This volume collects papers presented at the international workshop “Hadron-Nuclear Physics 09” held at Osaka, November 16-19, 2009. The series of this workshop has provided opportunities to discuss common interests of hadron and nuclear physics.Hadrons and nuclei show up different layers of phenomena governed by the same dynamics dictated by the fundamental law of the strong interaction, Quantum Chromodynamics (QCD). The basic building blocks of matter, quarks and gluons, are confined in hadrons, generating their masses dynamically and breaking chiral symmetry spontaneously....
