The trustees of failed theme park operator Huis Ten Bosch Co. have chosen Nomura Principal Finance Co. as the firm's rehabilitation sponsor, trustee chief Shigeaki Momoo said Wednesday.

Nomura Principal Finance, the investment arm of the Nomura Securities group, outbid three other potential buyers, including U.S. investment firm Ripplewood Holdings LLC, with its pledge to invest more than 30 billion yen.

The court-appointed trustees of Huis Ten Bosch, which operates the Huis Ten Bosch theme park in Sasebo, Nagasaki Prefecture, are expected to finalize the deal by next month, the trustees said.
