What is the advantage of living in Japan?? Living in your own country is always the best because its where you were born , and you are what you are from living in your country . Theere are no advantages, unless you are talking about the quality of life as compared to other countries,and your country is better in that score .Whatever ,I suggest you travel more or , better, live in foreign lands to find out what your country can offer or not as compared to others . The bottom line is that your root cannot be severed except for some overwhelming reasons . I had done that , and I am now contented )
