DESCRIPTION:Speakers: Masaki Fukushima (Institute for Cosmic Ray Research\
 , The University of Tokyo)\nUltra-High Energy Cosmic Rays (UHECRs) with en
 ergy reaching 10²⁰ eV have been measured by large-scale hybrid detector
 s employing an array of ground particle detectors and air fluorescence tel
 escopes. Recent findings from Telescope Array (TA) in Utah\, USA and Pierr
 e Auger Observatory (PAO) in Malargue\, Argentina include a sudden flux de
 crease above ~10¹⁹‧⁷ eV possibly caused by the predicted Greisen-Za
 tsepin-Kuzmin (GZK) interaction of UHECR with CMBs\, measurements of prima
 ry nuclear compositions\, proton or heavier nuclei\, and hints of anisotro
 py and association with Active Galactic Nuclei (AGN) in the cosmic ray arr
 ival directions. The detectors of TA and PAO will be introduced with plans
  of near future extensions. Further RDs and technical challenges including
  the MHz/GHz radio detection from the air shower and space observation of 
 air fluorescence (JEM-EUSO\, TUS and KLYPVE) will be reviewed.\n\nhttps://
