In the history, Japan Taisho era was a period between Meiji and Showa. From 1912-1926 to 15 years, there have been drastic changes in Japan. The waves of Taisho democratism has swept through all areas of culture.
Taisho romanticism was influenced by the romanticism that developed in Europe in the 19th century. The ideological trend of personal emancipation and the idea of the new era in the Taisho era was prevalent, and this name was used to describe these phenomena. It is also one of the most representative of Taisho romantic culture. In animation is more frequent, It is represented by literary, military, and female students.
The Taisho period was a period of unprecedented development of feminism. The rise of feminism has made the westernization of clothing no longer restricted to men. The uniform of the female student was changed from the light of the early Traditional Japanese dress to the westernization of the sailor suit. One of the more popular is collocation of the small sleeves kimono and pants. Female students often wear Western-style hairstyles, tie large ribbons, kimonos with the arrowheads pattern, and wear Lengthened pleated skirts. Also used to popular to wear lace-up boots.

Rokumeikan is a guild hall of the similar salon hall built in Tokyo after the Meiji Restoration in Japan, It is a place where the nobles and nobles of westernization come together for elegance.
High-level females in the period of Rokumeikan, wear a dress with a bustle to keep the hip bigger. Holding umbrellas and fans with long handles to imitate Western women clothing and talk. It was also a Western-style dress that was introduced into Japan in the early days. To this day, Japanese royals will still wear the improved version of this dress when attending important events. 
The military is an important part of the ruling class during the Taisho period. After the Meiji Restoration in 1868, Japan initially formed modern militarism. Subsequently, various areas established a modern Japanese militarist system. After 1895, it continued to develop. After the “26 June coup” in 1936, it went to extreme fascism. Although there was a rise of democracy during the Taisho era and a constitutional movement broke out, the generals of the Bushido spirit had always been in a dominant position, laying a profound social foundation for militarism. Among them, the general is the highest rank. About 41 Japanese army generals were born during the Taisho era.
