Oita is Japan’s foremost producer of dried shiitake mushrooms, and its high-quality log-grown shiitake are a signature product of the prefecture, prized across the country. In Oita’s forested, mountainous interior, shiitake are traditionally cultivated the natural way — grown on logs of kunugi (sawtooth oak) left in the cool, humid forest, a slow method that produces mushrooms of superior flavour and texture. The most prized grade, thick-capped ‘donko’ mushrooms harvested in cold weather, are especially valued. Rich in umami, dried Oita shiitake are a cornerstone of Japanese cooking, used to make dashi stock and add deep savoury flavour to dishes. Visitors can learn about the cultivation, taste shiitake dishes, and buy premium dried mushrooms as an excellent, long-keeping souvenir. A taste of Oita’s rich forest bounty, shiitake are a rewarding local speciality to discover.

Tips
Buy premium dried ‘donko’ shiitake as an excellent, lightweight and long-keeping souvenir, and remember to rehydrate them in water before cooking to release their deep umami. Use the soaking water as a rich dashi stock, look for them at markets and roadside stations across rural Oita, and pair shiitake dishes with the region’s other local foods.
