Miss Hokusai is a 2015 Japanese animated feature film directed by Keiichi Hara (who is also known for directing Colorful). It is based on the manga of the same name by Hinako Sugiura and produced by Production I.G.
- Aloof Dark-Haired Girl: The only person who Oei is consistently expressive to is her blind sister. Otherwise, she's more aloof.
- Anachronism Stew: At times, the film transitions between traditional Japanese music and a rock/pop soundtrack.
- Art Shift: At several points when different characters tell stories.
- Cool Big Sis: Oei is her nicest and most emotionally expressive to her younger sister, O-Nao.
- Did They or Didn't They?: It's left ambiguous whether or not Oei had sex with Kichiya after he woke up.
- Disappeared Dad: Hokusai himself treats Oei as a mere assistant rather than a daughter, while he abstains from contact with O-Nao because of discomfort with her disability.
- Drag Queen: Kichiya, who works at a brothel.
- Geisha: Several can be seen as it is the time period when they were emerging.
- Jidai Geki: Set during the Edo period.
- Littlest Cancer Patient: O-Nao constantly needs assistance due to her blindness, then she dies from an undisclosed illness.
- Maybe Magic, Maybe Mundane: The anime uses several depictions of fantastic events to illustrate emotions such as frustration, fear, and determination. However, there are times when superstitious characters are subjected to these moments, making it come off as this trope.
- The Oldest Profession: Brothels and eroticism are a recurring topic.
- Outliving One's Offspring: O-Nao dies of an undisclosed illness and therefore Hokusai and his unnamed, estranged wife become this.
- Race for Your Love: A platonic example. Oei races to O-Nao when she gets an ominous feeling that the latter has passed away.
- Technician vs. Performer: Oei's erotic paintings compared to Zenjirô's. Oei's paintings are technically well-done but lack passion and charm, while Zenjirô's have a lot of technical mistakes but are much more popular because of how expressive and evocative they are.
- Umbrella of Togetherness: Oei runs into her father's student Hatsugoro, who she has a slight crush on, while walking in the rain. He offers to share his umbrella with her as he's going in the same direction, and encourages her to get in closer to him underneath it. Ultimately subverted as she becomes too uncomfortable with the situation and makes an excuse to leave.
