  We present basic properties of $\sim$3,300 emission line galaxies detected by
the FastSound survey, which are mostly H$\alpha$ emitters at $z \sim$ 1.2-1.5
in the total area of about 20 deg$^2$, with the H$\alpha$ flux sensitivity
limit of $\sim 1.6 \times 10^{-16} \rm erg \ cm^{-2} s^{-1}$ at 4.5 sigma. This
paper presents the catalogs of the FastSound emission lines and galaxies, which
will be open to the public in the near future. We also present basic properties
of typical FastSound H$\alpha$ emitters, which have H$\alpha$ luminosities of
$10^{41.8}$-$10^{43.3}$ erg/s, SFRs of 20--500 $M_\odot$/yr, and stellar masses
of $10^{10.0}$--$10^{11.3}$ $M_\odot$. The 3D distribution maps for the four
fields of CFHTLS W1--4 are presented, clearly showing large scale clustering of
galaxies at the scale of $\sim$ 100--600 comoving Mpc. Based on 1,105 galaxies
with detections of multiple emission lines, we estimate that contamination of
non-H$\alpha$ lines is about 4% in the single-line emission galaxies, which are
mostly [OIII]$\lambda$5007. This contamination fraction is also confirmed by
the stacked spectrum of all the FastSound spectra, in which H$\alpha$,
[NII]$\lambda \lambda$6548,6583, [SII]$\lambda \lambda$6717, 6731, and
[OI]$\lambda \lambda$6300,6364 are seen.
