The 'Kanken Backpack' has become a popular item among Japanese high school girls (known as JKs). With its minimalist design and practical functions, the backpack quickly rose to fame among the youth. The trend, appearing rapidly in various parts of Japan, reflects the ever-changing tastes of Japan's young fashion enthusiasts. The reason for its popularity remains speculative, but the influence of pop culture and the integration of functionality with fashion seem to be driving factors.

In Japan, school backpacks often reflect students' tastes and fashion trends. With the rise of the Kanken backpack, people are taking note of its simple design and practicality. It is also seen as a statement of individuality among Japanese youth, especially high school girls.

Much like the popularity of the Kanken backpack in Japan, the US and EU have witnessed similar phenomena with brands like Jansport and Herschel, among others. These trends denote the influence of youth, pop culture, and fashion in shaping consumer behavior across cultures.
