As the development of Beppu Onsen progressed, the demand for bamboo crafts as souvenirs increased on a par, which led to improvements in quality.As a part of this, training of craftsmen began not only
under the apprenticeship system of the private sector but also at
educational institutions. The Industrial Apprenticeship School was founded in 1902, where they started to teach new techniques in
making flower baskets and square shaped baskets by teachers invited
from outside the prefecture.
