Miyoshi is a pioneer in this field and started mass production of virus free plants. We are the first company to succeed to produce and sell Gypsophila plants by tissue culture since 1975 in Japan. At present, we are producing many crops by this technique including Gypsophila, Limonium, Delphinium, Strawberry, Wasabi and etc. Currently, our commercial production is operated at the laboratories in Taiwan and India. The plants are imported back to Japan and also exported to our customers worldwide.
