The Japanese railway company Nishitetsu has released a humorous video about train etiquette that features two high school girls viciously competing for an empty seat on a crowded Japanese train.
The video, called “Air Chair High School Girls” (kuuki isu joshikousei), shows two high school girls engaging in all sorts of inappropriate and sometimes just bizarre behavior, all because there's an empty seat on a crowded train and they really want to sit down. Although the video is very amusing, the intent behind the video was to show people an example of how they shoulldn't behave when riding a train.
The video is about 2 minutes long, features beatboxing and there is no spoken dialogue so it’s quite amusing even if you don’t know any Japanese. Enjoy (and yeah, as Nishitetsu says, don’t do this kind of stuff next time you’re on a train in Japan).
