exists today as the Koxinga Child Birth Stone Tablet (鄭成功兒誕石碑), which is 80-cm tall and 3-metre wide, and submerged during high tides. According to legend there was a whale washing ashore and a storm was he was born. Being in her early twenties, and being older than Zheng Zhilong have raised the possibility Tagawa was a widow before she met Zheng since it was unusual for a woman to not be married by this age. Tagawa was the first woman Zheng fell in love with and they were viewed as having a common-law marriage already. However, the group of traders working with Captain China wanted to arrange for a Chinese woman, Lady Yan to marry Zheng Zhilong. After the birth of Koxinga, she was still visited in Japan by Zheng Zhilong sometimes according to sources from their time. She had another son named Shichizaemon in 1629 and gave him her family's surname, Tagawa. Sources say that Zheng Zhilong was the father and that he visited Hirado to impregnate her with Shichizayemon and that he received the surname Tagawa because he was adopted by Tagawa Matsu's parents but others say Shichizaemon was the product of an unknown Japanese man which is why he was given Tagawa's surname and not Zheng.

Koxinga was sent to live with his father in China in 1630. The Taiwan Waiji (臺灣外記) says "every night he would face east and look to his mother, hiding his tears." Tagawa Matsu did not come because she did not want to abandon Shichizaemon and was not willing to send the younger Shichizaemon on the dangerous ship ride. In 1645, she was reunited with Koxinga by moving to Quanzhou, Fujian. She moved to Anhai despite the Japanese ban on leaving. In 1646, when Koxinga was away fighting the Manchu Qings, the city was invaded by the Manchus. Koxinga, upon hearing of the invasion, immediately returned to Quanzhou, only to
