Okko's Inn is a 2018 anime movie created by Madhouse and directed by Kitarô Kôsaka. It is based on the Japanese novels Wakaookami Wa Shogakusei (The Young Innkeeper Is a Grade Schooler!), which got an anime adaptation in Spring 2018. While based on the same property, the series and movie are unrelated.
The movie focuses on Okko, who, after losing her parents in a car crash, is sent to help run her grandmother's Japanese inn. It's not long before she meets mischievous ghosts, the entitled rival innkeeper Matsuki Akino, and several customers, which is a lot to handle, especially when Okko is convinced her parents are still alive. At Hananoyu Inn all are welcome, and Okko learns that helping others can help herself as well.
This movie contains examples of:
- Beware the Nice Ones: Uribo is basically a nice ghost, but when he sees Okko being insulted, he rushes to her defense by either insulting said offender or, in Matsuki's case, draws mustaches on her face.
- But Now I Must Go: After Okko learns all she can and comes to terms with her parents' death the ghosts leave to be reborn in human bodies.
- Coming-of-Age Story: The story is about Okko learning to come to terms with loss, and also to be more self-sufficient and helping others.
- Only Known by Their Nickname: Okko's real name is Oriko Seki but she mainly goes by Okko.
- Ojou: Matsuki runs a luxurious inn and acts like a bratty princess.
- Ryokan Inn: The backdrop of this series is a resort town, with most of the cast involved in the operation of these. The title of the original novels refers to the fact that Okko works at one.
- Unfinished Business: The ghosts Okko encounters all have ties to the living world, and are able to move on once Okko helps them and herself.
- You Can See Me?: Suzuki, Uribo and Miyo are ecstatic that Okko can see them, and it's one of the reasons they prefer her inn over Matsuki's.
