News Site
Nikkei
The first thing I check is the Nihon Keizai Shimbun. If you become a member of the Nikkei Electronic Edition, you will have access to a large amount of information. I think that the economic information is just as substantial.

NHK
Next is NHK, which is a must watch in times of disaster. NHK is the best for breaking news. Newspapers also provide good coverage, but my impression is that NHK is the most reliable because it is free from bias and has the largest number of reporters.

You can also find weather information here.

Yahoo! Weather/Disasters
For weather information, I basically look at YAHOO JAPAN. If you use the application on your smartphone, you can see the rain cloud radar, which is useful for countermeasures against guerrilla downpours.

Recently, it also delivers “electricity supply-demand crunch” situation in conjunction with electricity forecast.
Weather News
WeatherNews is a major weather information provider. I have the impression of aggressive weather forecasting.
