Mt Gox said today the Tokyo District Court decided the company, which was a trading platform and storehouse for the bitcoin virtual currency, would not be able to resurrect itself under a business rehabilitation process filed for in February.
An administrator will try to sell the company's assets and many creditors, including those who had bitcoins with the exchange, are unlikely to get any money back.
After Mt Gox went offline in February, its CEO Mark Karpeles said that 850,000 bitcoins worth several hundred millions dollars were unaccounted for, blaming a weakness in the exchange's systems.
Bitcoins were created in 2009 by a mysterious figure or group known as Satoshi Nakamoto and are used for transactions across borders without third parties such as banks. They have also become an investment craze.
