I and all Japanese people very thank for many support of world people and countries.
Kanto-region (including Tokyo, SQUARE-ENIX located) is now under electric power shortage.
This is caused many electric power plant using fossil fuel in Kanto-region was offline, or working 50% output due to damage of the earthquake. (All of nuclear power plants in east are shutdown).
Then Kanto-region was divided in 6 areas (No.0 to No.5) and No.1 to No.5 areas are suspension of electricity service by turns.
(No.0 area is central of Tokyo, and it is not the suspension area)
(SQUARE-ENIX located in No.0 area. SQUARE-ENIX can be supplied electric power 24 hours, but they turned off game servers to help Tokyo Electric Power Company (TEPC))
There are some reasons to interrupt power recovery in Kanto-region and Tokyo.
One of there, A.C. power frequency is different between east and west in Japan.
Of course, three frequency-transform institutions ware prepared, but those transform capacity is one million kWh at the most (and already fully supplying). Kanto-region needs 10 million kWh or more to prevent the cycle power suspension.
TEPC will lose 4 or more nuclear reactors, and it means Kanto-region loses 4 million kWh or more elec power source.
After a week or so, most power plants using fossil fuel will return normal output.
All of those plants located ashore, so fuel will supply by tankers.
However, 30% of elec power supplied from nuclear power plant in Japan, and all of east nuclear plant will not start operation shortly. It is clear that people living near nuclear plants oppose those starts, even if the reactors not damaged.
I have no idea when elec power supply back to normal in Kanto-region.
This is not only SQUARE-ENIX problem, but also all over Japan.
I hope when elec supply of fossil fuel power plants start, SQUARE-ENIX also starts their servers.
