In this talk, I will discuss why previous experiments and theoretical considerations inevitably lead us to consider K* and K1 in nuclear matter [T. Song, T. Hatsuda and S.H. Lee, Phys. Lett. B 792, 160 (2019)]. I will also discuss the Weinberg type sum rule in the strangeness sector and derive a relation between chiral symmetry restoration and their mass difference. Using the kaon beam at JPARC, one could observe the mass shift of both of these particles in a nuclear target experiment, which will be the first step towards understanding the effects of chiral symmetry breaking in hadron masses.
