It turned out that the J-Alert, the national instant warning system, was the slowest ever to be issued over the launch of a ballistic missile by North Korea on the 4th. The government plans to consider improvement measures for prompt dissemination.
When North Korea launched a ballistic missile on the 4th, the government sent evacuation information to the relevant areas with J alert and called for vigilance.
Of these, information was sent to Aomori Prefecture at 7:29 am, regarding seven minutes following the missile was launched, which almost coincided with the time when the missile was estimated to have passed over the vicinity of the prefecture. There are opinions calling for verification, such as “Even if the J-alert sounds following passing, it’s too late.”
The first J-Alert information on missiles was released in 2012, and at that time it took regarding 6 minutes from launch, but due to the progress of operational proficiency, the previous time in 2017 was regarding half, regarding 3 shortened to minutes.
However, this time, the information transmission to Aomori Prefecture was regarding 7 minutes following the launch, the slowest so far.
There is a view within the government that in 2019, the target areas for information dissemination were changed from regional blocks to prefectures in detail, so analysis has become more time-consuming.
The government has decided to consider improvement measures for prompt transmission, saying that even a slight delay cannot be overlooked.
