Japan has a strong economy.This could be seen as a pull factor for other neighboring countries.Japanese citizens are also payed quite well,with the highest earning occupation being airline pilot,who makes 17,121,000 yen ($143,000-134,000). This is seen more in urban areas of Japan.
Japan has a very long life expectancy; the average life expectancy was 83.84 years.People believe that the work done in the rural side fills its people with purpose,which leads to them living longer (it's a matter of psychology). And,with the recent population explosion and the increasing population density, we will see more of this.Relating to life,Japan's infant mortality rate is 2 deaths per 1,000 live births.
Japan is politically stable.Japan has an economic freedom score of 72.7 and it keeps increasing.The country is ruled by Akihito,the Emperor of Japan (left) and Shinzo Abe,the Prime Minister of Japan (right).. In terms with the Japanese ecumene,Japan's island of Honshu is full of ports and stuff of the sort.
