Recent progress in low energy muon physics

The paper summarizes recent activities in low energy muon physics with a special emphasis on 1) μSR studies on high Tc superconductor, 2) thermal muonium in vacuum, 3) muon catalyzed fusion and 4) repolarization of the negative muon. Also, a status of the ultra‐slow muon facility as well as perspective for a new accelerator plan is presented.
