Younger samurai often became exchange students because they were ambitious, literate and well-educated. On return, some started private schools for higher education, while many samurai became reporters and writers and set up newspaper companies. Others entered governmental service. In the 1880s, 23 percent of prominent Japanese businessmen were from the samurai class; by the 1920s the number had grown to 35 percent. Philosophy Religious influences The philosophies of Buddhism and Zen, and to a lesser extent Confucianism and Shinto, influenced the samurai culture. Zen meditation became an important teaching because it offered a process to calm one's mind. The Buddhist concept of reincarnation and rebirth led samurai to abandon torture and needless killing, while some samurai even gave up violence altogether and became Buddhist monks after coming to believe that their killings were fruitless. Some were killed as they came to terms with these conclusions in the battlefield. The most defining role that Confucianism played in samurai philosophy was to stress the importance of the lord-retainer relationship—the loyalty that a samurai was required to show his lord. Literature on the subject of bushido such as Hagakure ("Hidden in Leaves") by Yamamoto Tsunetomo and Gorin no Sho ("Book of the Five Rings") by Miyamoto Musashi, both written in the Edo period, contributed to the development of bushidō and Zen philosophy. According to Robert Sharf, "The notion that Zen is somehow related to Japanese culture in general, and bushidō in particular, is familiar to Western students of Zen through the writings of D. T. Suzuki, no doubt the single most important figure in the spread of Zen in the West." In an account of Japan sent to Father Ignatius Loyola at Rome, drawn from the statements of Anger (Han-Siro's western name), Xavier describes the importance of honor to the Japanese (Letter preserved at College of Coimbra): In the first place, the nation with which we have had to do here surpasses in goodness any of the nations lately discovered. I really think that among barbarous nations there can be none that has more natural goodness than the Japanese. They are of a kindly disposition, not at all given to cheating, wonderfully desirous of honour and rank. Honour with them is placed above everything else. There are a great many poor among them, but poverty
