In the state of generating a double-scroll attractor, an oscillator switches between two subspaces without external force. This switching phenomenon is called the self-switching phenomenon. We recognize that investigations of the behavior of self-switching phenomena on full-cou-pled chaotic oscillators are important problems in order to clarify spatiotemporal phenomena in real physical systems. In this paper, we investigate the behavior of self-switching phenomena on full-coupled chaotic oscillators. In the sys-tem, we can observe that all chaotic oscillators switch the subspace synchronously. We call this synchronization of self-switching phenomena. Synchronization of self-switching phenomena is generated when oscillators are asynchronized. This synchronization of self-switching phe-nomena is the first observation of the existence of order in the asynchronization of chaos, which means disorder o
