I've not been to Tokyo but I lived on the Gulf Coast (U.S.) for six years and it was similar. Summers were typically high 90s with humidity runnng between 90 - 98 % when it wasn't raining. I really didn't like it. It's been 100 F for the last two days and today will be another before it is projected to "cool down" tomorrow to 90 F. It is very dry here in Northern California which is a big plus in the summer. It is the hottest summer I can remember in my 35 years here although the weatherman said it was worse one year in the 1970s.
