Suruga Bank and the soon-to-be created Japan Post Bank, which will be the world’s largest bank by deposits, are expected to unveil an alliance in mortgages that will give the latter an entry into Japan’s massive home loans market.

Suruga Bank, a regional lender, said it had agreed to a tie-up with Japan Post Bank through which the latter will sell Suruga’s mortgages. Japan Post Bank was on Wednesday not available to comment.
