  We present a distance measurement for the semiregular variable S Crateris (S
Crt) based on its annual parallax. With the unique dual beam system of the VLBI
Exploration for Radio Astrometry (VERA) telescopes, we measured the absolute
proper motion of a water maser spot associated with S Crt, referred to the
quasar J1147-0724 located at an angular separation of 1.23$^{\circ}$. In
observations spanning nearly two years, we have detected the maser spot at the
LSR velocity of 34.7 km s$^{-1}$, for which we measured the annual parallax of
2.33$\pm$0.13 mas corresponding to a distance of 430$^{+25}_{-23}$ pc. This
measurement has an accuracy one order of magnitude better than the parallax
measurements of HIPPARCOS. The angular distribution and three-dimensional
velocity field of maser spots indicate a bipolar outflow with the flow axis
along northeast-southwest direction. Using the distance and photospheric
temperature, we estimate the stellar radius of S Crt and compare it with those
of Mira variables.
