Nearly six years ago I was fortunate to travel to Japan for the second time, which is a great place for railways generally. International travel is probably off the agenda for most people for a fair while, and when it returns it will almost certainly be a massive hassle just to get into another country. So, fortunate I was!
The Japanese love their trains, past and present. And their present is our future, if we are smart about it. Most people rightly associate Japanese railways with the massive Tokyo suburban network - 158 lines, 4,715 kilometres of track, 2,210 stations and about 40 million rides taken daily (according to Wikipedia). Here are a couple of fairly boring shots around Shinjuku to make the point.
Getting into the rural parts of Japan uncovers a better style of station building, such as this one at Myonshita (take care pronouncing that one).
But mainly, it is system where architectural merit is subsumed by functionality, which is fair enough given the transport task the system faces each day.
