Tagawa Matsu (田川マツ; 1601–1647) or Weng-shi (翁氏), was the mother of Koxinga, daughter of Tagawa Shichizaemon (田川七左衛門), a vassal of Hirado Domain. She was a Japanese who lived most of her life in the coastal town of Hirado, then later migrated to China. Giving birth by the stone Tagawa Matsu was a Japanese woman from a samurai family in Hirado. Tagawa met and married a Han Chinese Hoklo named Zheng Zhilong from Nan'an, Fujian, China who frequently traded with the Japanese in Hirado. They fell in love with each other and married. Zheng Zhilong was said to be "very good looking" and when he first came to Japan he was 18 years old. Tagawa was a few years older than Zheng and she was in her early twenties when they met. There are different accounts on how they met. In one of them she, along with other Japanese girls from Samurai families, were waiting on the Daimyō Matsuura at an evening party when she met Zheng. The meeting may have been deliberately arranged by Matsuura or her parents to help marry her off to a foreigner. In another he met Tagawa while talking to girls along the beach in Hirado. In another, Tagawa, an Ashigaru's daughter, was given to him by the daimyō. Another one by in Guangyang Zaji (廣陽雜記) said that Tagawa was a widow when she met Zheng. It said that Zheng Zhilong fled to Japan when he was young and worked as a tailor. He lost his life savings of three coppers on a road and was looking for them but couldn't find them. He started crying but a Japanese widow who was standing inside the gate of her house saw him and asked him what was wrong. Zheng Zhilong told her and then she said to him "With your skill, you could easily make 3 million coppers, how could you arrive at this situation over 3 coppers?" She then invited Zheng to spend the night with her and they gave themselves to each other. She gave birth to Koxinga during a trip with her husband when she was picking seashells on the Senli Beach, Sennai River Bank (川內浦千里濱), Hirado. She gave him the Japanese name Fukumatsu.
