Investigation of the heavy quark baryon is a key way to understand a degree of freedom to describe the hadron structure. The diquark correlation which is expected to be a degree of freedom of hadrons can be studied from the spectroscopy of charmed baryons. An experiment to observe and investigate the charmed baryons was proposed at the J-PARC high-momentum beam line. The experiment via the $$pi^- p to Y_c^*D^{*-}$$ reaction at 20 GeV/$$c$$ using the missing mass technique will be performed for the systematic measurement of the excitation energy, the production rates and the decay products of charmed baryons. From the systematic study of charmed baryons, the diquark correlation which is expectedly an essential degree of freedom to describe the hadron structure can be revealed.
