We study J-kink domain walls in D=4 massive CP1 sigma model. The domain walls are not static but stationary, since they rotate in an internal S1 space with a frequency ω and a momentum k along the domain wall. They are characterized by a conserved current Jμ=(Q,J), and are classified into magnetic (J2<0), null (J2=0), and electric (J2>0) types. Under a natural assumption that a low energy effective action of the domain wall is dual to the D=4 DBI action for a membrane, we are lead to a coincidence between the J-kink domain wall and the membrane with constant magnetic field B and electric field E. We also find that (Q,J,ω,k) is dual to (B,E,H,D) with H and D being a magnetizing field and a displacement field, respectively.
