When Lehman filed for bankruptcy protection in September, so did its Lehman Brothers Japan Inc. unit, which filed in Tokyo.

According to the Journal, two of Lehman Brothers Japan's real-estate loan units, Lehman Brothers Commercial Mortgage KK and Sunrise Finance Co., had liabilities totaling 748.4 billion yen ($8.44 billion).

While Japan's Nomura Holdings Inc <8604.T> bought Lehman's operations in Asia, Europe and the Middle East, it did not take any debt held by the failed U.S. bank, the Journal said.

The Journal said first-round bids for the assets were placed on Tuesday. Companies showing interest include funds at Lone Star, Cerberus Capital Management LP , Goldman Sachs Group Inc's Goldman Sachs Japan Co., Blackstone Group LP and a Nomura Holdings <8604.T> unit, the people said, according to the report.

Lehman declined to comment on Saturday. Lone Star, Cerberus, Goldman Sachs, Blackstone and Nomura could not be immediately reached for comment.
