Kendama has long been familiar to many people, and its origin is said to be France of the 16th century. The shape of the present Kendama is very limited, but by borrowing the power of the computer, it is possible to make various shapes of kendama. In this method, by optimizing the center of gravity and adjusting the mass so that the 3D model created by the designer can be regarded as a kendama ball, it can be transformed into a Kendama that is easy to play.
