Nippon Express Co. adviser Shoichiro Hamanaka will be appointed chairman of Tokyo Metro Co., which will be created April 1 via the conversion of a governmental subway operator into a stock company, government sources said Tuesday.

Hamanaka, 74, has held his current post at Nippon Express since June, having previously served as president and chairman of the transportation company.

Tokyo Metro will be established through the conversion of Teito Rapid Transit Authority, 53 percent of which is owned by the central government and the remainder by the Tokyo Metropolitan Government.

The two governments will hold the same ratio of equity in Tokyo Metro once it is established.
