Tweet of the Week #141: Brace Yourself, Summer is Coming

It's getting hot in Japan so stay hydrated out there!

By 2 min read

In Japan, summer heat comes quickly after tsuyu. One day, the weather is unbearably humid, and the next, scorching heat makes you dread going outside. Daily small talk almost always starts with someone saying あついですね (“it’s hot, isn’t it”) as if stating the obvious helped. But summer in Japan is no joke. Heatstroke is a real threat.

Thus, whenever days are expected to get really hot in Japan and the risk of heatstroke rises, the Japan Meteorological Agency issues a 熱中症ねっちゅうしょう警戒けいかいアラート (heatstroke alert). Some cities even broadcast a warning announcement over a speaker system (防災ぼうさい無線むせん) in the morning, urging people to avoid going outside as much as possible, especially not exercising.

The warning also encourages people to turn on their A.C. However, some people would rather risk visiting the hospital (or worse) instead of spending extra money running the air conditioner. Here is NoradJapan to remind us a hospital visit could be a lot more expensive.
