Meanwhile, there's no apparent way to pay for a train using an American android phone (or at least I couldn't figure it out last year). One of the two apps refused to install on non-japanese phones, the other installed but refused to run. Had to pay with cash and it was a huge pain. Half the time I inexplicably had to do a fare adjustment, a hugely embarrassing moment blocking the turnstile, especially considering the culture there.
