The Japanese communications ministry will require Nippon Telegraph and Telephone (NTT) to open its next-generation fibre network, the Nikkei reports. The new network is set to launch in March this year. The ministry has decided that rules for fair competition on the new service do not yet exist and has drafted new guidelines. Rivals KDDI and Softbank have asked the ministry to open the network while NTT says it is being singled out by the government.
