Nihoncha means green tea produced in Japan. Green tea is made by immediately heating the tea leaves and drying them after harvest to prevent them from oxidizing, and there are various types of green tea – gyokuro, matcha, bancha, hojicha, genmai-cha, etc. At green tea factories around the Ohigawa area, each makes unique and original green tea in terms of umami, bitterness, flavor, and color (the color of green tea when steeped).
