I have a major concern of the ninja-obaachans that use their curare-tipped and spiked umbrellas to move people out of their way when boarding a train in order to grab a seat. In rush hour, a number of the train lines have "obaachan furii" train cars to avoid increasing the death toll, with mixed success.
