The blazar 3C 454.3 has recently brightened up in the gamma-ray and optical regions (ATel #2181; #2200). We performed optical photopolarimetric observations with the "KANATA" 1.5-m telescope at Higashi-Hiroshima Observatory. Our preliminary analysis shows that the blazar 3C 454.3 is V=14.84+/-0.01 on 16.1 Sep 2009 (UT). The V-band magnitude is obtained with a comparison star located at RA=22:53:58.18, Dec=+16:09:06.9 (V=13.587; Gonzalez- Perez et al 2001, AJ, 122, 2055).
