Dr. Jun Imazato was a dentist in Japan and a baseball fan. This obsession with baseball dates to his days at dentistry University. In 1946, being fond of English and baseball, he would listen to the report of MLB games on shortwave FEN whenever he found time. He was not a mere listener, he went so far as to fill out a scorebook. At first he did not understand at which position the player was fielding. Extensive knowledge of the names of all the MLB players proved prerequisite for his keeping a scorebook through listening to MLB broadcasting. His interest in MLB never ceased when he became a dentist. He asked his mother to record the live radio broadcasting and when he was free after nine at night, he listened to the tape and kept a scorebook.
