The popularity of a randoseru-style backpack for schoolchildren is on the rise in Japan. Traditionally, students in Japan have carried the rigid-sided, rectangular randoseru to school. However, a newfound consumer trend indicates an upward shift to the more flexible backpack-style bag. This shift seems to reflect families' prioritizing functionality and children's comfort in their school needs. The increase in bag selections occurred recently, but precise reasons for the trend are not provided in the headline.

In Japan, the choice of a child's school bag is a significant milestone, typically occurring before a child starts school. Traditional randoseru are used uniformly in many Japanese schools and are an iconic symbol of Japanese primary education. However, the contemporary lifestyle and changes in school bag policies in some institutions might be leading to increased flexibility in bag choice.

In contrast, the US or EU usually have more relaxed policies regarding school bags, where backpacks have been a norm for decades. The type and style of backpack often reflect personal preferences rather than uniformity dictated by schools.
