The 17-year-old singer wanted to perform a concert in the tsunami-ravaged area, but he wasn't able to. So, the embassy set up a meet-and-greet with the young victims.
"Things will get better. There's only good times to come from this. So again, my prayers go out to all the families and everybody," said Bieber.
Bieber had two concerts scheduled in Japan this week. He has also contributed to a charity album for the disaster victims along with fellow artists Lady Gaga and Bob Dylan.
