The renewable energy is expected after the nuclear accident. However, since the costs of renewable energy are higher than others, environment policy is required, and it influences on the management. Feed-in tariff (FiT), in which electricity produced by renewable energy sources is bought by the electric utilities at above market prices, was introduced in Europe. It was very effective to promotion the solar cell installation. Although the Feed-in tariff with Japanese Diet approval will become effective in Japan, could it revitalize Japanese solar cell industry? Based on the cases of FiT in Spain, Germany etc., it is analyzed that the influence of FiT information on Japanese solar cell industry.
