The little boy was found in a building on a Japanese military base about 2.5 miles from where his father left him last Saturday.
His parents left him by the side of a road to punish him for throwing stones at cars but he went
missing and they couldn't find him when they returned to pick him up..
His disappearance sparked a massive hunt involving over 130 police and school officials descending on Hokkaido, Japan's largest northern island.
"One of our soldiers was preparing for drills this morning and opened the door of a building on the base, and there he was," a member of Japan's Self-Defence Forces
"When he asked 'are you Yamato?' the boy said yes. Then he said he was hungry, so the soldier gave him some water, bread and riceballs."
The boy's father
Yamato was taken to hospital for a check up and apart from having a low body temperature, he is healthy and would be kept overnight as a precaution, a doctor said in a news conference.
The boy's tearful dad Takayuki Tanooka thanked rescuers for their efforts and apologised for causing trouble.
"We've reflected on what we did and it was really excessive.
"We - well, we loved him before, but I hope to give him even more attention now."
The Island is home to the deadly Ussuri brown bear , which can grow to a massive 550kg - almost 90 stone.
The boy fortunately managed to survive for nearly a week in the densely forested area, where night temperatures fell as low as 7 degrees and heavy rain had fallen, despite wearing only a t-shirt and jeans.
