An'nan
Due to the so-called Nanban trade (hán tự: 南蛮貿易) in the 16th-17th century, fragments of Vietnamese ceramic were found in a northern part of Kyūshū island. Among them was a wooden plate with character showing the date 1330 on it. Whether the Japanese went to Vietnam or Vietnamese traders came to Japan or if it all went through China is not quite clear. Vietnamese history records showed that when Lord Nguyễn Hoàng founded Hội An port at the beginning of the 17th century, hundreds of Japanese residents were already there.
One of the more famous items is An'nan ware (安南), which was exported to Japan and used in Japanese tea ceremony although the high-footed bowls were originally used for food. The bowls had an everted rim, high foot, were underglazed with cobalt floral decorations, lappets above base, unglazed stacking rings in well and were brown washed on the base. The diameters can range from 9 to 15 centimetres. They were produced from the 16-17th century CE.
