Matcha powder for koicha and usucha is stored in special tea containers, known as chaire and natsume, respectively.
The formal Japanese tea ceremony, or chaji, involves the ceremonial preparation and presentation of koicha matcha. Dating back to 14th century Muromachi period of Japan, it continues to be practiced today as a representation of principles of harmony, respect, and purity and philosophies of wabi-sabi and ichi-go ichi-e.
