In Japan, there is a culture of silence on the train that should be respected. Talking loudly or engaging in any type of disruptive behavior while riding the train is considered rude and should be avoided at all costs. To respect others while riding the train, it's important to keep conversations brief, avoid using phones (or use headphones if necessary), refrain from eating/drinking/spreading out belongings across multiple seats, offer seats if needed etc. Following these simple rules will help ensure that everyone enjoys their ride without feeling disturbed by loud conversations or other disruptive behaviors.
