Staples Mushroom Ambient Established export

Premium log-grown (genboku) dried shiitake from Oita, Kyushu, the heartland of Japanese forest-grown shiitake. Graded donko (thick, curled, premium) and koshin (thinner), it delivers concentrated umami for dashi and simmered/vegan dishes. Oita has actively exported since the 2010s; Sugimoto alone supplies wholesale and retail in ~15 countries (US, UK, Germany, Spain, Italy, France, Hong Kong, Taiwan, Singapore, Vietnam, India and more). Genuine Japan-grown commands a premium over commodity Chinese shiitake.
