from the text,we know the text is about Japan country (because in the text tell about visited Japan/pergi keluar negara, berkunjung)

from the text above,we know that In my country (Indonesian maybe) making calls on our cell phone while on the train or bus is alright, although it doesn't happen often. However, in Japan, there are strict rules forbidding the use of cell phones. We can see the signs everywhere in the public transportation, and Japanese people diligently abide by these rules.
