In a bid to accelerate its restructuring, Isuzu Motor Ltd. said Thursday it has sold its headquarters building and land in Tokyo to Dai-ichi Mutual Life Insurance Co.

The automaker said it will also sell shares in its wholly owned leasing unit, Ifco Inc., to Orix Corp.

Isuzu sold the headquarters building and land for 23 billion yen to the major life insurer effective Thursday, while 16 million Ifco shares -- representing 80 percent of outstanding shares -- will be transferred to Orix for 20.6 billion yen effective today.
