A teacup and saucer used only once by pop sensation Lady Gaga has sold for more than 6.0 million yen ($73,700) at auction.

With more than 1,300 bids, the week-long charity auction finished with a top offer of 6,011,000 yen, Yahoo! Japan confirmed.

But payment is required before the winning bid can be confirmed, it added.

The cup was used by Lady Gaga at a press conference in Tokyo three months after the massive tsunami of March last year swamped a large stretch of Japan's coastline.

Lady Gaga told reporters at the time that she would auction the cup, marked with her lipstick and bearing the Japanese message "We pray for Japan", along with her autograph.

All the money raised from the auction will be used to help young Japanese artists who want to study in the United States.

The teacup was one of a number of items being sold to raise money for those affected by Japan's worst post-war calamity, and was the second most expensive lot.

The top-priced item was a Kawai crystal piano used by Yoshiki of rock band Japan X, which went for 11,001,000 yen.
