We investigate the separability of Klein-Gordon equation on near horizon of d-dimensional rotating Myers-Perry black hole in two limits :
1) generic extremal case and 2) extremal vanishing horizon (EVH) case. In the first
case , there is a relation between the mass and rotation parameters so that black
hole temperature vanishes. In the latter case, one of the rotation parameters is
restricted to zero on top of the extremality condition. We show that the Klein-
Gordon equation is separable in both cases. Also, we solved the radial part of
that equation and discuss its behaviour in small and large r regions.
