Japanese schools do practice student-led cleaning (called Osoji), a tradition that involves students cleaning classrooms and shared spaces. The practice is common in many Japanese schools, though not universal across all schools or all students. The timing varies — cleaning often happens after lunch or at the end of the school day, rather than following a single standardized schedule. This practice is embedded in Japanese education culture as a way to teach responsibility and shared community care. It connects to the broader cultural pattern of collective maintenance — the same philosophy that leads Japanese fans to clean stadiums after sports events, which has gone viral on social media.
