J-PARC, a high-intensity proton accelerator facility in Japan, has been open to public use since December 2008, and various high-pressure experiments are expected to be conducted using its high-intensity pulsed neutron beam. The first test experiment using a Paris-Edinburgh (PE) press was performed with the Engineering Materials Diffractometer "TAKUMI". The powder diffractions of standard samples in the press were successfully obtained using two different geometries (vertical scattering geometry and horizontal scattering geometry). Although the signal was weak and there are still many issues to be solved, it has been confirmed that in situ high-pressure neutron powder diffraction is feasible at J-PARC.
