We have proposed the construction of a spectrometer at J-PARC designed for the detection of high-mass dimuons produced in the interactions of 50 GeV primary proton beams. We have also proposed the acceleration of polarized proton beams at the J-PARC facility. Through the detections of the Drell-Yan events, a broad physics program addressing various issues in QCD is pursued. In the Drell-Yan transverse single-spin asymmetry measurement, we can explore the Sivers effect which is closely related to the orbital angular motion of partons inside the proton. Many other rich programs of spin-dependent structure function physics are carried out through the measurements of unpolarized, singly polarized, and doubly polarized Drell-Yan processes.
