We present the results of multiepoch VLBI observations for a 6.7 GHz methanol maser toward the UC H II region of W 3(OH) with Japanese VLBI Network (JVN). Based on phase-referencing VLBI astrometry, we derived the trigonometric annual parallax to be 0.598$\ \pm\ $0.067 mas, corresponding to a distance of 1.67$^{+0.21}_{-0.17}$ kpc. This is the first detection of parallax for a 6.7 GHz methanol mas...
