In the international thermonuclear experimental reactor (ITER), a lot of plasma diagnostic system will be employed for generation, control, and understanding of burning plasmas. Here, contribution from the knowledge and techniques which are obtained at existing tokamaks to ITER diagnostics is important. In this talk, recent progress of diagnostics development in JT-60U is presented. The contents are as follows: (1) development of high power and high repetition rate single mode CO laser for collective Thomson scattering, (2) development of Thomson scattering diagnostic with application of Fourier transform spectrometer, (3) fast measurement of neutron emission profile using digital signal processing, (4) computer tomography for divertor plasma spectroscopy, and (5) dust measurement using fast TV camera
