  We present an optically-selected cluster catalog from the Hyper Suprime-Cam
(HSC) Subaru Strategic Program. The HSC images are sufficiently deep to detect
cluster member galaxies down to $M_*\sim 10^{10.2}M_\odot$ even at $z\sim 1$,
allowing a reliable cluster detection at such high redshifts. We apply the
CAMIRA algorithm to the HSC Wide S16A dataset covering $\sim 232$ deg$^2$ to
construct a catalog of 1921 clusters at redshift $0.1<z<1.1$ and richness
$\hat{N}_{\rm mem}>15$ that roughly corresponds to $M_{\rm 200m}\gtrsim
10^{14}h^{-1}M_\odot$. We confirm good cluster photometric redshift
performance, with the bias and scatter in $\Delta z/(1+z)$ being better than
0.005 and 0.01 over most of the redshift range, respectively. We compare our
cluster catalog with large X-ray cluster catalogs from XXL and XMM-LSS surveys
and find good correlation between richness and X-ray properties. We also study
the miscentering effect from the distribution of offsets between optical and
X-ray cluster centers. We confirm the high ($>0.9$) completeness and purity for
high mass clusters by analyzing mock galaxy catalogs.
