Coming from a few weeks in Malaysia and Singapore, it was interesting to see just how little and how poorly translated English is there. (They speak Japanese and not English, but lets be honest about it being the lingua franca)
It was VERY DIFFICULT to figure out how their train colors worked, how Orange gets to Blue (it's a connect, but a couple blocks away). That Ginza station (iirc, might be wrong) has at least two names.
Also, that none of the machines take cards! We were 11 yen short - about $0.10 for a ticket to the airport, and while the very nice workers were happy to explain where a few blocks away the ATM was, it would have been great if someone just threw a coin at us to get us to go away, different culture, I suppose had I asked someone would have given it to us, but I feel like in the USA it would have just been offered.
Japan was a lot like NYC, the subway there is also more confusing than places like DC or Taipei.
