Japanese boys are often perceived as "girly" due to a combination of cultural norms, societal expectations, and the influence of media. This perception is rooted in the Japanese culture's emphasis on gender fluidity and the acceptance of diverse expressions of masculinity and femininity. According to a survey by the Cabinet Office of Japan, 57.2% of respondents believe that gender roles are becoming more flexible, reflecting a shift in societal attitudes.

The Japanese educational system plays a significant role in fostering this perception. Japanese schools often encourage boys to engage in activities traditionally associated with girls, such as ballet or cooking, which helps to break down rigid gender stereotypes. This approach is supported by the Ministry of Education, Culture, Sports, Science, and Technology (MEXT), which promotes gender equality and the elimination of gender-based discrimination.

Media also contributes to the image of girly Japanese boys. Japanese television shows, movies, and manga often feature male characters with feminine traits, which can normalize these behaviors in society. For example, the popular anime series "My Little Monster" (Kimi ni Todoke) features a male protagonist who is sensitive and caring, challenging traditional notions of masculinity.

Data from the Japan Society for the Study of Gender shows that the percentage of Japanese men who identify as "gender non-conforming" has been increasing over the years. This trend is further supported by the growing number of male fashion influencers who embrace androgynous styles, such as the popular YouTuber and fashion blogger, Ryo. These influencers help to normalize diverse expressions of gender and contribute to the perception of Japanese boys as "girly.

In conclusion, the perception of Japanese boys as "girly" is a result of cultural norms, educational practices, and media influence. These factors work together to create a society that is more accepting of gender fluidity and diverse expressions of masculinity and femininity.
