Who are modan boi and modan garu?

Terms "modan boi" and "modan garu"are variants of romanization of Japanese words that literally mean 'modern guy' and 'modern girl'". These expressions are used to describe young people who follow modern fashions and trends, especially in the context of Japanese culture. They can refer to both clothing styles and general life views and behaviors that reflect more globalized and contemporary influences. The terms arose in Japan during the period of urban culture growth and modernization. They became popular in the 1920s and 1930s, during an era known in Japan as the Taisho period (1912-1926). During this time, Japan was undergoing intense Westernization and modernization in many areas of life, including technology, education, industry, and culture. The capital of Japan, Tokyo, and especially the Ginza district, have become centers of fashion and youth culture. "Modan garu" became a popular symbol of new female identities that moved away from traditional roles and sought education, self-expression and participation in public life. Women began to dress in Western clothes, do sports and participate in city entertainment. "Modan boi" also symbolized a modern, young Japanese man who is open to Western ideas and lifestyles.
