About efficiency this is the number one thing I struggle to accept. An example: I am taking my license driver for bikes. What would be less efficient than a way to reserve your place for a lesson without reserving for it? This is called kyanseru-machi yoyaku キャンセル待ち予約, takes your time for nothing, 90% of the time you come back after wasting 1 hour. Number two I have heard from tourists, the trains right at time. I can't count how many times the train I took every morning was late during rainy days. So efficiency and punctuality of trains I would say no, however for the rest strongly agree, art, cars, buildings built for earthquakes, freedom in many ways, seasons, variety of natural places from tropical islands to snowy places, etc. So many things.
