Hitachi Odamai Rice

Our Tsukuba farm uses various farming methods in pursuit of delicious rice production.

Features of Hitachi Odamai Rice

Quality water from the Tsukuba foothills. Organic fertilizer made up of fermented fallen leaves minimizes the use of pesticides.
“We spare no time or effort to produce the most delicious rice.” That’s our motto.

Enjoy the sweet, sticky taste and plump, soft texture.
This is the ultimate Koshihikari, in terms of fragrance, luster, and stickiness.

Milk Vetch CultivationMilk Vetch Cultivation
In the past, this was a mainstream farming method, but
because it is time-consuming compared to the use of chemical fertilizers, its use has declined. The milk vetch increases nitrogen
levels in the soil, and plowing prior to rice planting produces
a farm-friendly fertilizer for the soil.
Special Cultivation MethodSpecial Cultivation Method
A national standard cultivation method. Fallen leaves
which have fermented over a two-year period are used as fertilizer. This provides plenty of oxygen and nourishment for
the soil, and allows rice to grow naturally.
Aigamo Duck Cultivation MethodAigamo Duck Cultivation Method
Free-range ducks eat weeds and pests, alleviating the need for pesticides. Their waste becomes a nutrient, making this
a safe method for the natural environment.
