Japanese tea ceremony
Tea caddy (called natsume or cha-ire ).  A tea caddy is a special container that people put green tea powder in.  There are two kinds of tea caddies: natsume and cha-ire.  Natsume are short and have a flat lid and a round bottom.  They are made of wood. Sometimes natsume is called cha-ki. Cha-ire are tall and thin, and are made of ceramic.  Natsume and cha-ire are used in different ceremonies. Making weak tea (called usu-cha) needs natsume, and making strong tea (called koi-cha) needs cha-ire.
