The Japanese society is divided over the customary practice of "two-line riding" on escalators. This etiquette of standing to one side to leave space for those in hurry to walk up or down has raised safety concerns since escalators are not designed for movement while riding. Many companies, stations, and municipalities are gradually joining the campaign against this habit due to the increasing number of accidents, despite resistance from those who value efficiency over safety.

In Japan, where orderliness is highly valued, standing aside on escalators is a deeply ingrained habit, especially during busy commute hours. However, this practice has its ramifications in terms of safety, with escalator-related accidents on the rise. This escalating debate reflects Japan's struggle between tradition and modern safety concerns.

Unlike Japan, in places like the US or EU, escalator etiquette varies. While cities like London also follow the "stand on the right" rule, it's not a universal norm. The safety issue remains, but without a deep-seated societal habit, it doesn't spark as much debate as it does in Japan.
