About the Brewing Society of Japan

About us

The Society offers brewers information on brewing technology through research and investigation in addition to presiding over the “Nippon Jōzō Gakkai”, conference as well as educating brewers in technical skills.
The purpose of the Society is to deepen the understanding of brewing among the Japanese people by performing the duties stated above and is to contribute to the formation of their rich food culture.

The Brewing Society of Japan was established in 1906 and was authorized as an incorporated foundation in 1915.
Thereafter, for 85 years, the society has supported the progress and development of Japanese brewers by supplying pure yeast cultures, publishing books on brewing and performed other related duties.
By the administrative system revision of our country, the Japanese Government authorized the Society as an organization to perform business with more widespread public interest as an incorporated foundation. Therefore we registered our Society as new “Public Interest Incorporated Foundation Brewing Society of Japan” on September 1, 2011 and made a fresh start.

1. Research and technological development on brewing

We investigate the characteristics of brewing microbes to maintain their own natures, the analytical methods of brewing products, and manufactural process controls.

2. To help our members through their brewing studies, technological evelopments, and promote their practical use.

1) Through the scientific conference “Nippon JM zM Gakkai”, we provide our member researchers and technicians a forum to present and announce their achievements and discuss these.

2) We offer advice on technical problems of brewers and reply to the consultative questions on brewing from anyone. Moreover, we accept the analysis or sensible evaluation of brewing products and offer necessary materials or information for them. (Charging a fee in some cases)

3) We hold the following seminar which serves in the education of brew masters and coworker technicians. The general public is also invited to attend. In these seminars, we confer an attendance certificate on students who attend the sake brewing beginners’ seminar or the practical sake tasting training course. Furthermore, we confer a title of “Master (Mistress) of Sake Tasting” on the student who obtains results that are higher than a constant standard in the course, and also confer a memorial plaque for particular excellence.

[2] Yeast cells are harvested and washed with sterilized water to remove the medium.
→ After strict quality checks, the cells go to a bottling process [3].
[3] Yeast cells are bottled to an ampoule and heat sealed.
[4] Labelling is the last process for the completed product. Procedures [2] and [3] are performed in a sterile room.

Publication of The Journal of Brewing Society of Japan

The Journal of Brewing Society of Japan (J. of Brew. Soc. Japan) is a monthly bulletin of the Society. This journal has continued to be published since the establishment (1906) of our society without suspending publication, even in times when paper was a valuable commodity during wartime and the postwar period.
The journal “Jōzō-kyōkai-zasshi” (vol.1-9) changed its name to “Nippon Jōzō-kyōkai-zasshi” (vol.10-82) and “Nippon Jōzō-kyōkai-shi” (vol.83-present) respectively.
The articles have always attracted the attention of people who have interest in brewing technology since the publication of the periodical and continue being essential sources of information.
Since 1987, original scientific reports have been examined and authorized by scientists and published.
All articles of the journals (except for some of those such as advertisements) have been computerized and anyone who accesses Journal@rchive. can read the articles from vol. 1 to those of 1 year ago.
