A seven-year-old boy was left on Mount Fuji after his father and brother pushed ahead.
The child remained behind on a slope while the rest of the family pushed to the end.
Emergency search teams began operations early on a Saturday after the group did not come back.
Rescuers spotted the boy 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 organized the outing together, the father proceeded with the brother.
The search was triggered after the father and brother failed to reappear.
Medical staff are currently assessing the boy to ensure he is safe and well.
