It is well known that neutron powder diffraction is very powerful tool for materials science and engineering. In J-PARC, six powder diffractometers are operating. In this paper, a brief introduction and specification for versatile powder diffractometer, iMATERIA, super high resolution powder diffractometer, SuperHRPD and special environment powder diffractometer, SPICA are shown and also some example taken from these diffractometers.
