Earlier quoted context omitted.
I think the "clockwork" reference is somewhat overrated. Local trains are often late due to wind or snow ..
Do you live in Hokkaido? Or maybe on a really local branch? I live in Tokyo, take around four trains a day on many different lines and that is just not the case here.
I'd like to think of Tokyo As the exception to Japan. Having said that, all the pointing and calling is happenening everywhere.
