The effective coupling of the Higgs boson to gluons determines the productionrate of the Higgs boson at the LHC and plays a crucial role to measure theHiggs properties. In this paper, we propose a novel method to extract the Higgsgluon gauge coupling information at the future lepton colliders, by utilizingthe jet charge asymmetry of the two leading jets from the Higgs boson decay.Owing to the jet charge correlation nature of the Higgs decay products, wedemonstrate that this asymmetry value would be close to one for the signal$H\to gg$, while it is always larger than one for the dominated backgrounds.With the help of the jet charge information, it is possible to constrain theHiggs gluon effective coupling very well in the future Higgs factory and thisconclusion is not sensitive to the jet charge parameter $\kappa$.
