A significant incident occurred at Saitama Sakae High School in which a student lost their life when a vehicle, driven without permission, overturned on the school grounds. The accident happened on November 16, 2024, and was part of a disturbing pattern where unauthorized joyrides had reportedly been taking place among students for about two years. An investigation report from the school revealed that no staff acknowledged being aware of these activities, raising serious concerns from the victim's family regarding the school's responsibilities and oversight.

The report detailed that multiple students had been escaping from the school's dormitory to engage in unauthorized driving, presenting it as a normalized behavior among students. Remarkably, not a single faculty member claimed to have knowledge of these unauthorized rides, including those responsible for managing the school vehicles. This lack of oversight is alarming given that the keys to the vehicle in question had been improperly stored in the car itself, leading to concerns about the school's organizational management and security protocols.

Moreover, the report criticized the lax security measures allowing students to exit the dormitory unrestricted, even after curfews. The family of the deceased student stressed that the school had not fulfilled its duty to provide clear explanations about the incident. This case underscores critical issues surrounding student safety and institutional accountability, highlighting a concerning gap in communication and preventative measures within the school's administration.
