Experimental evidence for the mass and the chiral condensate of hadrons is still poor. To challenge this situation we aim to measure meson mass inside the nucleus through $K^{+}K^{-}$ decays in proton-nucleus collisions at J-PARC. In this presentation we will show the experimental proposal (E88), and the status of preparation.
