We present a distance determination to the Small Magellanic Cloud (SMC) using optical and near-infrared photometry from OGLE and IRSF. Applying a multiband method to V, I, J, H and K OGLE and IRSF data, we measured the SMC true distance modulus and mean reddening. Comparing our results with accurate distances to the LMC and SMC obtained from eclipsing binary systems, we conclude that the dependence of Cepheid magnitudes on metallicity is very small (< 0.07 mag/dex) in all bands.
