55.03 NHK & J-ALERT
Why it matters
Japan’s nationwide emergency communications rely on the J-ALERT satellite system and NHK’s mandatory reception framework. 41.07 Mobile, Internet and Communications instructs residents to prepare devices for multilingual alerts and arrange NHK reception contracts shortly after moving into a permanent home.
System overview
J-ALERT
FDMA pushes missile, tsunami, volcanic, and severe weather warnings directly to municipal loudspeakers, television, radio, and compatible mobile phones within seconds of detection. Review the official FDMA briefing for supported channels and alert categories.
NHK受信料
Residents with televisions or tuners must register and pay reception fees, which fund national and local emergency broadcasting capability. Complete the paperwork via the NHK reception fee portal and monitor the NHK World live stream for English-language emergency coverage.
Carrier integration
Major carriers deliver J-ALERT and Area Mail messages through their disaster alert apps, complementing municipal LINE or push services discussed in emergency-alerts—disaster-apps.
