So far, on this trip, the majority of Japanese people I have seen would be described as being slender. I’ve seen very few you would describe as overweight.  I had always assumed that this was due to their diet.  But watching them running around train stations I’m starting to think it’s because they are always in a hurry.  I really don’t understand what the rush could be.  This morning there must have been a train going to Tokyo station every three minutes yet people were still running to catch them.
