Okinawa Sango Co.,Ltd. (Yatsugatake Kōgen Branch Office)

it has been 24 years since we first introduced hydrogen and mineral farming methods, and started the natural cultivation/farming of various grains, vegetables and fruits throughout Japan. At Coral Farm, we grow healthy crops and delicious vegetables without using any pesticides.
With this farming method, the presence of the microorganism actinomycetes in the soil increases and the rhythm of the natural circulation is gradually adjusted, through changes such as the lysing of the pathogenic fusarium.
