Rolling Blackout

Rotational electric power interruptions are planned by Tokyo Electric Power Company (TEPCO) and Tohoku Electric Power Company (Tohoku EPCO) to prevent sudden massive blackouts.
The areas managed by TEPCO and Tohoku EPCO are divided into several groups. For each group, there will be a 3-hour maximum of electric power interruption (intentional blackout) within the scheduled hours.

TEPCO's rotational blackout will take place in Tokyo, Kanagawa, Chiba, Saitama, Gunma, Tochigi, Yamanashi and Shizuoka Prefectures. Ibaraki Prefecture is excluded because of severe damage, although some areas near the border may still be included in the blackout areas. The rotational blackout started from March 14 and may last for a long time since the use of electric power is predicted to rise during the summer.

Tohoku EPCO's rotational blackout will take place in Akita, Yamagata and Niigata Prefectures as well as parts of Aomori Prefecture. Tohoku EPCO canceled all of the palnned blackouts previously announced for the low demand for electric power made it unnecessary, so from March 16, blackout has not yet occured. Nevertheless, Tohoku EPCO does not deny the possibility of future intentional blackouts.

The planned blackout will cause some changes in train&bus schedules. For more information, see TransportationStatus.

General information

  • From time to time, the website of TEPCO and Tohoku EPCO will be crowded from excessive access. Wait for a while before reloading the page.
  • The exact duration of the planned blackouts may vary depending on the demand for electricity.
  • Depending on the situation, there may be interruptions other than the scheduled ones.
  • If a certain region belongs to two (or more) groups, there might be more detailed information available at the electric power company's website, or it may be that the company doesn't know which group that region really belongs to until the blackout is actually takes place.
  • Some areas may not have blackouts during the scheduled timeslots. However, wasteful use of electricity will elongate the whole program of planned interruption.

What to prepare for blackouts

Here is general information on what to prepare for blackouts.

The following information is from:

What to do before blackouts
  • Unplug your electric appliances just in case.
  • Turn off and unplug your computers and hard drives to prevent data loss.
  • Save some water if you need it. Some buildings use electricity to pump up water. Hot water supply may be lost during blackouts if your system runs with electricity instead of gas.
  • Refrigerators can maintain its low temperature for a few hours. If you want to raise its efficiency, you can take things like ice, refrigerants or ice packs from the freezer room to a cold room.
  • Fully-charge your mobile phones.
  • Prepare a battery-powered radio.
  • Get flashlights in case for evening blackouts.
  • Public transportation may be affected by the blackouts. Contact your school or office for information when necessary.
  • Prepare your meal before the blackout if you need it. Be careful when you heat food using gas stoves since the fan for ventilation won't work during the blackouts.


The English website of TEPCO has been renewed, but there is still a time-lag for the latest information made available. Chinese and Korean websites are available as well.

Schedule for the TEPCO blackouts

The latest information the blackout is available at the official website of TEPCO.
Cautions for blackouts

TEPCO announced on April 8 that no blackouts will take place in the foreseeable future.

Grouping for the TEPCO blackouts

Current list

TEPCO areas are divided into 5 big groups, each big group is subdivided into 5 subgroups, making 25 subgroups in total. These subgroups are labeled Group 1-A, Group 2-C, etc. Some areas have been added to the blackout areas, but there are no changes to the "five big groups", if your area belonged to group 3 before, your area is likely to be in group 3. The official press release about the subdivision is available in English.

When the same address has more than 2 groups assigned on the grouping table, the address has more than one electric power substation; therefore, different areas within the address will be in different groups, according to which substation the area belongs to.
e.g. 神奈川県愛甲郡清川村煤ヶ谷 (Kanagawa-ken Aikoo-gun Kiyokawa-mura Susugaya) has group 1-E, 4-D and 5-D assigned. My house in Susugaya may be group 1-E, but my neighbor's house may be group 4-D. Once groups 1-E, 4-D and 5-D experiences planned electric power interruption, my neighbor & I will know which group our houses actually belong to.

An illustration of the sub-grouping from the TEPCO website:


TEPCO may use symbols to indicate whether interruption will occur or not.

Forecast symbols from the TEPCO website.

  • a black circle (the symbol to the left) means "blackout is scheduled"
  • a circle half white and half black (the symbol in the middle) means "there is a possibility of an intentional blackout"
  • a white circle (the symbol to the right) means "NO blackout is scheduled"

Detailed grouping tables for the 25 sub-groups (five sub-groups for five big groups) are available on the Japanese website of TEPCO.

  • いいんじゃないでしょうか>色づけ Mac OS X上のSafariで見たら東京電力資料で使われている色とずれて見えたので(他のブラウザではずれていなかったのかも。もしそうならすみません)、近づけてみました。29日のスケジュールが出たので掲載しました。 -- ymatz (2011-03-28 19:28:14)
  • 早速更新ありがとうございます(かぶるところでした)! 私はAdobe Readerで表示される色をMac OS Xのスポイトツールで選択しましたが、Safari経由だとCMS(色管理システム)が効いているのかもしれません。大体合ってればいいと思います、ちなみに私の画面(Firefox 3.6, iBook G4)では大きい変化は見られません。 -- Guang (2011-03-29 21:46:55)
