Windpower Monthly rating 3.5/5
Our rating is based on a combination of project pipeline, political and policy support, investor confidence and structural readiness of the country in terms of grid infrastructure, permitting process and local supply chain.
Forecast of installed and operating wind power capacity based on the latest statisitics and measured against the Windpower Intelligence database.
The government is broadly supportive, obliging utilities to buy renewable power under feed-in tariff laws, and has removed an 820MW limit on offshore wind development. However, it has yet to set a new target.
Japan expects 1.7% of its power to come from wind by 2030.
However, it is still heavily reliant on coal, oil and gas, but moved away from nuclear since the 2011 Fukushima disaster.
The country also has tough environmental impact assessment procedures, concerns about grid accessibility, and no mechanism for consumers to sign direct power purchase agreements with wind power generation companies.
Analysts expect such regulatory barriers to be removed.
The country is set to commit to additional offshore capacity. A bill requiring designated offshore wind project construction zones to be set up and 30-year occupation leases for developers is due to be discussed in parliament.
JAPAN Improving its position in the future depends on the government's efforts (and success) in deregulating the power grid, easing environmental testing burdens and committing to an ambitious renewable energy target ahead of the COP 21 UN climate change summit
JAPAN: Pressure likely to increase on power companies to increase sustainable energy on the grid, while expanding offshore into ever more ambitious hybrid technologies, following the government's selection of four test sites for wind and ocean-based power.
JAPAN: No longer judged ineffective, policy support for offshore projects in Japan will see the country slowly embrace renewables.
JAPAN: The prospects for wind power in Japan during 2014 can only be described as poor.
JAPAN: The solitary wind turbine floating in the Pacific Ocean, 20 kilometres from Japan's eastern coast, has become something of a poster boy for the wind industry.
Vestas has introduced a new model to its 4MW platform designed to withstand extreme weather events including high wind speeds and turbulence in lightning storms.
Japan installed 261MW last year, up 61% year on year on 2017's additions, but lengthy environmental impact assessments (EIAs) continue to hinder development, according to the country's wind power association (JWPA).
Hitachi will stop producing its own turbines and instead focus on distributing Enercon machines in Japan and overseas, expanding a 20-year-old collaboration agreement with the German manufacturer.
Ørsted has entered the Japanese offshore wind sector by signing a memorandum of understanding (MoU) with Tokyo Electric Power Company (Tepco) to work jointly on offshore wind projects.
Japanese technology giant Hitachi has announced plans to acquire an 80.1% stake in ABB's power and grids business for an estimated JPY 704 billion ($6.4 billion), with the option to buy the remainder.
