The toroidal and poloidal rotations of edge magnetic fluctuations in a high beta , low q tokamak plasma ( beta p>or=1,qI<2), which has a specific q profile and is self-organized through a relaxation process, and the role of the rotations for the relaxation to a stable state are investigated. The magnetic deformation starts rotating at the initial relaxation process when the plasma relaxes to a toroidally symmetric plasma. In the stable relaxed state, ballooning-like magnetic deformations rotate nearly along the magnetic lines of force. The bulk plasma rotates with the deformations. The rotation is also accelerated by each relaxation process. In this experiment, the low q plasma in the relaxed state (qI<2) is associated with plasma rotation both in the toroidal and poloidal directions, which suppresses the magnetic fluctuations, and with beta P higher than a critical value. This enables a broad pressure profile with a sharp edge density gradient, which is inherent in the high beta relaxed plasma, to be realized and the confinement to be improved. The rotation speed becomes higher with these effects, and finally the high beta relaxed state is established. The series of phenomena occurring here resembles the L-H transition
