Comments on Receiving the Awards

Tsuchiya Kaban's randoseru craftsmanship, which has continued for nearly 60 years, always begins with the desire to gently accompany children in their daily lives and support their growth. We feel that these two awards are proof that the meticulous handwork and tradition we have cherished have been recognized as modern new designs and expressions.

Moving forward, we will continue to put our heart into each randoseru, helping to add color to the irreplaceable six years of children and their families.
