Justin Bieber is putting his money where his tweets are -- he's going to Japan.
As TMZ first reported, some of Bieber's crew refused to go on the tour stops in Japan because of post-tsunami cancer concerns. But sources close to Bieber told us earlier this week ... he was going no matter what.
Bieber tweeted his plans today ... confirming the tour stops in Japan will go on as planned.
Never say never ... go to Japan.
