In order to investigate the hole doping dependence of the spin-gap behavior in Y123 system, the temperature dependence of the nuclear spin-lattice relaxation time T_1 of Cu(2) site was measured in Y(Ba_<1-x>La_x)_2Cu_3O_y system. The long-range antiferromagnetic ordered states in x ≥ 0.4 confirmed by the Cu(2) NMR signal around 90 MHz ensure that the system is in the lightly doped region, at least in x ≤ 0.3. Well-de-fined spin-gap behaviors were observed at least in x ≤0.1. Considering the previous result for YBa_2Cu_3O_<6.63>, the spin-gap temperature, T_s, which is defined as the peak temperature in (T_1T)^-1(T), increases linearly with the decrease of the hole content per unit cell in CuO_2 sheet, P_<sh>(x), which was evaluated on the basis of the diagram by Tokura et al. and our results for oxygen content y. This result places one restriction on the theoretical model for the spin-gap behavior.
