I can see that... I never saw in Japan unless I was on vacation... something to do with tall buildings, cloudy skies, and working until the sun was down. I never saw a sunrise either unless it was between the buildings and I was stumbling home.
Now I'm back in Canada and I see sunrises and sunsets all the time... and I have a healthy tan (not what many associate with us). So glad to be rid of the Eikaiwa flourescent skin colouring.
