Foreigners' big questions for the Japanese series. This time, we thoroughly discuss differences in the way foreigners and Japanese people think about actions in public places. We look at differences between Japanese people and foreigners, such as “Why are Japanese people hammered drunk on the streets?” and “Aren't Japanese people embarrassed to read erotic books on trains?” Japanese people can’t tell the difference between sexy and erotic!? Why have differences in actions in public places emerged? We close in on cultural gaps regarding “actions in public” while mixing in opinions of the Japanese in response to foreigners' questions.
