We have performed the NMR, magnetic susceptibility, electrical resistivity and Hall effect measurements on a recently discovered heavy-electron compound U3Au3Sn4. The system is found to be in the incoherent Kondo state above about 40 K. Even under the presence of a large residual resistivity, the onset of coherence in the electronic system becomes evident below about 20 K in both p(T) and but it does not manifest itself in T1-1(T). Observed almost T-independent T1-1(T) below about 20 K, however, is not considered as due to development of strongly g-depend-ent spin fluctuation (SF), since an analysis in terms of the Wilson ratio rather suggests a localized character of the SF.
