Tokyo-based German photographer Michael Wolf spent years documenting the world’s busiest travel system, capturing a claustrophobic nightmare endured by millions travelling across Japan’s capital Tokyo.

Michael first took notice of the incredibly crowded Tokyo’s subways back in 1995, after the infamous sarin gas attacks on the city’s subway system. He then spent years going into the subway with his camera to capture people stuck in this claustrophobic nightmare of a commute.
