Japan
Japan has a large industrial capacity, and is home to some of the largest and most technologically advanced producers of motor vehicles, electronics, machine tools, steel and nonferrous metals, ships, chemical substances, textiles, and processed foods. Agricultural businesses in Japan cultivate 13 percent of Japan's land, and Japan accounts for nearly 15 percent of the global fish catch, second only to China. , Japan's labor force consisted of some 65.9 million workers. Japan has a low unemployment rate of around four percent. Some 20 million people, around 17 per cent of the population, were below the poverty line in 2007. Housing in Japan is characterized by limited land supply in urban areas.
Agrivoltaic
In 2004 in Japan, Akira Nagashima developed a demountable structure that he tested on several crops. Since then, many field projects have been installed in Japan with a large number of crops (citrus fruits, peanuts, eggplants, cucumbers, cabbage, rice, vines, mushrooms ...) or livestock. Removable structures allow farmers to remove or move facilities based on crop rotations and their needs. Increasingly large plants with capacities of several MW have been developed since 2004 with permanent structures and dynamic systems. For example, a 35 MW power plant, installed on 54 ha of crops, was commissioned in 2017. The shading rate of this plant is 50%, a value higher than the 30% shading usually used on Japanese agrivoltaic power plants. Farmers cultivate, among others, ginseng, ashitaba and coriander. Soon, the island of Ukujima should host a solar power plant of 480 MW, part of which will be agrivoltaics. The project has been under study since 2013 and the various partners have signed an agreement for the start of construction in 2019.
