How We Brew

  • Brewing No Matter Your Age or Experience

    In 2018, President Iwao Niizawa stepped down as toji, and our current toji became toji at age 22. She became toji within 3 years of joining the brewery and at the time she was the youngest female toji in Japan.
    Rather than brewing in a strict top-down hierarchical environment, where a veteran toji dictates the brewing process, our kurabito (brewers) collaborate, learn from, and inspire each other daily. They share their opinions and cooperate with each other in sake brewing, regardless of age, background, or gender. This environment, focused on collective growth, ensures that we are constantly striving towards and brewing the best sake.

    *Toji: The person who directs and is in charge of the brewing process at the sake brewery.

  • Groundbreaking Rice Polishing Technology

    To achieve the world’s highest polishing rate of 0.85%, our brewery uses “diamond roll” flat polishing machines.
    Although, the general polishing rate for sake is said to be around 70%, we discovered a rice polishing technique that achieves a rice polishing ratio of less than 1%.
    Moreover, a “flat polishing” machine more efficiently removes components of the rice that cause unwanted flavors and better preserves the original umami of the rice.
    To create the best tasting sake, we invest heavily to improve our technology and to expand the knowledge of our kurabito.

    Flat rice polishing (henpei rice polishing) – is a rice polishing method that focuses on the thickness of the brown rice rather than its length and width. This method results in a more refreshing and more delicate sake.

  • Devotion To Improvement

    Our brewery strives to go beyond maintaining the quality of our current sake.
    Every day we refine our techniques to ensure that our sake continuously improves. Today’s sake is better than yesterday’s, and tomorrow’s sake will be better than today’s.
    Our sense of taste is extremely important when discerning the complex flavor of sake.
    Therefore, we strive to improve our sake tasting abilities through various trainings such as matching drills and circuits exercises.
    In addition, with the cooperation of restaurants, we will blind taste an assortment of our and other brewery’s sake.
    Our brewers are highly competent in sake tasting and strictly assessing both our own products and other companies’ products.

    Matching Drills – Brewers blind taste numerous pairs of sake and have to match each sake to its proper pair.
    Circuit Exercises – Strive to improve a brewer’s tasting endurance and consistency. Brewers quickly taste and score about 60 various sakes in 3 separate rounds to test their grading consistency.

  • Minus 5 Degrees Celsius – The Perfect Environment
    Storing All Products at Minus 5℃ to Ensure Thorough Quality Control

    Almost all our sake is once-pasteurized and none of our products are twice pasteurized.
    Nama-zake, a non-pasteurized sake, is offered only during the winter season, as its quality tends to deteriorate rapidly in the heat.
    In order to deliver sake in the best condition possible we always store our sake at -5℃.
    We also store all bottled sake, from our premium sakes to our cup sakes, in refrigerators set to -5℃ to preserve the sake’s freshness for a longer period of time.
    We ask our distributors to keep our sake refrigerated at -5℃ to ensure that the sake is at its best when you, the consumer, opens the bottle.

    Pasteurization (hiire): A heat sterilization process to prolong the flavor and shelf life of the sake.

  • Fresh Stock Rotation

    Once a year, our brewery conducts a “Fresh Rotation” initiative, in which we visit our distributors and restaurants nationwide.
    Products sold throughout the year are shipped with different flavors, such as “refreshing” in summer and “robust” in winter. The goal is to collect and replace products displayed in different seasons.
    Sometimes we are invited to visit sake breweries for study purposes, and we drive about 4,000 km from Hokkaido in the north to Kyushu in the south over a period of about 2 weeks.
    Nowdays, thanks to the cooperation of our distributors, we rarely find products that are not up to our standards.
    This fresh rotation is an important time for us to meet our distributors directly, listen to the opinions of our customers and restaurants, and bring them back to the brewery.

    *This program is currently not in effect due to the Covid-19 pandemic.
