I really enjoyed this upload and agree with your view. I am a Japanese expat in Canada and grew up in Japan. I can see things from Japanese and "foreign" perspectives. True that Japanese summer is really harsh. After all these years I am still scared of earthquakes, too. I guess "Tsuyu" has begun? Take care!
What I see is that many of them are not overworked, although some of them are still overworked, but now it has decreased, many are starting to go home on time. And don't get me wrong, Japanese people are now starting to like vacations a lot.
