The origin of Kurobo is unclear. Until the
Meiji period, even the name had not been firmly established, and it existed as a common confection throughout
Kyushu. Today, wheat is still produced in Kyushu, and in the past, sugarcane cultivation and brown sugar production were also widespread in the region. It is commonly believed that farmers created Kurobō as a homemade confection using these local ingredients. It has also been eaten since ancient times in
Okinawa (
Ryukyu), a major production area of brown sugar. During
World War II, Kurobō was consumed as a food supply by the
Japanese military. Because it was inexpensive to produce and easy to mass-produce, soldiers valued it as a precious source of sweetness. Today, Kurobō is not limited to the Kyushu region but is sold throughout Japan. Due to its affordable price, it is often classified as a type of
dagashi (cheap traditional snacks), and it continues to be loved by modern Japanese people as a quick snack or portable food. == Main manufacturers ==
