Japan installed 26MW of new wind capacity in February, compared to just 63MW in the 10 months from April 2012 to the end of January, according to calculations based on statistics from the country's Agency for Natural Resources and Energy (ANRE).

Data from the Japan Wind Power Association (JWPA) shows the jump in capacity was partly due to the installation of eight 2MW Hitachi turbines to expand the Kamisu wind farm, on the coast of Ibaraki Prefecture, east of Tokyo.
