When traveling on a train in Japan, observing local etiquette is crucial to avoid causing offense or disruption. First and foremost, you should never talk on your mobile phone; it is considered extremely rude. Phones should be kept on "manner mode" (silent). Additionally, avoid talking loudly with companions, as Japanese trains are generally places of quiet reflection or rest. You should also avoid eating or drinking on local commuter trains, although it is socially acceptable on long-distance trains like the Shinkansen. It is also important not to take up extra space with your luggage or by sitting across multiple seats; always keep your bags on your lap or in the overhead racks. Furthermore, do not cut in line when boarding; there are designated markings on the platform where passengers queue up in an orderly fashion. Finally, avoid applying makeup or engaging in other personal grooming, as this is often frowned upon in the shared public space of a train carriage.
