Samurai were many of the early exchange students, not directly because they were samurai, but because many samurai were literate and well-educated scholars. Some of these exchange students started private schools for higher educations, while many samurai took pens instead of guns and became reporters and writers, setting up newspaper companies, and others entered governmental service. Some samurai became businessmen. For example, Iwasaki Yatarō, who was the great-grandson of a samurai, established Mitsubishi.
