It was revealed on April 2 that the Japanese government formulated a draft outline of the general strategic plan for the “6G” network as a next-generation communications standard to succeed the “5G” network. The new network standard is expected to be in use in the 2030s. The plan will accelerate development of the new network and prepare an environment to facilitate telework and provision of remote medical care. A joint public-private research and development hub will be newly established. Together with drastic deregulation and financing support, the plan aims at laying the groundwork for the principal technologies in 5 years. The timeline to make improvements on the 5G network, whose services started in spring 2020, will be moved up.


A Ministry of Internal Affairs and Communications meeting of experts drafted the plan, which will be reported at the April 3 “Mirai Toshi (future investment)” meeting (chairman: Prime Minister Shinzo Abe).


The 6G network is the sixth-generation communication network standard. In the draft plan, the 6G network is positioned as a national strategy. The plan aims to have public and private sectors collaborate in the development and implementation of the 6G network, as well as to move up making improvements to the 5G network. A hub to enable industry, government, and academia to bring together technologies, called the “Beyond 5G research and development platform,” will be launched to realize these goals. The government plans to amend the Radio Law to create an environment that will facilitate testing and support development with tax incentives.


At the moment, the 6G standard is not fixed. The plan assumes the transmission rate is set to be one thousand times faster, and information transmittance delay to be one-hundredths of the current 4G network. The 6G network will utilize satellites so that it will be accessible from underwater or from midair, and even in outer space.


The draft plan calls to accelerate the propagation of the 5G network. The standards for setting up base stations will be reviewed in the summer of 2020 so that 4G base stations can be converted to 5G stations. The draft plan increases the number of 5G base stations established by March 2024 to 210,000, which is triple the 70,000 stations in the current schedule. The draft plan aims to create 44 trillion yen of added value by fiscal 2030 with the acceleration of 5G network improvements.
