Namban-yaki is the name of a type of coarse porcelain known in Japan as nanban-yaki, probably because it came from the South Seas. Its products include tea containers, tea pots, water jars, and kensui. The kiln location is not clear.
Luzon Tanai Baeken states that most of the Namban Island wares were produced in Lu Song (Philippines) and Aamagang (Macau), but these places were only collecting points for ceramics, not production centers. The Cantonese kilns of Ming Dynasty China exported ceramics of various sizes to the Philippines, Borneo, and other South Seas islands, so most of what is called Nanban ware is thought to have been produced in southern China. In addition, crude products from Annam (Vietnam) and Silla (Thailand) seem to have been mixed in, and some pieces with Indian inscriptions indicate that some pieces from India were also called Nanban ware. Most of them are purple-black stoneware, and the unglazed pieces have a robust taste, while some of them are glazed. According to the Manpo-Zensho, “Nanban ware is vulgar, just like Bizen ware in Japan. Nanban copies in Japan can be found in Bizen, Iga, Kyoto, Shigaraki, Tokoname, Seto, Tanba, Hagi, Karatsu, and Takatori.
