An emotional Lady Gaga pledged to use her star power to “remind the world that Japan is safe” following the March 11 earthquake, tsunami and nuclear disasters.

The performer, ranked this year’s most powerful celebrity by Forbes magazine, is in Tokyo for the charity concert MTV Video Music Aid Japan, to be held on Saturday at a convention hall in Chiba near Tokyo.

“I believe it’s time to look forward now,” a teal-haired Lady Gaga – or Lady Gaga-san as she is referred to in Japan – told reporters at a press event in Tokyo as she sipped tea on stage in front of photographers.

“It is so important that we continue to raise money. But it is also important that we remind the world that Japan is now safe and that the doors are wide open for tourists from all over the world to come in and enjoy the beautiful country.”

She said she would auction off her tea cup to raise funds for the Red Cross. The American singer has so far donated around $3 million for people in the disaster zones, including revenues from selling a wristband that her Haus of Gaga behind-the-scenes creative team produced, and personal contributions, according to local media. “I would like to use my position here today and all week-long to run around Tokyo and enjoy the beautiful city and kiss all the beautiful little monsters,” she said, referring to the name she gives to her fans.“
