Accurate neutron capture cross section data of $$^{126}$$Sn, which is one of the most important long-lived fission products (LLFPs), is required in the study of transmutation of radioactive waste. However, there is only one experimental data at the thermal energy. A $$^{126}$$Sn sample for a nuclear data experiment contaminated with a large amount of tin stable isotopes, $$^{115, 117-120, 122, 124}$$Sn, because these stable isotopes also have fission yields. These isotopes have large effects on neutron-capture cross-section measurements for $$^{126}$$Sn. To obtain accurate cross-section data for $$^{126}$$Sn, a series of neutron-capture cross-section measurements of all the tin stable isotopes are required. Therefore, the measurements of all tin stable isotopes have been started with Accurate Neutron-Nucleus Reaction measurement Instrument (ANNRI) of Materials and Life science experimental Facility (MLF) in Japan Proton Accelerator Research Complex (J-PARC). In this presentation, preliminary results of the neutron-capture cross-section measurements of $$^{120, 122, 124}$$Sn are reported in the neutron energy region from 10 meV to 2 keV.
