The development of the kinetic particle model for the extraction region in negative hydrogen ion sources is indispensable and helpful to clarify the H- beam extraction physics. Recently, various 3D kinetic particle codes have been developed to study the extraction mechanism. Direct comparison between each other has not yet been done. Therefore, we have carried out a code-to-code benchmark activity to validate our codes. In the present study, the progress in this benchmark activity is summarized. At present, the reasonable agreement with the result by each code have been obtained using realistic plasma parameters at least for the following items; (1) Potential profile in the case of the vacuum condition (2) Temporal evolution of extracted current densities and profiles of electric potential in the case of the plasma consisting of only electrons and positive ions.
