Justin Bieber hands Japan gig profits to tsunami relief

Justin Bieber has vowed to donate a share of profits from a Japan concert to the country's tsunami relief efforts after he was inspired by the generosity of rockers Maroon 5.

The Baby singer is currently on a tour of the Far Eastern country, which was hit by a devastating earthquake and tidal wave in March (11).

Hours ahead of his show in the city of Osaka on Tuesday (17May11), he spotted a post on Twitter.com from the Makes Me Wonder hitmakers pledging to hand concert takings to the Japanese Red Cross - and the teen star has followed suit.

He re-posted the message from the band to his own fans before tweeting the group and its frontman Adam Levine to announce, "Sounds like a good idea... I'm in. Gonna donate a portion of my show to Japanese Red Cross too."
