LHC-ATLAS experiment started taking proton-proton collision data with sqrt(s)=13TeV. Making use of these data, the discovery of new physics beyond the standard model and more precise measurements of the standard model including Higgs boson property can be expected. At the same time, the development of the detector system for the high-luminosity LHC, which is expected to start in 2026, are in progress. Nagoya group contributes to the development of the advanced muon trigger system. In this talk, I will review the LHC-ATLAS upgrade project and show the current achievement of our activities.
