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 pushed to the end.
Emergency search teams were deployed early on a Saturday after the group did not come back.
Rescuers spotted the boy a short distance from the top, and he was transported to a hospital.
The incident happened on August 22, 2026.
Although the family had arranged the trip together, the father continued with the brother.
The search was triggered after the father and brother did not arrive.
Medical staff are currently evaluating his condition to ensure he suffered no severe injuries.
