One news outlet here is reporting temps could reach close to 100F (translated from around 40C) here in Tokyo tomorrow. Last few days have been quite brutal with temps soaring around 95 in various places around Japan. Also, quite unusual in my opinion, we have seen pop-up severe storms plague the region, with lightning killing an elderly woman near the Arakawa river the other day.
This doesn't seem to be quite normal. I spent the last 2 summers before this one here in Tokyo and, although it's quite hot, it never got near this hot, nor did we see supercells. Also NTV is reporting a record number of people have been treated for heat related illnesses this year than any time the last 2 years or so.
Is this normal? Is this a monsoon-related product, or a result of El/La Nina?
Either way, to my Japanese friends on here, 気を付けて！

Certainly does not sound normal to me, but I am not expert on Japanese meteorology. The summers have always been lovely in my experience. I hope it cools down before I arrive at NRT in a few weeks time!
I've always been a weather nut and kept a lot of notes over my life.
In 1983 we have five straight days in Yokosuka over 100, over 103 in downtown Tokyo. I think every day from July 4th to August15 was over 95. There were heat / humidity pop-up small severe thunderstorms in the Kanto several days that summer.
In 1984 we had no days over 95.
In 1985 we had two days over 100, and about 6 over 95.
In 1986 we had five days over 100 - only two consecutive, no more than 15 over 95 - but we had a lot more thunderstorms. One of the most impressive I saw was over Tokyo Bay while I was at the top of Mount Fuji in mid-August. It was 6 AM and this very visible thunderstorm formed over the Bay.
I would think that the heat/ humidity within the Tokyo Metroplex is increasing each year, because of the increased urbanization, not 'climate change'. The more and bigger buildings they build - the more heat is retained over night, and makes it hotter the next day.
Green space does not hold has much heat and helps allow the residual heat to dissipate at night.

This has happened every other summer that I've been here. Pop up t-storms have generated tornadoes in Gunma, Chiba, and Yamagata that I can recall off hand.
Three summers ago in the Nagoya area (typically one of the hottest cities on the Japanese map) there were temps over 40 in the suburbs in Gifu three consecutive days. That same summer there was an incredible run where we had four consecutive nights of Texas-sized thunderstorms.

I wouldn't hold my breath if I were you...lol
If you need someone to blame / throw a rock in the air / you'll hit someone guilty
