Road map of Natori emergency FM radio 'Natoraji'

This knowledge note addresses the transition between emergency FM to community FM radios in Japan following the devastation brought by the March 11, 2011 Great East Japan Earthquake, which destroyed the regional disaster prevention emergency communication. It explains that temporary emergency FM stations broadcasted detailed local information so that tsunami advisory and warning could reach the residents, but that they had to become community FM in order to continue broadcast after their operational expiration date.

The document analyzes the transition process of Natori Emergency FM Radio (or “Natoraji”) from being an emergency radio to a longer-term community radio, in which its online (broadcasting) and offline (community activities) roles were found important to sustainably promote community disaster risk reduction awareness raising.
