A 7-year-old boy was found dehydrated and hungry but otherwise healthy early Friday morning, six days after he went missing on a mountain in Hokkaido.

Yamato Tanooka was discovered by Self-Defense Forces personnel at an exercise area in the town of Shikabe, Hokkaido, 5 kilometers from where he was last seen.

The boy was found squeezed into a pile of mattresses in a Quonset-type hut that troops on a training exercise entered because it was raining.
