The Foreign within Chanoyu (Tea Practice) Various imported items to Japan have made chanoyu, the practice of serving and partaking in powdered green tea, all the more interesting. Delftware has been used as tea utensils, and sarasa have been made into pouches and wrappers for utensils to be enjoyed behind the scenes. Attention is given not only to utensils such as tea bowls and tea containers but to their cloth bags (pouches) as well as wrappers for boxes that are usually not put out for display. Such care reveals the aesthetic sensibility of the refined.
