To investigate the static and dynamic magnetic properties on the uranium-based superconductor UTe, we measured the NMR Knight shift 
and the nuclear spin lattice relaxation rate 1/
in 
by Te-NMR on a Te-enriched single-crystal sample. 1/
in is much smaller than 1/ in 
and c, and magnetic fluctuations along each axis are derived from the 1/ measured in 
parallel to all three crystalline axes. The magnetic fluctuations are almost identical at two Te sites and isotropic at high temperatures, but become anisotropic below 40 K, where heavy-fermion state is formed.
