Yamaguchi-kun Isn't So Bad Movie Opens at 6th Place in Japan

Yamaguchi-kun Isn't So Bad's highly anticipated live-action film entered the Japanese box office at 6th place during the week of June 11, 2026. According to Anime News Network, while the film did not have a strong opening week, it shows continued interest in manga adaptations.
At the top of the box office list, Super Mario Galaxy Movie ranked 2nd, while Detective Conan: Highway no Datenshi held its position at 4th. Notably, the Mario film remains popular even in its second week. The latest Detective Conan film manages to keep fans engaged.
The film, adapted from Yūki Kamatani's manga of the same name, is a romantic comedy about a high school girl and her cold-looking classmate, Yamaguchi. The manga was serialized in Bessatsu Margaret from 2020 to 2023 and completed in 5 volumes. Due to its popularity, the live-action adaptation was greenlit and filming completed in 2025.
Although 6th place may seem like a modest start, in a period where multiple major productions compete in the Japanese box office, this result shows continued support from manga fans. In the coming weeks, the film may climb higher through word of mouth.
