Tsuruoka Nihonshu

The success of the concept of brewing for quality was brought to light when, in 2004, Yamagata won more gold medals than any other prefecture at the Japan Sake Awards. The prefecture has held a top spot at the awards ever since. National tax agency data from 2017 shows that 78 percent of all sake produced in Yamagata is premium grade, compared to 34 percent nationwide.


Once the reputation of Yamagata sake became established, the next step was to protect it with a geographical indication (GI). This effort began in 2011. International agreements dictate that GIs are restricted to products that have a reputation, or quality, linked to a geographical region. Yamagata met those requirements due to its regional varieties of sake rice, yeast, and koji. Yamagata nihonshu was known for its clean and clear flavor. The biggest obstacle to registration was the agreement of the more than 50 brewers on evaluation criteria and timing. In December 2016, after much planning, negotiation, and lobbying, Yamagata nihonshu received a registered geographical indication. The first bottles to bear the “GI Yamagata” mark appeared on shelves in January 2018.


Nihonshu (sake) varies widely, in flavor, aroma, and price. Up until the mid-twentieth century, 53 small-scale brewers in Yamagata Prefecture were focused on producing inexpensive nihonshu for local distribution. Today, this snowy coastal prefecture along the Sea of Japan has become a premier sake-producing region at the forefront of the market. The varieties of nihonshu produced by well-known brewers are renowned for their light, clean flavors. Yamagata has even received the world’s first geographical indication (GI) for nihonshu.


Getting to that point had required much patience and effort. Thirty years ago, locally produced nihonshu was just another commodity. It was not even that popular among regular drinkers of nihonshu. The small, locally run family operations in Yamagata, as elsewhere throughout the country, operated solely on sales to the local market. In the 1970s, demand for sake began to decline. People born in the late 1940s onward began to develop a taste for other alcoholic beverages like wine, whisky, and shochu (clear distilled liquor, often made from potatoes). The combined result was a drop in nihonshu consumption.


Over the next 20 years, many breweries were not able to sustain their business through the downturn and were forced to close. Some breweries, however, were able to survive by changing their focus to making premium sake, a high-value product. Their new target audience was high-end customers in the urban centers around the country. There was varied success in different regions, but Yamagata’s approach of public-private collaboration in production turned around the nihonshu industry and boosted the local economy.


There are two grades of sake: tokutei meisho-shu (special designation sake) and futsu-shu (ordinary sake). Within premium-grade futsu-shu, there are three premium varieties: junmai, ginjo, and honjozo. Three criteria are considered when classifying these premium-grade varieties:


  1. Ingredients: Premium sake made with rice, rice koji (mold culture), and water is designated junmai-shu (pure rice sake). When the nihonshu also contains small amounts of distilled alcohol, it is designated honjozo.


  1. Brewing process: Sake that is brewed at low temperatures over time with highly polished rice is known as ginjo. If distilled alcohol is not added to the three basic ingredients, it is called junmai-ginjo.
