Summer Days with Coo

The film does not include any LGBTQ+ characters or those with non-binary gender identities. The story focuses on a friendship between a child and a mythical creature within typical social structures.

The story follows a traditional male-centric coming-of-age narrative. It avoids overt sexism but does not challenge existing gender hierarchies or dynamics.

The setting and cast reflect a homogeneous rural Japanese population. While the Kappa symbolizes a underrepresented cultural remnant, the human characters lack multi-ethnic diversity.

The narrative emphasizes folklore and a nature-centric worldview over state or religious morality. It explores the tension between childhood innocence and institutional authority.

There are no prominent depictions of physical or neurodivergent disabilities. Such traits do not serve as central drivers for the characters or the plot.
