Japan Post Corp. is considering listing in fiscal 2011 two of the four units that will be created during the organization's privatization, starting next year, sources said Wednesday.

Japan Post, which will hold shares in the privatized postal savings bank and postal insurance company, intends to say when it will list the two units when it completes its business plan at the end of July.

The government is planning that the four units, including one for mail delivery services and another to manage over-the-counter services, will be completely privatized by the end of September 2017.

Japan Post would reduce its stakes in the two units through initial public offerings for them in fiscal 2011, to allow them operate on a broader basis before becoming completely private, the sources said.

Japan Post also is considering having the postal savings bank offer credit-card services. It is eyeing "third-sector" insurance services, including medical and nursing-care insurance, for the insurance unit as well as raising the maximum amount of benefits from 10 million yen.
