Japan is a great destination. Not only are there plenty of job opportunities but Japan is one of the most intriguing, entertaining, and impressive nations in the world. I personally spent five years teaching EFL there. It was one of the best, most rewarding, and unforgettable experiences I have had overseas. I do not foresee you having any trouble getting a job. With your business savvy, a four-year degree, a TEFL Certificate, and a winning attitude, there is no need to worry. In my experience, the Japanese are extremely hospitable, patient, and help make the transition to life overseas very easy, regardless of your age. It is important to be flexible wherever you go. There are cultural differences that can be a very challenging so it is important to be aware of how you are acting, feeling, etc. in relation to where you are. For me, the hardest part of living in Japan was having to leave. I often consider returning. If you have any specific questions about Japan please feel free to email me at info[@]teflflyer.com.
