The Diet enacted into law Wednesday a legislative package that will turn the Postal Services Agency into a government-run corporation and allow private firms to enter the mail delivery market.

The bills cleared the House of Councilors in a plenary session with the support of the ruling Liberal Democratic Party, New Komeito and the New Conservative Party, and a number of other parties.

The House of Representatives approved the legislation July 9, and with the passage through the Upper House, the law will take effect April 1.
