This technology provides a way to directly observe terahertz waves generated inside a nonlinear crystal in a terahertz wave parametric generator. [Solution] The terahertz wave observation device 101 comprises a terahertz wave generating nonlinear crystal 1 that generates terahertz waves 3 from excitation light 2 by optical parametric generation, an excitation light source 21 that incidents excitation light 2 onto the terahertz wave generating nonlinear crystal 1, a probe light source 22 that incidents probe light 5 onto the terahertz wave generating nonlinear crystal 1, a first prism coupler 31 for causing the probe light 5 to be incident inside the terahertz wave generating nonlinear crystal 1, and an imaging device 41. The imaging device 41 is characterized by imaging the detected Stokes light 6 generated by the interaction between the probe light 5 and the terahertz waves 3 generated by the terahertz wave generating nonlinear crystal 1.
