Air Conditioning -Then and Now. Cultural differences between Germany and Japan

When I first read genkidesu's post about air conditioning in Japan, it kind of got me thinking, because I had quite a different experience.  The first time I came to Japan was 2012, a year after the nuclear power plant disaster and the big earthquake. I believe they haven't started to bring the power saving changes to the classrooms then, which is why my classmates and teachers took the freedom to lower the temperature to 20 degrees celcius and it was just a matter of time until I got sick. When I got back to Japan 2016 they changed it to either 26 or 28 degrees celcius, making it quite a hot place to study in. Although people (me included) are complaining about it, I can remember not having any air conditioning inside schools in Germany sometimes having class in a room that is over 30 degrees hot, although it might have changed since I left school.

As I come from Germany, where air conditioning was almost never used (except maybe in malls, shops and some trains) it also shocked me when I found out how cold the air conditioning inside the trains in Japan were and still are. I used to bring an extra jacket just for the commuting time inside the trains but have since gotten used to the refreshing "breeze" from it and start to enjoy and even anticipate it.
