Japan’s extensive & generally user friendly rail system was the best way to get from ‘a’ to ‘b’. Underground, it’s a little difficult to tell which direction is which, but we found a few shops (eg: ‘cube’ subway entrance next to Juicer Bar) with which to gather our bearings.
Elevators and escalators also abound, but only if you go towards the correct exit. What are the chances of zigging instead of zagging and getting stairs every time? Probably quite remote, so I suspect some intergalactic deity is toying with our little lives…
