The main or most important tree in display, it is the core of the trees shaping the formation of trees having more than one trunk, such as kabudachi (multiple trunks), netsuranari (a chain of roots), yoseue (a group of trees brought together for planting) and ishi-tsuki bonsai planted on a rock. The manifestation of a view changes according to the shape of the main tree and its power and expression greatly influence the value of a bonsai tree as an object of appreciation.
