My train line is one of the busiest in Tokyo. Yesterday's ride was absolutely miserable. Had my arm folded against my chest, and people pressed up so close that it folded my elbow past its range of motion, like having a joint-lock-submission put on me.
Today, it was raining, and there'd been a "human-related accident" on the train lines, so everything was running late. The first delayed train arrived and it looked worse than yesterday's so I skipped it.
When the next train came, it was nearly as crowded, but I had to get to work, so I got on that one. People are not moving out of the way to help people disembark. Just really feeling like Tokyo is forgetting its fucking manners this week.
