We consider the long time behavior of solutions to the initial value problem for the \complex-valued" cubic nonlinear Klein-Gordon equation (NLKG) in one space dimension. In , Sunagawa derived the L 1 decay estimate of solutions to (NLKG). In this note, we obtain the large time asymptotic profile of solutions to (NLKG).
