This term refers to leaf tea pots that are said to have come from Luzon Island in the Philippines since the Muromachi period (1336-1573). However, it is incorrect to say that they originated on Luzon, and should be considered to have been brought over on Luzon-bound trading vessels. These tea jars include true jar, cheong xiang, lotus flower king, and other types of tea jars. They are thought to have been produced at miscellaneous kilns in Fujian, Canton, or southern China, and were exported directly or once to Luzon Island, and then imported to Japan as a secondary source. In the medieval tea ceremony, where it was customary to store leaf tea and decorate the tea pot, the tea pot had a high position that is unthinkable today, and it is likely that people sought it in precious imported items. The name “Seika” comes from the sake name “Seika” stamped on the shoulder, and it is known that this was originally a sake pot. Renka-oh is probably of the same ilk.
