北里柴三郎
The Meiji government abolished the Edo class structure and replaced the feudal domains of the "daimyōs" with prefectures. It instituted comprehensive tax reform and lifted the ban on Christianity. Major government priorities also included the introduction of railways, telegraph lines, and a universal education system. The Meiji government promoted widespread Westernization and hired hundreds of advisers from Western nations with expertise in such fields as education, mining, banking, law, military affairs, and transportation to remodel Japan's institutions. The Japanese adopted the Gregorian calendar, Western clothing, and Western hairstyles. One leading advocate of Westernization was the popular writer Fukuzawa Yukichi. As part of its Westernization drive, the Meiji government enthusiastically sponsored the importation of Western science, above all medical science. In 1893, Kitasato Shibasaburō established the Institute for Infectious Diseases, which would soon become world-famous, and in 1913, Hideyo Noguchi proved the link between syphilis and paresis. Furthermore, the introduction of European literary styles to Japan sparked a boom in new works of prose fiction. Characteristic authors of the period included Futabatei Shimei and Mori Ōgai, although the most famous of the Meiji era writers was Natsume Sōseki, who wrote satirical, autobiographical, and psychological novels combining both the older and newer styles. Ichiyō Higuchi, a leading female author, took inspiration from earlier literary models of the Edo period.
