She was born in Fushami Castle. In the second year of her birth, Toyotomi Hideyoshi passed away. In accordance with Hideyoshi's last wish, Toyotomi Hideyoshi, the son of Mrs. Niyoshi, was betrothed to his cousins. In 1603, after the war of Sekiharu, his grandfather Tokugawa Ieyasu was appointed by the court as the general of the conquest of barbarians and founded the Edo shogunate. Then he married Chiki to Osaka Castle.

Chiaki married to Osaka Castle for twelve years, and did not have any children with Hideyoshi. Instead, Hideyoshi gave birth to a son and a daughter with her maid. In 1615, during the summer formation of Osaka, before Osaka City was about to be captured, Chiaki was rescued by the general of the Tokugawa family, Naomi Sakazaki. After escaping back to the Tokugawa family, she asked her elders to spare the lives of Mrs. Hideyoshi and Yodo, but her wish was not fulfilled. Both Hideyoshi and Mrs. Yodo finally committed suicide. In the end, only the life of Hideyoshi's daughter was saved. Hideyoshi's daughter later took Chiaki as her adoptive mother and was forced to become a nun by the Tokugawa side, and her name was Tian Hideyoshi

In 1616, Tokugawa Ieyasu passed away. At this time, Chiaki had been widowed for a year. Under the arrangement of her family, she was remarried to Bunto Tadako as his wife. Bunto Tadako's mother, Xiong Ji, was the daughter of Ieyasu's eldest son, Matsuhei Shinkang, so Chiaki's marriage to Tadako was also a kiss and a kiss. In 1617, the Bunto family was renamed from Ise to Himeji, and Chiaki also moved to Himeji Castle, so it was called "Harima Hime-kun", and the shogunate also gave her 100,000 stones as makeup expenses. In 1618, she gave birth to her eldest daughter Katsuji, and in 1619, she gave birth to her eldest son, Yuki Chiyo. It should have been a happy life, but Yuki Chiyo died in 1621. Five years later, in May 1626, at the age of only 30, Tadako The misfortune was not limited to this. In June of the same year, Tadashi's mother, Xiong Ji, passed away; in September, Chiaki's mother, Xiaodu, also passed away. After this string of unfortunate events, Chiaki returned to Edo Castle with her daughter Katsuji, and on December 6 (January 24, 1627) of that year, she shaved off her family's name, Waini, and was named Tianshuyuan.

After Chiji became a monk, she lived together with Seung-ji. The mother and daughter were placed in the Takeda Imperial Hall and received 10,000 stones as living expenses. However, in 1628, Katsuhie was arranged to marry Mitsuma Ikeda, the lord of the Toriha clan, and Chisuhie lived alone in Edo. In 1644, Mrs. Axia, the side room of General Tokugawa Iemitsu, gave birth to a son, Toramitsu (Tokugawa Tsunami). However, it is said that the child born at the age of 41 was unlucky, so she gave Toramitsu to Chiji for adoption. In 1666, Chiki passed away in Edo and was buried in Koishikawa Chuanyuin (located in present-day Bunkyo-ku, Tokyo), under the name "The Honorary Source of Tianshuin Matsuyama Sister."
