Katsushika Ōi
Katsushika Ōi (, – ), also known as or Ei-jo, was a Japanese Ukiyo-e artist of the early 19th century Edo period. She was a daughter of Hokusai and his second wife. Ōi was an accomplished painter who also worked as a production assistant to her father. Biography. Ōi's birth and death dates are not known, although it is believed that she was born in 1800 and died around 1866. She was a daughter of the ukiyo-e artist Katsushika Hokusai (1760—1849). Hokusai was married twice; the first marriage produced a son and two daughters, and the second , to a woman named Kotome (), resulted in a son and one or two daughters. Ōi studied her craft under her father's guidance as his apprentice. She also studied under Tsutsumi Torin III (1789—1830) who was a fellow painter and printmaker. This is where she met Minamizawa Tomei (also known as Tsutsumi Tōmei), another one of Tsutsumi Torin III's students, and married him in 1824. Their marriage did not last long, for only three years later they divorced. It is rumored that their marriage ended as a result of Ōi's criticism of Minamizawa Tomei's work, claiming he  was a terrible artist, and laughing at him for it. Ōi thereafter went to live with her father again, and assisted Hokusai with his artwork, and took to producing her own as well. In 1828, Kotome, Ōi's mother died, leaving her to care for her now sixty year old father. Neither of whom cared about housework or maintaining their home, their time was occupied by their work, both of them painting and printmaking alongside one another in an unkempt household. Despite her father's fame, Ōi too managed to make a name for herself. In Hokusai's family, his  daughters were expected to tend to their father and assist him in his workshop until they're married off and required to tend to their own husbands. And while Miyo, Tatsu, and Nao, Ōi's sisters, suffered this fate, Ōi never remarried, allowing her to move back in and work on her craft. Hokusai himself noted his daughters' talent when it came to depicting beautiful women, remarking on her technique as forces to be reckoned with, forces he himself could not compete with. Other artists at the time like Keisai Eisen regarded her as accomplished, for despite being a woman , Ōi garnered a reputation as a skillful artist after her father. Works. Ōi is known to have excelled at handwriting and in "bijin-ga" paintings of beautiful women. The following is a selected list of her works. She has also been credited as an illustrator for the following books. Aside from drawing and painting, Ōi also made "keshi ningyō" dolls and sold them to earn a living. Legacy. Few of Ōi's works are known: amongst them, a few "nikuhitsu-ga" paintings, the illustrations to the book "Onna Chōhō-ki" (, 1847) by Takai Ranzan (), and no prints. Canadian novelist Katherine  Govier wrote a first-person novel about Ōi titled "The Ghost Brush" (2010, also titled "The Printmaker's Daughter"). The story of Ōi was adapted to comics as "Miss Hokusai" (1983–87), which had an animated movie adaptation in 2015. The story tells of the outspoken O-Ei, daughter of the famed artist Tetsuzō, for whom she sometimes paints uncredited. The film won numerous awards. Makate Asai based her novel on the life of Ōi; it was published in 2016 after serialization in 2014–15, and an NHK television adaptation of it titled "Kurara: Hokusai no Musume" (""Kurara: Hokusai's Daughter"") appeared  in 2017, starring Aoi Miyazaki.
