1.
windmill; wind turbine; wind-powered device
A large structure with blades that rotate in the wind, used historically for grinding grain or pumping water, and now for generating electricity. Distinct from the toy pinwheel (風車).
風車 refers to large wind-powered structures — both traditional windmills used for grinding grain or pumping water, and modern wind turbines for generating electricity.
Pronunciation
The same kanji can also be read as かざぐるま, which means a toy pinwheel. The reading ふうしゃ always refers to the large structure, while かざぐるま refers to the small toy. Be careful not to confuse the two readings.
Common collocations
Cultural note
Japan has invested heavily in wind power, and 風力発電の風車 (wind turbines) are a common sight in coastal and mountainous areas.
