J-Alert is often disliked by the Japanese people because it has repeated false alarms and its warning sound is quite shocking. North Korea has fired missiles that passed over Japan’s airspace several times, but while some people get furious when they hear the news, they go back to their normal lives as if nothing happened after a few hours. Besides, where are we supposed to evacuate when they tell us to? Under the desk? In the river? On a hill? Some of the Tokyo Metro stations in the city center function as shelters because they are deep underground, but most people can’t do anything about it.
