Mitsui Mutual Life Insurance Co. and Sumitomo Mitsui Banking Corp. said Monday they have agreed on a tieup in mortgage loans.

Under the tieup, the life insurer will introduce customers seeking mortgage loans to the bank.

Mitsui Mutual is the first Japanese life insurer to arrange mortgage loans by a bank for its customers. The Insurance Business Law was revised in June to allow life insurers to serve as agents for banks.
