When the Postal Services Agency is reborn Tuesday as Japan Post, the public corporation is expected to increase its operational efficiency and better serve its customers.

Japan Post will take over mail delivery, postal savings and "kampo," the postal life insurance program, from the agency, employing some 280,000 workers and operating about 24,700 post offices nationwide.

Allowed greater freedom to plan its business strategy, including budget size and the number of employees, Japan Post is expected to turn a profit in each of these three components by cutting costs and offering attractive services, marking a departure from its inefficient, government-operated predecessor.
