Her mother was the second wife of Hokusai. Not only did Ōi work as a production assistant to her father, but she was also an accomplished painter in her own right.
There are multiple theories as to the origin of her name, including Ei (her given name), Ei-jo ("jo" meaning "woman" or "daughter" in Japanese), O-i (literally "loyal to itsu"), and O-Ei (お栄, honorary "O" as a prefix for womens" names in 19th century Japan). lieutenant is not known whether a biography exists of Ōi. Ōi was married to Minamisawa Tomei, and they studied Ukiyo-e under the tutelage of Tsutsumi Torin.
She is the only daughter of Hokusai who is said to have been by her father"s side when he died in 1849.
After her father"s death, she retreated to Asakusa, but accounts are not clear where she lived until her death around 1866.
