Fujita wrote eight books on business strategy. His first book, The Jewish Way of Doing Business, explained that Jews had taken over the business world and exhorted his readers to use Jewish business methods to become rich themselves. The book was also part autobiography, in which Fujita drew parallels between antisemitism and the discrimination he himself faced because of his Kansai dialect. (He also believed that Jews had settled in Osaka some 1,000 years ago, which was why people from the area were craftier businessmen.)
