Japan is an island country in East Asia. The country has a total of 6,852 islands extending along the Pacific coast. As of 2018, Japan's territory covers 377,973.89 km2 . It is the largest island country in East Asia and its capital is Tokyo. Japanese is the official language in the country.

About 73% of Japan is forested, mountainous and unsuitable for agricultural, industrial or residential use. As a result, the habitable zones, mainly located in coastal areas, have extremely high population densities with a population of 126.8 million in 2017. Japan is substantially prone to earthquakes, tsunami and volcanoes due to its location along the Pacific Ring of Fire.

Japan is the third largest national economy in the world and is highly developed. The country’s main imports are machinery and equipment, fossil fuels, foodstuffs, chemicals, textiles and raw materials for its industries. Its role in the international community is considerable being a major aid donor and a source of global capital and credit.

Resource-poor Japan is dependent on imports for more than 90% of its energy, which affects its energy security. Prior to the Fukushima Daiichi Nuclear Accident, power generation was dominated by fossil fuels (60%) and nuclear (30%). Post the accident, a big increase in fossil fuel imports for thermal generation has lead to Increasing electricity prices, a high dependency on imports, and an increase in greenhouse gas emissions.

Japan is looking to expand its renewable energy use to reduce its dependency on fossil fuels and secure energy supply. Solar power in Japan has been expanding since the late 1990s. The country is a leading manufacturer of photovoltaic and a large installer of domestic PV systems with most of them connected to the grid. Japan has an insolation of about 4.3 to 4.8 kWh/(m2·day). By 2030 Solar PV is expected to comprise 33% of generation from renewables and attract 62% of government incentives for renewable generation. In 2018, the government adopted a new basic energy plan, which calls for generating 22-24% of the country’s electricity by renewable energy sources such as solar and wind power, 20-22% by nuclear power and 56% by thermal power in 2030.

To combat the lack of land available for solar farming, Japan has also built the world’s first floating solar plant in Aichi Prefecture in central Honshu. The country’s many inland lakes and reservoirs house 73 of the world's 100 largest floating solar plants and account for half of those plants’ 246 MW of solar capacity. Many of these plants are small-scale and are helping kickstart distributed power generation.

Fiscal incentives include feed-in-tariffs for solar and other renewable energies since 2012. The FIT scheme requires electric power companies to purchase electricity produced by firms and households using solar power, wind power and other renewable energy sources at fixed rates for long periods.

Electricity and Gas Market Surveillance Commission (EGMSC)

The EGMSC is a highly independent committee directly governed by the METI Minister to ensure the integrity of the electricity, gas and heat supply markets and the neutrality of the network divisions. It has the authority to oversee the electricity, gas and heat supply markets by conducting audits of the business and accounting of utilities, requesting reports, conducting inspections, issuing adjurations for business improvement and regulated retail prices and making suggestions to the METI Minister on the approval of wheeling charges and registration of retailers.


Institute of Applied Energy (IAE)

IAE conducts research activities form a technological standpoint covering all energy aspects in response to the changing social needs.


New Energy Foundation (NEF)

NEF is oriented towards the dissemination and promotion of RE and the establishment of new energy systems such as Fuel cell and Hydrogen. The Foundation is engaged in various activities such as recommendations to the government, information gathering and research studies, promotion and enlightenment, human resource development as well as international cooperation.


New Energy and Industrial Technology Development Organization (NEDO)

NEDO plays an important part in Japan's economic and industrial policies as one of the largest public research and development management organizations. It has two basic missions: addressing energy and global environmental problems, and enhancing industrial technology.


Federation of Electric Power Companies (FEPC)

In 1952, the nine electric power companies established the Federation of Electric Power Companies (FEPC) to promote smooth operations within the industry. Since then, FEPC has played an important role as a base for close communication between the electric power companies and as a forum for exchanging views to create the electric power industry of the future. Moreover, FEPC undertakes various activities to ensure stable operations of the electric power industry, with awareness of its role in the energy industry of Japan.


Ministry of Environment (MoE)

The MOE has jurisdiction over the Environmental Impact Assessment Act in general, and the Minister of Environment can state his opinion on the construction of power plants from an environmental viewpoint. In 2015, the Minister of Environment objected to some construction projects for coal power plants due to the national policy to reduce carbon dioxide emissions. It is responsible for countermeasures against global warming.


Japan Renewable Energy Corporation

Japan Renewable Energy Corporation's main objective is to provide sustainable energy resources to all customers through international best practices. 


Japan Photovoltaic Energy Association (JPEA)

JPEA aims to contribute to the prosperity of the Japanese economy and to the improvement of the national life by focusing on the establishment, deployment and promotion of the utilization of PV power generation systems. 


Agency for Natural Resources and Energy (ANRE)

The ANRE is an affiliated agency of the METI responsible for most of the electricity-related policies, including the drafting of the Energy Basic Plan and the energy mix plan, securing the stable supply of electricity nationwide by the stable supply of fuel and other resources, promoting the installation of renewable energy power plants, designing and creating the regulatory system for the electricity and gas market and considering nuclear policies.
