- Millions of Japanese use cell phones, which lead to poor etiquette initially. For example, shouting into the phone on crowded trains disturbed other passengers.
- Messages play on Japanese trains asking people to put their phones on silent, or as the Japanese call it "manner mode." Texting continues to be extremely popular in Japan because of this and a very low text rate cost.
- Japanese law prohibits driving a car or riding a bicycle while using a cell phone. Furthermore, it cautions against walking while using the phone to avoid annoying other pedestrians.
- Do not take pictures at shows and performances, as it is not allowed. When taking pictures outside of these places, use discretion and respect other people's privacy.
- Japanese cell phone etiquette requires cell phones turned off when around the elderly on public transportation or in hospitals. Doing so avoids disrupting medical equipment, for example, pacemakers, with the cell phone's electromagnetic waves.
- The same rule for hospitals applies to cell phone use on airplanes as well and for the same reasons. Ignoring the rule may cause penalization by law.
