A local unit of Britain’s Royal & Sun Alliance Insurance Group PLC said Thursday it is pulling out of Japan’s auto insurance business. The London Assuarance said it plans to shift its focus to casualty insurance following a review of its performance in Japan.

The company, which sold auto insurance policies directly under the RoyalDirect brand, had some 17,000 policies at the end of August.

It said it will stop renewing outstanding contracts in December and introduce customers willing to renew their contracts to American Home Assuarance Co., a unit of American International Group Inc.
