Although Isawa was smart, he had a bad grade in a class of songs. The principal of Bridgewater said, "You came from the East so it is impossible. Culture is also different. So I exempt you from fulfilling the songs' discipline," but Isawa insisted that he would have to complete all the subjects because he obtained a scholarship from the Japanese government. Therefore, while he studied at the normal school, he was apprenticed to Mason, a leading figure in elementary education, (Luther Whiting Mason, 1818-1896: Mason was invited by the Government at Meiji Period, and stayed in Japan from 1880 to 1882. He taught Western music at the Music Study Committee of Education), and studied music very hard. The Music Study Committee of Education was first established within the Ministry of Education in 1879 by a proposition of Isawa and others. This is the beginning of Tokyo Music School.
