Tokyo Telemessage, the only telecommunications company still operating the service, said it would terminate its pager offerings in September 2019 due to lack of demand.
The company said the number of users has fallen to below 1,500, despite the fact that it stopped producing the actual devices 20 years ago.
Pagers were popular in Japan and the rest of the world in the 1990s, before cell phones became widely available to the public. Tokyo Telemessage said its subscriber base peaked in 1996 at 1.2 million.
For those too young to have ever used one, pagers are a personal radio device that is used to receive messages sent via a switchboard. When the pager beeps or buzzes the owner usually needs to find a phone to return the message.
This year new government figures showed the number of children fell in Japan for the 37th year in a row.
Japan may have a reputation as a high-tech mecca famous for electronic toilets and robots but certain seemingly outdated technology pieces of technology are popular, including fax machines.
