  We present a far-infrared all-sky atlas from a sensitive all-sky survey using
the Japanese $AKARI$ satellite. The survey covers $> 99$% of the sky in four
photometric bands centred at 65 $\mu$m, 90 $\mu$m, 140 $\mu$m, and 160 $\mu$m
with spatial resolutions ranging from 1 to 1.5 arcmin. These data provide
crucial information for the investigation and characterisation of the
properties of dusty material in the Interstellar Medium (ISM), since
significant portion of its energy is emitted between $\sim$50 and 200 $\mu$m.
The large-scale distribution of interstellar clouds, their thermal dust
temperatures and column densities, can be investigated with the improved
spatial resolution compared to earlier all-sky survey observations. In addition
to the point source distribution, the large-scale distribution of ISM cirrus
emission, and its filamentary structure, are well traced. We have made the
first public release of the full-sky data to provide a legacy data set for use
by the astronomical community.
