Disaster Prevention Speaker
There are 20 disaster prevention speakers (including the tsunami warning transmission system) installed in Isogo Ward. Please understand that voice may be difficult to hear depending on the surrounding environment and weather condition. When we give information to citizens, we use various means on a daily basis. In particular, in the event of an emergency, we will use a variety of means, including disaster prevention speakers, TVs, smartphones, and disaster prevention information e-mails, assuming that citizens are in various environments (indoor and outdoor, high and ground floors, quiet and lively places, etc.).

About disaster prevention speaker and tsunami warning transmission system
The tsunami warning transmission system was installed around the coast as tsunami countermeasure in 2013 after Great East Japan Earthquake. Since then, as an expansion of information transmission means, "disaster prevention speakers" have been installed inland areas.
Although there are some differences in power supply and function between disaster prevention speakers and tsunami warning transmission systems, the basic structure and operation are similar. The broadcast content of the speakers installed in Isogo Ward will be the same.
At present, the tsunami warning transmission system is organized and operated as a disaster prevention speaker.
