Japanese sake is generally divided into two flavors, one with a spicy taste and the other with a sweet taste. Since the Meiji Restoration in the second half of the 19th century, the quality of sake has gradually declined, especially during the Second World War, when Japanese brewers mixed large amounts of alcohol into sake to increase the volume of brewing and make huge profits, eclipsing the unique flavor of sake.

Thus, Japanese elders called this inferior sake the sake of chaos, and praised the original pure sake as the "sake of peace". Because the sake brewing industry was affected by the "troubled times" in history, which left a bad impression on Japanese consumers, and because a new generation of Japanese people favored beer and spirits, the sales volume of sake declined year by year. Today, although the quality of Japanese sake has been restored to its original level, and the use of modern brewing technology and equipment to continuously improve the quality of products, but its products accounted for only 15% of the Japanese liquor market sales.
