TOKYO -- The Japanese government will encourage businesses to enter the fray in 5G high-speed wireless service, seeking to bring transparency to how spectrum is awarded and adopt what will likely look close to competitive bidding.
The three telecommunications giants of NTT Docomo, SoftBank Group and KDDI are gearing up to launch nationwide fifth-generation service by the 2020 Tokyo Olympics but could face challenges from new players. A more crowded market could push down charges in Japan, which top those in many other countries.
