On the weekend of October 30th and 31st, Niigata's Imayotsuka Sake Brewery is hosting an autumn sake festival. The event includes a fun 1,000 yen gachapon game containing a variety of local brews, Halloween-themed photo spots, sake lucky bags available for purchase, and even desserts for sale that contain sake lees, such as a sake lees chiffon cake.
Even if you can't visit in time for the festival, the brewery is an interesting spot to check out for anyone visiting Niigata City. It was originally founded in 1767, and it's conveniently located in walking distance from Niigata Station.
