Yamato was discharged from the hospital Tuesday. He smiled and waved at gathered reporters and carried an oversized paper baseball with well wishes on it.
"I'm alright," he said.
Yamato's father, 44-year-old Takayuki Tanooka, said in an emotional interview Monday with Japan's TBS television network that his son said he forgave him.
"I said to him, 'Dad made you go through such a hard time. I am sorry,'" Takayuki Tanooka said. "And then my son said, 'You are a good dad. I forgive you.'"
