Three--nucleon scattering offers a good opportunities to study dynamical aspects of three-nucleon forces that are momentum, spin and iso-spin dependent.
At RIKEN the experimental programs of the deuteron-proton scattering at 70-300 MeV/nucleon are on going with the aim of exploring three-nucleon forces.
In this contribution, representative experimental results of deuteron--proton elastic scattering are presented.
The data are compared with state-of-the art theoretical predictions based on realistic bare nuclear potentials.
