In Japan, train cars are usually quiet, and many passengers travel in a calm environment. This comes from social rules, daily habits, and train design. Therefore, silence in trains is not a special rule, but a shared understanding in public space.
Quiet behavior as a public-space manner

People think of trains as a place for movement, not for entertainment. Therefore, passengers try to avoid loud voices and noise. Many commuters and students use trains every day, and a quiet space helps them travel comfortably.
Rules against phone calls and speaker audio
Most railway companies ask passengers to avoid phone calls inside the car. People also avoid using speakers for music or videos, and they use headphones instead. Signs and announcements repeat these rules, and passengers follow them as a normal habit.
The same manners apply on the Shinkansen

The same quiet manner also applies on the Shinkansen. However, when someone must talk on the phone or have a longer conversation, they move to the deck area between cars and speak there.
Daily commuting increases the need for silence
Japanese trains are mainly used for commuting and school travel, not only for sightseeing. As a result, many passengers prefer a calm environment where they can rest, read, or think quietly.
Train design and track maintenance reduce noise
Train cars use vibration-control parts, and rail tracks receive careful maintenance. Therefore, running noise is lower, and the inside of the car becomes quieter as a result.
