In my area, The electric power will be cut off for 3 hours sometime during 6:20 to 10:00 tomorrow.
* Tokyo Electric Power Company grouped its area into 5 groups.
The cut off time will be set for each area.
It seems that the time will change every day.
My city offical announced it (speakers are out there in my city).
This information is not in the Tokyo Electric Power Company web site yet.
Oh, my area is group 2 (according to the TV news).
It WAS group 3 yesterday, but the number is changed...
TEPCO's site is not updated.
For more accurate info, please search your city's web site.
City's officials do their best job. Thanks!
