The plant factory is a facility that aids the steady production of high-quality vegetables all year round by artificially controlling the cultivation environment (e.g., light, temperature, humidity, carbon dioxide concentration, and culture solution), allowing growers to plan production.
By controlling the internal environment, plant factories can produce vegetables about two to four times faster than by typical outdoor cultivation. In addition, as multiple cultivation shelves (a multi-shelf system) are used, the mass production of vegetables in a small space is facilitated.
About 211 Plant Factories currently operate across Japan, cultivating lettuce, herbs, tomatoes, strawberries, and so on. The Plant Factory also has recently enabled the cultivation of some functional vegetables, such as lettuces with low potassium, making use of an environmental control system, a feature of the factory. Actions for large-scale production and entry into the market for such products are already being implemented. Furthermore, a demonstration project for establishing an industry cluster of large Plant Factories is now being considered.

Japan's cutting-edge technology contained in Plant Factories leads the world and facilitates business start-ups in Japan as well as other countries by Japanese enterprises including Japanese manufacturers, which have been starting to develop the Plant factories in the Middle East, Asia, Europe, and the U.S.
Taking advantage of the world-class technology of Japan's Plant Factories, METI will continue to conduct various policies regarding Plant Factories in close cooperation with the Ministry of Agriculture, Forestry and Fisheries.
