Randoseru, traditional Japanese school backpacks, are gaining popularity among foreign tourists. These backpacks, usually used by elementary school pupils, have become sought-after souvenirs due to their unique design, durability, and cultural significance. While the specific period or the surge in popularity is not specified, this trend is seemingly prevalent in areas of Japan frequently visited by tourists.

In Japan, the use of Randoseru is steeped in tradition. It is typically gifted to children when they start elementary school and is expected to last throughout their elementary education. They symbolize the importance Japanese society places on education and hard work. The backpack being embraced by tourists could be an indication of growing international interest in deep-seated facets of Japanese culture.

In comparison, souvenirs in the US and EU typically tend to be items that are representative of their culture but do not necessarily play a functional role in daily life or bear significant societal meanings. The popularity of Randoseru among tourists in Japan may indicate a shift in souvenir preferences towards more meaningful and practical items.
