The facts
The earthquake struck at 1:04 a.m. local time on 8 November in western Shizuoka Prefecture at magnitude 5.7; Chita in Aichi Prefecture recorded the maximum JMA seismic intensity of 5-plus. There was no tsunami warning. [1][2][4]
Nagoya TV reported at least 25 injuries in Aichi, including two serious, citing fire departments. Yomiuri had earlier reported at least 24 in Aichi; AP separately cited local-media reports of at least 22 across the affected area. These time- and area-specific counts are not added. [1][2][3]
Hamamatsu City’s 7 a.m. report listed one moderately injured woman in its jurisdiction and no building or water-supply damage at that time. [5]
JR Central said normal-speed Shinkansen service resumed at 8:57 a.m. after safety checks; Nagoya TV reported 29 delayed trains, a maximum delay of 52 minutes and about 17,000 passengers affected. Meitetsu reported all lines resumed by 9:15 a.m. [7][8]
The Japan Meteorological Agency warned residents in the strongly shaken areas to watch for further quakes for about a week, especially over the next two to three days; it reported no apparent change to the Nankai Trough plate. [1][4]
Aichi Prefecture and the Nagoya Local Meteorological Office temporarily lowered landslide-warning thresholds for Chita because the quake may have weakened the ground. [6]
FDMA’s preliminary report for 10:00 JST on 9 November lists 22 injured (one serious and 21 minor), two partially damaged homes and no deaths. [10]
Relevant context
Hamamatsu City reported temporary road closures after a slope collapse and falling rocks; reopening status for the route closed at 7 a.m. was not provided in the opened municipal report. [5]
Still unconfirmed
- A consolidated final injury and damage total for all affected prefectures; FDMA’s latest preliminary count differs from earlier local reports that used narrower or earlier bases.
- The subsequent conditions of all injured people and the full extent of damage outside Hamamatsu.
Corrections & updates
Correction and update, 9 November: the headline and casualty summary now use FDMA’s 10:00 JST preliminary report of 22 injured (one serious, 21 minor) and two partly damaged homes, with no deaths listed. Earlier reports of 25 injured in Aichi alone remain a separate count with a different time and geographic basis; the totals cannot be reconciled from available reporting.
