Never talk on your phone while on the train, unless using the designated phone area of the shinkansen. Silence and use headphones so that your media cannot be heard by others. Finally, turn your phone off if sitting near the priority seating area.

Yes, maintaining a quiet atmosphere is a fundamental part of Shinkansen etiquette and Japanese train culture in general. While it is not a "silent" car, passengers are expected to speak in low, hushed tones so as not to disturb others. Talking on a mobile phone is strictly prohibited in the seating areas; if you must make or receive a call, you should move to the "decks" or vestibules between the carriages where it won't be heard by fellow travelers. Other "quiet" rules include setting your phone to "manner mode" (silent) and keeping your headphone volume low enough that the sound doesn't leak out. These social norms are based on the concept of omoiyari (consideration for others), ensuring that the high-speed journey is a peaceful experience for commuters and tourists alike. Breaking these rules is considered quite rude and may result in subtle but clear disapproval from fellow passengers or a polite reminder from the train conductor.
