The next nationwide J-Alert message transmission test is scheduled for November 11, 2026, at 11:00 a.m. Japan Standard Time (JST). The J-Alert transmission test is a coordinated drill intended to ensure that critical emergency warnings can be sent instantly from the national government to citizens.
The test will ensure that satellite and ground network connections are operating smoothly. It is jointly conducted by the national government and local municipal authorities.
Information Channels
When the clock strikes 11:00 a.m. on November 11, the emergency signal route will activate through the “Local Government Route”. Municipalities will use different community channels to simulate the delivery of an actual emergency alert.
Public loudspeakers used for disaster warnings are scattered across neighborhoods. On cable television, automatic text overlays will appear or audio alerts will interrupt programming. On community radio, live alert audio will interrupt regular programming. Moreover, automated text alerts will be sent to residents who have subscribed to local municipal emergency mailing lists.
After the broadcast, local emergency divisions will document any equipment malfunctions they detect. Municipalities will also release information regarding identified communication failures following the broadcast to keep the community informed about the situation as repair teams work to resolve any problems.
