, has a characteristic of becoming seven to eight times stronger through Guanylate of Dried Shiitake. The drying process breaks the Shiitake's cell membrane, and the rehydrating produces Guanylate. Dried Shiitake is a natural Umami booster for home cooking. Forest-grown Dried Shiitake provides the most and deepest Umami flavor.

Tips for Rehydration
For the best results, please soak in cold water for 24 hours in the fridge. To reduce soaking time, take out the Shiitake one hour after you started soaking, remove stem, soak for another hour until soft.

Store dried Shiitake mushroom at room temperature, away from heat and moisture.
