I help people prepare for the TOEFL test. I teach at a prep school in Japan mostly, but I also publish a bi-monthly distance-learning material for learners who cannot come to see me at school. A Japanese native, I do not know much about the English language, but I know better about the TOEFL test than most people. It is always my pleasure to see my students off when they leave for whatever university or grad school they will be attending. When they graduate and start to contribute to society, I feel I made a decent contribution to the world. A rewarding experience.
