Japan is famous for the tidy and cleanness of its cities and how polite and appropriate their citizens are. This is true, especially in Sendai but sometimes in hectic hours people looses their patients and forget all the rules and social norms. I stumbled upon some funny posters to remind the users of public transportation to obey these norms and not pester other people on board. I think this is also very relevant to Indonesian people.
