Born around 1800 as the second daughter of the ukiyo-e artist Katsushika Hokusai. Growing up at her father's side, she absorbed his technique from childhood — and Hokusai himself reportedly admitted she was more skilled than him. Her masterpiece "Yoshiwara at Night" (Museum of Fine Arts, Boston) depicts the Yoshiwara pleasure district under cover of darkness, capturing with extraordinary delicacy the contrast between the warm glow of paper lanterns and the surrounding night. This mastery of light and shadow rivaled the chiaroscuro of Western painting and was a startling achievement within the world of ukiyo-e. She remained by her father's side throughout his late creative period — including the "One Hundred Views of Mount Fuji" and "Thirty-six Views of Mount Fuji" — continuing to assist his work. After Hokusai's death in 1849 she kept painting, but her subsequent fate is wrapped in mystery. This "mysterious woman artist" has seen a remarkable revival of interest in recent years, with her name gaining international recognition as one of history's great women painters.

A genius who lived in the shadow of her father's immense talent and remained buried in history for too long. Yet the obsession with light in "Yoshiwara at Night" proves her inner artistic fire burned intensely. A mysterious woman of powerful individuality.

"Yoshiwara at Night" is a masterpiece that transcended the conventions of ukiyo-e in its handling of light. Increasingly recognized alongside her father Hokusai as one of the most important women artists in Japanese painting history, her international reputation continues to grow.
