The Who-is-Who Directory In The Public Safety Industry

Your guide to public safety solution providers

Japan Mayday Service Co., Ltd.

Although JMS is a private company, it was established with capital contributions from various companies throughout Japan, due to the high public nature of emergency call services.

Main shareholders are as follows;

  • All of the car manufacturers in Japan
  • Three major mobile telecommunication carriers in Japan (NTT DoCoMo, KDDI, Soft Bank)
  • Almost all of the major car navigation manufacturers in Japan
  • Major Banks, Insurance companies, etc.

JMS started the “HELPNET” service in September 2000, and has been providing it over 20 years all over Japan.

As of March 2024, JMS supports over seven million vehicles, and receives nearly eighty thousand emergency calls annually from all over Japan.

In Europe, #112 covers both Police and Ambulance, but in Japan, there are two different emergency call numbers: #110 for Police and #119 for Ambulance.

Based on this situation, Japanese government issued “Guideline for the Third-Party Service Providers on Emergency calls from Vehicle” in May 2018.

JMS is the only company that almost meets this guideline and can connect each emergency call quickly to most appropriate Police/Ambulance head office.

Only JMS can send accident/vehicle data and voice calls to 52 police and 722 ambulance head offices all over Japan through its leased line network.

At the AECS 3rd meeting held in February 2014, the Ministry of Land, Infrastructure, Transport and Tourism introduced JMS as “the PSAP in Japan”.
