Lady Gaga is apparently on top of it when it comes to donating money to those affected by the March 11 Tōhoku earthquake and tsunami in Japan.

Today, it was announced that the pop star donated $1.5 million to Zynga’s fundraising initiative with Save the Children, as well as to the American Red Cross.

Gaga raised these funds via sales of her Japan Prayer Bracelets. “I’m inspired that my little monsters banded together to help those affected by the terrible tragedy,” she said in a release.

Last week, the singer also participated in a benefit album called Songs for Japan, which also features popular tunes in original, remastered, live or acoustic formats from Bob Dylan, Bruce Springsteen, Justin Bieber, Eminem, Katy Perry and more. Worldwide proceeds from album downloads will go to the Japanese Red Cross Society.

Zynga, for its part, donated more than $2.5 million in the last two weeks for Save the Children’s Japan Earthquake Tsunami Children in Emergency Fund via its social games (Café World, CityVille, FrontierVille, FarmVille, Words With Friends, Vampire Wars, YoVille and Zynga Poker). Players donated 100% of the purchase price of virtual goods to the relief effort.

What do you think of these methods of fundraising? Would you buy a bracelet — or a virtual farm — to benefit charity?
