These are links to search TEPCO’s website using a Google Search. This seems to result in better results than using TEPCO’s website search.
Searches for the English TEPCO site are first with automatic searches of the Japanese site later on the page. The Japanese site search works best if you use Google Chrome and the Google Translate extension. This allows on-the-fly translation. The results will not be in date order so you may need to dig through the results to find things older or newer that you may be looking for.
If you need to narrow down your search by a certain time frame once you get the search results there is an option for “search tools” towards the top of the Google Results Page. Select “search tools” and from that menu, on the far left you will see “any time”. Select “any time” and this will give you a pull-down menu where you can select date ranges like “past 24 hours”. The last option is “Custom Range”. Custom Range allows you to put a date range into only show results from those dates.
Advanced searches with more inputs such as date range, can be done with Google Advanced Search.
