This is the 16th publication from the Subaru High-z Exploration of Low-Luminosity Quasars (SHELLQs) project, and it completes identification of all but the faintest candidates (i.e., i-band dropouts with z_AB_<24 and y-band detections, and z-band dropouts with y_AB_<24) with Bayesian quasar probability P_Q_^B^>0.1 in the HSC-SSP third public data release (PDR3). The sample reported here also includes three quasars with P_Q_^B^<0.1 at z~6.6, which we selected in an effort to completely cover the reddest point sources with simple color cuts. The number of high-z quasars discovered in SHELLQs has now grown to 162, including 23 type II quasar candidates. This paper also presents identification of seven galaxies at 5.6<z<6.7, an [OIII] emitter at z=0.954, and 31 Galactic cool stars and brown dwarfs. High-z quasars and galaxies compose 75% and 16%, respectively, of all the spectroscopic SHELLQs objects that pass our latest selection algorithm with the PDR3 photometry. That is, a total of 91% of the objects lie at z>5.6. This demonstrates that the algorithm has very high efficiency, even though we are probing an unprecedentedly low luminosity population down to M_1450_~-21mag.2022ApJS..259...18Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/259/18CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJ/633/630 : Low-mass stars found in CFHTLS (Willott+, 2005)J/MNRAS/435/3306 : Candidate type II QSOs in SDSS III (Alexandroff+, 2013)J/ApJS/227/11 : PS1 z>5.6 quasars follow-up (Banados+, 2016)J/PASJ/70/S10 : GOLDRUSH I.
