Kabusecha refers to green tea leaves that have been shaded for enough time to create a strong umami flavor though not as strong as gyokuro. This is generally about two weeks of shading before harvest, and generally the shading is a direct covering for machines harvesting though some farms do handpick the leaf. Generally, it also refers to steamed leaves, so it may be considered a form of sencha, including fukamushicha if deep steamed or asamushicha if light steamed.
