Post#3 Transportation Etiquette

Japan has the JR line that is the most popular train company in Japan. So, I think about JR train's etiquettes. JR has two kind of rules: Written rules and Unwritten rules. 

In the case of written rules, 

1. Don't smoke. 2. Don't litter something. 3. Don't listening to loud music. etc... 

In the case of unwritten rules, 1. Give eldery people your seat. 2. Don't block the way when someone takes off from train. 3. Don't put your feet on the seat. etc...
