Abstract : Axion as dark matter has been increasingly attractive, although it was originally introduced in some extensions of the Standard Model to resolve a mysterious fine-tuning in quantum chromodynamics (QCD). While the QCD axion dark matter scenario is a certainly interesting possibility, its dominant production mechanism is still inconclusive. The precise estimate of the abundance of the axion dark matter has a large impact on the direct search for the QCD axion as the ballpark for the natural axion mass will depend on it. We will discuss the current status of QCD axion dark matter, its on-going issues, and future prospects.
