The first test of the Kugo-Ojima colour confinement criterion by the lattice Landau gauge QCD simulation is performed. The parameter \(u\) which is expected to be \(-1\delta_b^a\) in the continuum theory was found to be \(-0.7\delta_b^a\) in the strong coupling region. The data is analysed in connection with the theory of Zwanziger. In the weak coupling region, the expectation value of the horizon function is negative or consistent with 0.
