Present status and perspectives of the superheavy element (SHE) chemistry at RIKEN are reviewed. A gas-jet transport system for the SHE chemistry has been installed in the focal plane of the gas-filled recoil ion separator GARIS at the RIKEN Linear Accelerator. The performance of the system was appraised using 206 Fr and 245 Fm produced in the 40 Ar-induced reactions on 169 Tm and 208 Pb, respectively. The α particles of 206 Fr and 245 Fm separated with GARIS and transported by the gas-jet were clearly identified under desired low background condition with a rotating wheel system for α spectrometry. The high gas-jet efficiencies over 90% are independent of the beam intensity up to 2 particle μA. A gas-jet coupled SHE production system and a safety system for the usage of radioactive targets were also developed on the beam line of the RIKEN K70 AVF Cyclotron. The gas-jet transport of 255 No and 261 Rf produced in the 238 U( 22 Ne,5n) 255 No and 248 Cm( 18 O,5n) 261 Rf reactions, respectively, was conducted for the future Sg chemistry by 248 Cm( 22 Ne,5n) 265 Sg.
