excerpt
The 32-page guide titled "Recovering From a Flood Disaster" was created by the Disaster Connection Japan Network, an organization comprising some 40 nonprofit and volunteer groups engaged in disaster-relief activities, based on the groups' experiences in flood-hit areas.
The manual is free but in Japanese. Matsuyama said that there is no plan yet to make an English version.
An application for the manual can be filled out on the organization's blog (blog.canpan.info/shintsuna/)
The website also offers a downloadable four-page leaflet summarizing the advice. It is available in Japanese and English.
