However, due to the FIT (feed-in tariff) program which was brought into effect after the Great East Japan Earthquake in 2011 and the declaration of carbon neutrality 2050 by the Japanese prime minister, the use of renewable energy has propelled in Japan. However, as much as hydropower generation is known to be the most clean and green energy, there is a lack of suitable locations for large-scale hydropower as well as the issue of high cost for small-medium hydropower in Japan, slowing down the movement. But with the help of government initiatives to move the country toward its green goals, the movement, though slow, is steadily on-going and will continue to increase.

During the above time period, the former Escher Wyss (now ANDRITZ Hydro GmbH) delivered more than 400 turbines to the Japan market, making the basis for ANDRITZ to be able to restart its Hydro business in Japan when the timing was right. Since the Great East Japan Earthquake in 2011, ANDRITZ K.K., the 100% subsidiary of the ANDRITZ Group, located in Tokyo, Japan, has been gradually expanding its sales activities for hydropower generation systems, following its biomass boilers business, as an option for renewable energy. With the support of the feed-in tariff system, the first unit of the hydroelectric power generation business was delivered and commercial operation started in 2017 as ANDRITZ K.K., although it was a small Pump used as Turbine power generation system which generated just 45 kW. Following this project, ANDRITZ Hydro's proposal activities for products and rehabilitation for large/ medium and small hydropower generation for the Japan market intensified from 2019, and the second and third Pumps as Turbines were delivered in 2019, with their commercial operation starting in 2020. In 2021, the order for the fourth Pump used as Turbine was received, and the orders for the first and second Francis turbines for Compact Hydro were also received. The Japanese hydropower market slowly opened its doors once again to ANDRITZ, a foreign company, and ANDRITZ K.K. has found the path to successfully restarting the hydropower business in the Japan market.
