16. Tokyo, Japan
Japan is a wealthy country, being among the top largest economies in the world. But it seems that wealth and prosperity of the country do not minimize the suicidal trend in some countries. We have mentioned Aokigahara forest as one of the favorite spots for suicides in Japan, but in the city of Tokyo, one such place is the Shin-Koiwa train station. For that reason, there were numerous barriers put on platforms in order to prevent people from committing suicides as well as calming pictures and suicide hotline phone numbers.
