Delivery company Tokai Messenger Bb on Sunday launched limited mail delivery services, making it the first private-sector firm to take part in the state-run service since 1873.

The company, based in Nagoya, has acquired a license that only allows it to deliver mail within three hours of receiving it. It will operate in the central areas of Nagoya.

"Most of our customers are advertising agencies and design firms, but we can now also handle public documents such as tax statements," Tokai Messenger President Kenichiro Imai said.
