  Chimera states for the one-dimensional array of nonlocally coupled phase
oscillators in the continuum limit are assumed to be stationary states in most
studies, but a few studies report the existence of breathing chimera states. We
focus on multichimera states with two coherent and incoherent regions, and
numerically demonstrate that breathing multichimera states, whose global order
parameter oscillates temporally, can appear. Moreover, we show that the system
exhibits a Hopf bifurcation from a stationary multichimera to a breathing one
by the linear stability analysis for the stationary multichimera.
