GE withdrew from Japan in 2007 as business deteriorated, but is returning in the wake of more attractive feed-in tariff prices post-Fukushima and the possibility of stable demand. The announcement was made at Japan's Wind Expo.
The GE turbine, which has a blade diameter of 103 meters, has been developed to comply with Japanese laws and regulations.
It will work during severe typhoons and has protection against lightning strikes. Along with severe turbulence, these are characteristics of the Japanese climate.
According to Japanese media reports, sales of the new turbine could commence as early as this spring.
Speaking at the event, GE vice-president for renewable energy Anne McEntee said:"With floating turbines and high penetrations of solar and wind there has never been a more dynamic time for renewables.
"As you look at Japan and how you think about the energy mix, Japan's overall energy diversity is key. As you look between 2011-12, with the repositioning of nuclear, you see the growth of needs for natural gas and coal.
"But we see an opportunity, and that opportunity is in renewables. Renewable energy is zero fuel usage, zero emissions and zero water usage. What you see is an opportunity for Japan."
