Hiroshima by John Hersey:
He succumbed to the Japanese baseball mania. The Hiroshima players were at first called, in English, the Carps, until he pointed out to the public that the plural for that fish, and for those ballplayers, had no “so.” He went often to watch games at the huge new stadium, not far from the A-Bomb Dome—the ruins of the Hiroshima Industrial Promotion Hall, which the city had kept as its only direct physical reminder of the bomb. In their early seasons, the Carp had dismal records, yet they had a fanatical following, something like those of the Brooklyn Dodgers and the New York Mets in their lean years. But Dr. Fuji rather mischieviously rooted for the Tokyo Swallows; he wore a Swallows button on the lapel of his jacket.
