■The #1 Producer of Shiitake in Japan!・Oita Prefecture Dried Shiitake Mushrooms.
The secret of delicious Shiitake Mushrooms from Oita.
▼ Specializing in Bed Logs.
There are two methods of cultivating Shiitake mushrooms, the first is Bed Log Cultivation, which involves felling trees in the forest and directly inoculating them there with the Shiitake mushroom fungus, which will generate Shiitake mushrooms in a natural outdoor environment. The other method is Mushroom Bed Cultivation which uses a mushroom bed (an artificial medium using a woody base like sawdust, mixed with nutrients such as rice bran) which produces mushrooms in an indoor artificial environment.
Nearly all the fresh and dried shiitake mushrooms cultivated in Japan and China are cultivated by the "Mushroom Bed Cultivation" method, using an efficient artificial environment.
However, dried shiitake mushrooms from Oita Prefecture are grown only by the "Bed Log Cultivation" method, in a natural outdoor environment that produces mushrooms that are thicker and chewier than those grown in mushroom beds, the taste is considered more "Umami" and closer to that found in naturally growing mushrooms.
▼ Producing 50% of the Domestic Market Share.
Domestic mushroom production is on a downward trend, due to economic problems and natural disasters, however, in Oita, the government is working with mushroom producers to overcome this crisis.
In addition to ensuring food safety and reliability, we continually make efforts to maintain domestic production in order to ensure the availability of authentic Japanese food.
From 1905 to 1949, the nationwide share of mushroom production from Oita prefecture was 15 to 25%, but it has continued to rise every year and is now about 50% of the domestic share.
▼Presented to the Imperial Family and as a Sumo Winning Prize.
Shiitake mushrooms produced in Oita prefecture have been a given a high rating nationwide both for quality and quantity, and have been presented to each of the Imperial Houses by the Governor of Oita Prefecture, every year since 1981.
