One day, they came across a peculiar sight. One of the trains on the Yamanote line, Tokyo’s central train loop connecting major urban centers, had been converted into a communal house on wheels. Like a normal house, it had a living room, kitchen, bathroom, garden, and even a theater, only it was shared by everyone. Walk to a station and there it was among the commuter trains. Someone described it as a magical house that had doors that opened to different parts of the city. Round and round, the unceasing cycle strung together disparate points in the city, providing a much-needed refuge from the swirling, chaotic coldness of the urban jungle. A home away from home.
