The devastating magnitude 9.0 earthquake hit Northern part of Japan on March 11 (Japan time). While I hear lots of up-to-date information in Japanese, I find the information in other language is very limited. There are more than 2 million foreigners live in Japan, and many tourists visit Japan throughout the year.
Most of the sites listed here are in English. Some of them offer the information in other languages, too. (You’ll see a link to other language on their site.) Hope the information here help non-Japanese speakers in Japan, and non-Japanese speakers who know someone in Japan.
If you know of any useful sites and the services not listed here, please post it in the comment.
