Aomori

Sake in Aomori

Aomori Prefecture lies at the northern tip of Honshu, facing the Sea of Japan to the west, the Tsugaru Strait to the north and the Pacific Ocean to the east. The Aomori Sake Brewers Association has 18 member companies (as of September 2026). In June 2025, “Aomori” was designated under the geographical indication (GI) system, which protects the names of sake-producing regions. Its conditions are a moderate rice umami, a mellow feel in the mouth and a clean finish. Junmai ginjo and ginjo (sake made by polishing away the outer 40% or more of the rice grain and fermenting it slowly at low temperatures) add fruity aromas like melon and apple.

Mountain water and the winter cold are what support this taste. The Ou Mountains, which include the Hakkoda mountain range, run north to south through the center of the prefecture, and there are other mountains as well, such as the Shirakami Mountains, a World Natural Heritage site, and Mount Iwaki. These mountains store snowmelt and rainwater, producing plentiful underground water. In winter the Sea of Japan side gets heavy snow, and this harsh cold is put to use in ginjo brewing, which ferments sake slowly at low temperatures.

The rice and the yeast (the microorganism that carries out fermentation) have been developed by the prefecture's research institutions. From 1960, the prefecture's agricultural experiment station worked on developing shuzo kotekimai (rice varieties suited to sake brewing) that fit the cool climate, producing varieties such as “Hanafubuki,” “Hanaomoi,” “Hanasayaka” and “Gin Eboshi.” Among them, Hanafubuki is now the prefecture's standard sake rice. As for yeast, four yeasts unique to the prefecture have been developed, including “Mahoroba Hana,” which produces aromas of melon and apple.
