Sinuous-root style
Resembling the Yose-Ue style, but all the trunks are connected by a single root system. It consists of a primary tree with multiple stems, each of which has emerged from various points of the sprawling roots and grown into a tree.
In nature, trees are forced into all kinds of shapes under the influences of weather, wind and placement. Consequently, bonsai trees can have many shapes and sizes and, depending on their way of growing, they are grouped into various styles and shapes.
Maybe some shapes seem strange and unnatural, but they are all based on the way trees grow in nature. Each tree, however, has its own character and within a certain style there is still an enormous variety. Usually a bonsai tree is given its name according to its shape or the number of trunks it has.

Though nowadays, without renouncing these styles, more importance is attached to the artistic values of movement, harmony and the coherence of the tree.
