I had a hell of a time getting from Narita airport to my Airbnb in Tokyo.  I’m not sure exactly where I went wrong — I had the stops for each of my transfers written down, and it all seemed straightforward enough.  But somehow it went horribly awry, and I found myself staring at the almost comically complex criss-crossing lines of the Tokyo metro, wondering where I even was, or where I needed to go.
