Explosive Spreading of Radio Stations in Japan 3

In 1950s, lower frequencies such as VHF band in public sectors were mainly used.

In 1985, telecommunication business was opened to private sectors. In 1990s, mobile

telecommunication has explosively disseminated and evolved.

In 2018, the subscription of mobile phone, PHS and BWA exceeded 170 million. The

number exceeded the population.
