A seven-year-old boy was left on Mount Fuji after his father and brother pushed ahead.
The child waited on a slope while the rest of the family continued to the end.
Emergency search teams were deployed early on a Saturday after the group failed to return.
Rescuers located the child a short distance from the top, and he was quickly taken to a hospital.
The incident happened on August 22, 2026.
Although the family had arranged the trip together, the father went ahead with the brother.
The search was triggered after the father and brother overran their schedule.
Medical staff are currently evaluating his condition to ensure he remains in good health.
