Besides drastic changes to the social structure of Japan, in an attempt to create a strong centralized state defining its national identity, the government established a dominant national dialect, called "standard language"(標準語,hyōjungo), that replaced local and regional dialects and was based on the patterns of Tokyo's samurai classes. This dialect eventually became the norm in the realms of education, media, government, and business.[11]
