The cup features golden plaice on the base of the vessel, with a special silver-coat finish on top of it. Nakatsugi (cylindrical shape) : A cup type for light green tea. There’s a joint in the middle of the cylindrical shape which is why it got its name. Usuchaki: Cups for light green tea are often being referred to as “natsume” (jujube), but only the jujube shaped vessels are actually called this way. All other vessels have their own specific name.
