I will report our recent experimental studies on pionic atoms and eta'-mesic nuclei. Pionic atoms are known to provide irreplaceable information on the pion-nucleus interaction. Our recent spectroscopy of pionic atoms in (d,3He) reactions provides very high precision information on the binding energies and widths, and thus we expect more stringent constraints to be set to the pion-nucleus interaction. In the presentation, our recent activities on an experiment for eta' mesic nuclei search at GSI/FAIR will also be discussed in the context of the mass generation mechanism of the mesons.
