The Japanese unit of failed cryptocurrency exchange FTX said Friday it would return its customer assets from February.

FTX Japan is developing a system with which customers can withdraw assets via the website of Liquid Japan, a crypto exchange it bought in February.

¡°We deeply apologise for the big trouble caused by the prolonged suspension of services for the withdrawal of legal currency as well as crypto assets,¡± FTX Japan said in a statement.

FTX filed for U.S. bankruptcy protection in November and its founder Sam Bankman-Fried resigned as chief executive after the biggest blowup in the crypto industry drew calls for tighter regulation.
