 R under multi-extreme conditions\, such as high magnetic field\, high pres
 sure and low temperature in Kobe. It covers the frequency region between 0
 .03 and 7 THz\,1 the temperature region between 1.8 and 300 K\,1 the magne
 tic field region up to 55 T\,1 and the pressure region is extended from 1.
 5 GPa2 to 2.5 GPa using the hybrid-type piston-cylinder pressure cell.3 It
  also includes mechanically detected ESR4 measurements using a commerciall
 y available membrane-type surface stress sensor\, which is the extension f
 rom our micro-cantilever ESR5. As an example\, application of high pressur
 e THz ESR to understand the pressure-induced phase transition in the Shast
 ry-Sutherland model substance SrCu2(BO3)2 will be discussed. Using our tec
 hnique\, we were able to determine the pressure where the pressure-induced
  phase transition occurs\, and obtain the pressure dependence of exchange 
 interactions in SrCu2(BO3)26. Comparison of our results with the theory wi
 ll be discussed.
