This map of Tokyo's train system has been my constant companion since the year I arrived in Japan. It has taken me to awkward dates, successful job interviews, delicious Indian food, obscure museums and disastrous jam sessions. It has outlived wallets and pants that once contained it. Entire subway networks have changed their names since its publication. Stations once clearly visible have vanished into taped-up creases like fabulous ancient civilizations sinking beneath the waves.

I have come to know the face of my shrunken, slowly withering sage better than I know the actual geography of the area it covers, but I have only just begun to understand its true lesson: humility in the face of a higher power. Nevertheless, the time has come for us to part. Farewell, pocket-sized OIOI railway map.
