Kodama Brewing Co., Ltd.: a brewery that produces Akita’s representative miso, soy sauce, and refined sake. Our founder, Yonenosuke Kodama, began brewing soy sauce in 1879 (Meiji 12), and established the brewery in what is now Katagami City (prev. Iitagawa Town). In 1907 (Meiji 40), our business structure was reorganized to be that of a company, and we were established as Akita’s representative producer of soy sauce and miso.

In addition to brewing miso and soy sauce, in 1913 (Taisho 2) we started to brew sake, and sent out the “Taiheizan” sake brand—named after the most known and loved mountain in the region. In 1933 (Showa 8), we presented Japan’s first chilled sake, “Reiro-Taiheizan”, and for the next 9 consecutive years, it placed first among 5000 or so other sake brands exhibited at the Annual National Sake Competition. As a result, “Taiheizan” achieved national recognition, and became a well-known sake brand representative of Akita.

Recently, we have been increasing our efforts in the production of special designation sake (tokuteimeishoshu). As we are producing sake using rice cultivated by our neighborhood farmers, we hope local farmers are excited by and will prosper from the thought of selling sake from their hometown. As we have come to treasure our region, we here at Kodama Brewery embrace that sentiment when brewing our sake.

Product Features

<Production Process>
With an emphasis on refined sake and special designation sakes, such as ginjoshu, we dedicate our attention to the time and labor intensive “Akita Kimoto Sake Production Method”, Akita’s traditional sake production method. With our special motosuri (grinded steamed rice) machine, we thoroughly smash rice to achieve a paste, and set our preparation temperatures to an unconventionally high 13 degrees C (55 degrees F). This accelerates the nitrate reduction reactions, lactic acid fermentation, and sugar conversion process, yielding a reimagined kimoto production process that preserves these traditional mechanisms while reducing the need for labor, achieving completion in 22-25 days.

For our ginjo miso, which is an all-natural miso, the initial preparation takes place in the mid-winter. It then slowly ferments until the summer, and matures when it gets cold again, in the fall and winter. Once the weather gets warmer, in spring or summer, we dig it out. It is a year and a half long process that takes its time, and hands itself off to nature to work its magic during the fermentation process.

All of our soy sauce is brewed naturally. We fill cedar buckets, made with over 100 year old Akita cedar trees, with brine water and our house-made koji (made from defatted soybeans and smashed wheat through roasting). A roughly year and a half long fermentation and maturation process is needed in order to make soy sauce that suits Akita’s climate and cooking. Some even need three years to mature. The cedar buckets used in the process are made from the heartwood of Akita cedar, with 1 sun 2 bu (~around 3.5 cm) thick rims and 4 to 5 sun thick (~12-15 cm) bottoms. Due to there no longer being cedar trees large enough to make these buckets, they are no longer newly made.
