Tokyo power outage maps

Due to extreme impacts of earthquake and tsunami on the Japanese electrical energy grid, power companies in Japan are putting into place scheduled outages to reduce their energy load.

The TEPCO web site is under extreme load, and is throwing error messages on the main page: "An error occurred while processing your request. Reference #97.1c1fac41.1300025768.58c0d00". Deeper links appear to be less affected. Here is from a TEPCO news release of 3/13; this is data that could be mapped.

Schedule for Japan's Rolling Blackout. This unattributed PDF is all in Japanese, which I don't read; it appears to be a scan of a facsimile, and has all external indications of being genuine. The map below is excerpted from that original, and is from the TEPCO power service area. There is more excellent coverage (in Japanese) on Gigazine: 2011/03/13 Rolling Blackouts.
