Tea is an important part of Japanese culture and is consumed daily. There are formal tea ceremonies that have specific etiquette rules around manners, dress, and appreciation of the tea and ceremony. Various types of tea are grown in Japan, with green tea being grown year-round and other varieties only seasonally. Tea leaves are processed differently depending on the type of tea. Merchants have traditionally sold tea in markets, often transported in kagos, maintaining tea traditions for over 800 years.
