In this short communication, we report neutron diffractions under high pressure from lead powder in a Paris-Edinburgh cell on the High Resolution Powder Diffractometer (HRPD) installed at JRR-3, Ibaraki, Japan. This is the kick-off experiment in Japan as a high pressure powder diffraction study using the reactor neutron source. The obtained data enable us to estimate how long beam time is necessary for the potential experiments.
