System error explanation
The agency's system mistakenly placed the epicenter off the Kuril Islands and overestimated the magnitude, triggering the initial warning.

The quake registered shindo 1 on Japan's seismic scale in Hokkaido with no strong shaking reported in Japan.
Investigation ongoing
The agency is investigating the cause of the system error and will provide an explanation once determined.
The bottom line
