Apparently, the word for “heatwave” in Japanese is 猛暑日, mōshobi, or “very hot day” (yeah, no kidding!). Tokyo’s got it bad, with a record-breaking five straight days of temps above 35 Celsius, and plenty more on the way, if the JMA forecasts – usually a bit on the conservative side – are at all right. According to this August 5th story on Weather, however, even balmy Hokkaido is getting temps in the 30+ range, and in Tatebayashi, Gunma prefecture, near Tokyo, it hit 39.8 C on Wednesday. Yeesh.
Just glad I’m not in Kyoto…

It’s been terrible hasn’t it. Yesterday was a cool 34…
I know… doubled the old heat wave record of 4 straight days 35+ C… Feels a little cooler today, Monday Tokyo time, but still ridiculously humid and thus uncomfortable.
It seems a long time ago now. Today is the first time I’ve seen the sun here in Tokyo for ages.

It was tough early in summer. I yesterday though, was the first time I’d seen the sun in ages!
Back to the rain = a dreary end-of-summer in Tokyo?!?
