We report the discovery of a possible nova in M31 on V-band CCD images taken on 2016-11-12.372 UT with the 1.05-m Schmidt telescope and KWFC (Sako et al. 2012, SPIE, 8446, 84466L) at Kiso Observatory, the University of Tokyo. The object is located at R.A. = 00:45:15.63, Decl. = +41:39:06.5 (equinox 2000.0; position uncertainty 0.14"). The following V-band magnitude and upper limit were obtained using the 1.05-m telescope at Kiso:
