  A first-ever 2-dimensional celestial map of primary cosmic-ray flux was
obtained from 2.10x10^8 cosmic-ray muons accumulated in 1662.0 days of
Super-Kamiokande. The celestial map indicates an (0.104 \pm 0.020)% excess
region in the constellation of Taurus and a -(0.094 \pm 0.014)% deficit region
toward Virgo. Interpretations of this anisotropy are discussed.
