The book contains the papers presented in the French Japan Symposium on Nuclear Structure Problems, held in January 2011 at RIKEN Wako Campus with 100 participants. Based on the long history of collaboration between France and Japan in the field of nuclear physics, various problems in recent and future studies are discussed. Emphasis is on the structure of nuclei far from the stability, reactions involving stable and unstable nuclei, nuclear processes and properties in astrophysical interest, synthesis of super-heavy elements, and instrumentation and accelerator projects.
