We report on the recent results of astrometic observations of H2O maser sources associated with the nearby molecular clouds with VERA. We carried out phase-referencing VLBI astrometry of H2O masers in a high-mass star-forming region Orion KL and successfully detected an annual parallax of Orion KL to be 2.29±0.10 mas, corresponding to the distance of 437±19 pc from the Sun. In addition, we obtained an annual parallax of a nearby low-mass star-forming region NGC 1333 to be 4.25±0.32 mas, corresponding to the distance of 235±18 pc from the Sun. Our results demonstrate the high capability of astrometry with VERA, which can provide the most accurate distances to nearby molecular clouds.
