I'm perplexed because the top temperature noted in the Japan Today article is 35 degrees, which is equivalent to 95 Fahrenheit.
I live in the desert and our summer temperatures can reach 120 Fahrenheit so heat stroke at 95 doesn't seem highly likely for such large numbers of people unless elderly people are inside hot apartments without air conditioning.
When I posted on this subject on July 24 someone left an interesting comment that I am going to repost here:
I'm a resident of Tokyo, and can assure you that the meme of "heat
stroke" has been pushed quite a bit in the last few months. One big
article was about how heat stroke was four times as bad this year as two
years ago. Climate change, of course, so carbon indulgences owned by
Tokyo Electric are the answer.
There are also a couple of
relatively new NGOs/charities that deal with heat stroke, and they have
the money for full-page ads in major newspapers.
