Yahoo Japan says an online bidder has pledged a staggering $73 million for a crystal piano put up for a tsunami charity auction by a heavy metal band musician.

Yahoo Japan says it had to suspend the auction after the bidding price for the piano belonging to Yoshiki of X Japan hit 6 billion yen ($73 million) earlier this week.

Yahoo has emailed the bidder to confirm the intention to buy the piano, but said Thursday they have not yet responded. Yahoo will wait for several days before putting the piano up for auction again.

Yoshiki is among 280 artists, athletes and celebrities who joined the auction to raise money for reconstruction efforts after Japan's March 11 earthquake and tsunami left more than 27,000 people dead or missing.
