Worth noting:

In February, was consistently colder in my apartment than outside. My refrigerator was often warmer than my bathroom. Now that it's August, it is consistently hotter in my apartment than it is outside. Given that it is around 33 C here (that's like 91 Fahrenheit) with consistent 75% humidity, I'm none too comfortable wearing a suit and tie every day.

Even though Japan is years ahead of the rest of the world in personal technology (the cell phones here are just incredible), there is a strange reluctance to adopt something as radical as a central heating or cooling system in most buildings and homes. Perhaps it's a plot by the companies that sell fans, small air conditioners and space heaters.
