Because of Sakura Science Plan, I can see that Japan has a lot of very high technology which is interested to continuous study. Moreover, cleanliness of country make Japan livable.
When I live in Japan I have to use many equipment for my research but I don't know how to use the equipment. Everyone in my lab sacrifice to teach me. Everyone is very friendly. Especially professor takes care of me nicely.
If you want to study in next degree or higher level but you don't know which country is interesting, I recommend you to add Japan in your choice. Because of many reason such as beauty of country, quality of life, technology, characteristic of people, basic knowledge of study etc.
