Japanese Tea or "ocha" has a characteristic fresh grassy taste and aroma, with hints of ocean mist from this island nation. Japanese green tea is world renowned. Tea was originally brought to Japan by Buddhist monks during the Song dynasty, after which Japan developed their own unique styles. They invented green tea powder, matcha, used in tea ceremonies, as well as perfecting roasted green tea, such as hojicha. The everyday Japanese teas are arguably sencha, a sweet green tea when brewed properly, and genmaicha, also called "popcorn tea", which blends loose green tea with roasted rice.
