Shiitake mushrooms are one of the essential ingredients in Japanese cuisine. Especially in their dried form, they have been enjoyed since the Edo period, used for making dashi (Japanese cooking broth) and in simmered dishes such as nimono.

When fresh shiitake are dried in the sun, a compound called ergosterol converts into vitamin D, making them an excellent plant-based source of this nutrient. Drying also intensifies their savory umami flavor, enhances their nutritional value, and greatly extends their shelf life. For this reason, dried shiitake are often preferred in traditional Japanese cooking. When rehydrating, don’t discard the soaking liquid—it’s rich in flavor and can be added to soups and sauces for extra depth.

Shiitake mushrooms are naturally low in calories yet high in dietary fiber, making them a good choice for those managing weight or supporting digestive health. They also contain unique compounds such as eritadenine, which research suggests may help lower cholesterol levels and support cardiovascular wellness.

In Yakuzen, shiitake are valued for their ability to nourish Qi and support the Spleen and Stomach, which are central to healthy digestion and energy production. They are often recommended for symptoms like poor appetite, bloating, or fatigue caused by sluggish digestion. By gently strengthening the digestive system and improving Qi flow, shiitake help restore balance and vitality. However, moderation is important—overeating may cause digestive discomfort in some people.
