Justin Bieber is headed to Japan, despite reports that the pop star had canceled tour dates due to radiation fears.

According to OK! Magazine, Bieber's tour crew was reportedly wary about traveling to Japan after the recent earthquake and tsunami sparked radiation concerns.

However, Bieber vowed not to let his adoring fans down and took to Twitter on Sunday to confirm the final shows of the Asian part of his 'My World' tour.

"5 shows left of this leg of the #myworldtour! Manila, Hong Kong, Taipei, Osaka and Tokyo! Like I said...we are going to JAPAN! #supportjapan," he tweeted.

According to TMZ, Bieber's tour manager Scooter Braun told the concert crew to "Man the f**k up and do the right thing by these kids" when several members refused to travel to disaster-ridden country.
