What is My Future Job?

Yeah Kansas has hot temperature...now I see! I have been dealing with it barely.
Anyway, these days I have been wondering about what job to get after going back to Japan. Though I do not have any specific ideas, I think I want to use English in my job. It is my current idea. There are multiple international companies in Japan, so I will find my ideal job, but it depends on my effort.
In Japan, once we start to work for a company, we become very busy and do not have enough time to enjoy our life. The point is, we tend to work too much. On the other hand, Americans enjoy thier life while working and look very young for their age. I envy them at that point. Since I am going to live in Japan, I have to follow the Japanese way, but I will try to enjoy both my work and life!
