Rules of Public Transport
In order to ride pleasantly on public trains and buses in Japan, there are some unique tacit understandings in Japan. These are not clear rules, but keep them in mind so that you will be able to spend more enjoyable time in Japan.
About phone calls
First of all, as a major difference from the common sense of many countries, telephone calls in train and bus seats are basically prohibited. Therefore, when a cell phone rings while you are on board, many people tell the caller that they are currently on the move and to call back later. Since one can communicate by cell phone while traveling in Tokyo subway etc., many people respond with SMS etc., rather than responding to incoming calls. However, in the case of long distance travel such as Shinkansen, calls are permitted in the area called the "deck" between cars.
About eating and drinking in the train
Even with regard to eating and drinking in train cars, the surrounding people are somewhat stricter than in Western countries and other foreign countries, and there is no problem in drinking beverages from PET bottles, but people rarely eat. It may be acceptable if the interior of the car is not crowded, but beware of particularly smelling food. However, if there are assigned seats and tables installed in long-distance trains such as the Shinkansen, eating and drinking is generally accepted.
About the seat
Many seats in the car are covered with cloth, so standing up on one’s shoes, placing feet on multiple seats, etc. are regarded as violations of manners. In addition, there are "priority seats" at the end of the vehicle, as in many countries other than Japan. In addition to giving up seats to elderly people and handicapped people, it is also common manners to turn off mobile phones when standing around them.
