If you have any concerns, feel free to contact the Kumamoto City International Foundation (Kumamoto City International Center).

I appreciate the hard work of the city officials who put this information out in English. I think, though, that we also need an automated system in English (and other languages) that runs in parallel to the Japanese e-mail warning system.
