Today, July 25 is Memorial Day for Japan weather. Yamagata prefecture which is in northern Japan and located next to my hometown had highest temperature 73 years ago on that day.
Yamagata Local Meteorological Observatories recorded 40.8 degree around 3:00 pm. This record is an official, highest temperature in Japan that has not been broken now. Yamagata newspaper at that time told as “the asphalt of the streets were about to melt and horses seemed to cause cardiac paralysis because of the heat.”
Japanese shaved ice society decided July 25th as "Day of the shaved ice" It is commemorating the highest temperature in Yamagata.
By the way, the lowest temperature in Japan was recorded in Hokkaido 94 years ago. It was -41 degree on January 15th.
I have experienced -40 degree world at ice pavilion in Hokkaido. I honestly couldn’t enter the place because of cool air, and I even couldn’t breathe at all. It is good place to cool down your body in summer.
