  We present 20,567 Ly$\alpha$ emitters (LAEs) at $z=2.2-7.3$ that are
photometrically identified by the SILVERRUSH program in a large survey area up
to 25 deg$^2$ with deep images of five broadband filters (grizy) and seven
narrowband filters targeting Ly$\alpha$ lines at $z=2.2$, $3.3$, $4.9$, $5.7$,
$6.6$, $7.0$, and $7.3$ taken by the Hyper Suprime-Cam Subaru Strategic Program
(HSC-SSP) and the Cosmic HydrOgen Reionization Unveiled with Subaru (CHORUS)
survey. We select secure $>5\sigma$ sources showing narrowband color excesses
via Ly$\alpha$ break screening, taking into account the spatial inhomogeneity
of limiting magnitudes. After removing spurious sources by careful masking and
visual inspection of coadded and multi-epoch images obtained over the 7 yr of
the surveys, we construct LAE samples consisting of 6995, 4641, 726, 6124,
2058, 18, and 5 LAEs at $z=2.2$, 3.3, 4.9, 5.7, 6.6, 7.0, and 7.3,
respectively, although the $z=7.3$ candidates are tentative. Our LAE catalogs
contain 241 spectroscopically confirmed LAEs at the expected redshifts from
previous work. We demonstrate that the number counts of our LAEs are consistent
with previous studies with similar LAE selection criteria. The LAE catalogs
will be made public on our project webpage with detailed descriptions of the
content and ancillary information about the masks and limiting magnitudes.
