新菊 in the wreath (read as either "Shinkiku" or "Shingiku", meaning "new chyrsanthemum", and apparently originating from the first names of the founder and his wife) is the 銘柄 (meigara), or brand name. (The bottom is exactly as Thomas says.)
The brewery (kura) is Yaoshin Sake Brewery in Iwakuni city, Yamaguchi prefecture.
(In addition to Thomas's link, here's their official homepage, which has an English version: TOP PAGE | Yaoshin Shuzo K.K.)
As bonus info, Shinkiku/Shingiku was the name of their original sake brand, but the brewery doesn't produce sake under this name anymore. These days, they are far better known for 雁木/Gangi, which can be enjoyed at many sake bars in Tokyo and elsewhere. (I've partaken on many occasions. )
(edit: confirmed via their homepage that the official reading is "Shingiku")
