Accidentally yesterday I watched 'Miss Hokusai' about a daughter of the artist - she was a painter herself. The (animated) movie can be seen as a series of episodes, with the relations between Katsushika Ōi and her father being one of the subjects presented. From a quick glance at the (English) Wikipedia page about Hokusai I could spot some divergences compared to the movie. Anyway, I enjoyed the move quite a bit.
