Hokkaido's Organic Bean "Suzumaru" is the Commitment of The Producers

This soybean is raised carefully for being organic, pesticide-free, and without chemical fertilizer cultivation.

Because we do not use pesticide, it takes a lot of time and effort to remove the weeds.

We work with 100-150 part-timers every year.

Also, we are sticking to the natural dyring process that becomes the characteristic of this bean.

The general beans that usually being distributed are those that have been heated and dried by the machines.

At the farm, we are utilizing the cold north wind blowing through the Tokachi Plain to dry and complete the beans.

Currently, there are a very few numbers of traditional soybean farmers that do the natural drying.

[Production Process] Mid May~Early June = Seeding→Early June~Mid August = Seasonal Weed Control→Early October = Harvesting→Natural Drying.)

The extraction of an organic, non-pesticide soybean contains 100% bacteria-beans. We are recommending the high quality organic beans of Kawashimaya, which even beginners do not fail to use it.
