It was when he became a sophomore in university that the relationship between English and Satoshi changed. He decided to apply for the exchange program of the university because he wanted to become independent from his parents as he is an only child and he felt he depended on his parents too much. Another reason was that he had admired foreign countries since childhood. Even though studying English was not the reason for his decision, he had to pass the TOEFL to be chosen as an exchange student. He bought TOEFL preparation books and mainly studied the grammar part for half a year, and he successfully achieved the score 500 on TOEFL. He acknowledges that “I’m a kind of person who can concentrate on one thing when I decide to do so.”
