"Live" Cedar Tub (Kioke) Brews for Delicious Shoyu

Cedar Tub for Shoyu

Kawashimaya's domestic organic shoyu is made by traditional cedar tub natural brewing, including the cedar tub that has been passed down since 1902.

Cedar tubs, which have been used to make shoyu since ancient times, have been steadily decreasing due to incompatibility with cost-effectiveness. It is now said that making shoyu in cedar tubs is less than 1% of domestic shoyu production.

Lactic acid bacteria and yeasts settle in the cedar tub used to make shoyu for a long time and bring out the unique aroma and taste of the brewery, which deepens the flavor. It is also scientifically proven that glutamic acid, an umami ingredient, increases by adding shoyu in a cedar tub.

Traditional Wooden Tub

That's why we continue to adhere to the ancient Japanese natural manufacturing method using traditional cedar tubs where the bacteria that have grown delicious shoyu for over 130 years have settled down.

Strong Commitment to Domestic and Safe Raw Materials

The raw materials used are organic domestic soybeans, wheat, natural salt, and freshwater. We make really safe and secure shoyu without relying on cheap raw materials and additives imported overseas.

Domestic Soybeans

About 97% of Japanese shoyu is made from overseas soybeans and fat-processed soybeans (flake-shaped soybeans excluding oil). Still, Kawashimaya's domestic organic shoyu is less than the remaining 3% of domestic soybeans. It is made using high-quality organic soybeans grown by Japanese farmers with magnificent care. Similarly, for wheat, we use only carefully selected wheat that is organic and domestically produced.

(* Currently, soybeans are produced in Hokkaido, Ishikawa, Yamagata, or Aomori, while wheat is produced in Hokkaido or Ishikawa, but it may change due to bad weather.)

Domestic Wheat

Seawater salt, which uses 100% seawater from Ako, Hyogo Prefecture, the home of salt, gives the soy sauce a deep salty taste and mellowness without horns and helps fermentation and aging.

Ako Salt

The famous water of the clear stream Sugihara River in Kita-Harima, Hyogo Prefecture, which is used as the water for preparation, gives the shoyu a soft texture.

Famous Water of the Sugihara River

Safe Ingredients are Checked with Several Thorough Inspections

To ensure the shoyu was made with safe ingredients, the domestic wheat used during the production was well-evaluated as safe raw ingredients according to Residual Pesticide Inspection, Heavy Metal Inspection, and GMO (Genetically Modified Organism) Inspection issued by SGS Japan.

The Reason Why it's not Low-salt Shoyu

Reason for Not Reducing Salt

Originally, salt serves to prevent soy sauce from rotting. Therefore, adding synthetic sweeteners as preservatives to low-salt soy sauce becomes necessary instead of reducing the salt content.

Even with additive-free shoyu, you can reduce salt intake by adjusting the amount of shoyu used for cooking.

Shoyu Making Process That Spares No Effort, Even From Step One

Koji making, which is the key to shoyu brewing, takes time and effort, so the number of breweries that make their own koji is scrimpy, but we carefully selected it based on the belief that good shoyu can't be made without good koji. We are particular about shoyu brewing, which uses carefully selected wheat and soybeans, taking 40 hours to make koji.

Koji Preparation

Koji making differs depending on the temperature and humidity, wheat and beans, so it is always a serious game.

Shoyu Koji

(* The photo is shoyu koji)

Mix the finished koji with saltwater and put it in a traditional cedar tub. To adjust the lactic acid bacteria and yeast that brew the shoyu, manually stir while checking the degree.

Stir

Without artificial temperature control, it takes more than a year to slowly ferment the mash with the power of nature to create a mellow flavor.

Moromi fermentation

Put the finished mash on a squeezing machine and carefully squeeze the shoyu. Finally, it's sterilized by heating and then bottled to make the special domestic organic shoyu.

Product Development Story

Delivering the Japanese tradition of "Cedar Tub Shoyu to the World

Large and Small Shoyu

Shoyu has long been famous as a typical seasoning in Japan. Before the Edo period, most shoyu was made from "wooden tubs" made from cedarwood. In the cedar tub, there is a yeast that can only live in the brewery, and by achieving its own fermentation, it produces the unique flavor and richness of the cedar tub that cannot be experienced by metal tank brewing. Shoyu with a deep taste is produced, but it has been steadily decreasing because it's difficult to process and cost-effective. Meanwhile, Adachi Brewery, who cooperated in the commercialization of this product, manufactures shoyu in a cedar tub that has been used for over 100 years since its establishment. We want to deliver this exceptional shoyu prepared in a cedar tub to Japanese and overseas customers. We will provide it with the expectation that customers worldwide will support it. Please enjoy the taste of our shoyu, which is different from the usually mass-produced shoyu.

Q & A About Organic Shoyu

What are the raw materials for this domestic organic shoyu?

The raw materials are domestic and organic soybeans, wheat, and natural salt from Ako. We use the famous water of the Sugihara River, a clear stream in Kita-Harima, Hyogo Prefecture.

What are the benefits of brewing shoyu in a wooden tub?

Lactic acid bacteria and yeasts settle in the wooden tub used to make shoyu for a long time and bring out the unique aroma and taste of the brewery, which deepens the flavor of shoyu itself. It is also scientifically proven that glutamic acid, which is an umami ingredient, increases by adding shoyu in a wooden tub. However, the reality is that it is steadily declining because it is not cost-effective.

Why do you stick to the natural brewing of shoyu?

If you artificially control the temperature and humidity, you can shorten the brewing period to sell it more efficiently and cheaply. However, the "deliciousness, depth of taste, and umami" are entirely different from natural brewing. In natural brewing, which takes more than a year, yeast is most active and matures in summer, but yeast is still alive and fermented gently even in the cold autumn and winter, and it is only obtained at that time. Unique flavor and mellowness are added to the shoyu.

I'm trying to live a low sodium life. So, do you sell low-salt shoyu?

Originally, salt serves to prevent shoyu from rotting. Therefore, it becomes necessary to add synthetic sweeteners as preservatives to low-salt shoyu instead of reducing the salt content. Even with additive-free shoyu, you can reduce salt intake by adjusting the amount of shoyu used for cooking.

How is dark shoyu different from other shoyu?

It is said that dark shoyu accounts for 80% of the total consumption of shoyu in general, and it is a perfect shoyu for everyday use that goes well with anything from shoyu to cooking. The salt content is about 16%, which is darker in appearance than the familiar light shoyu (salt content 18-19%), but the salt content can be said to be plain.

Please tell me the recommended usage of this shoyu!

Good quality shoyu complements the ingredients, so you can only feel the difference in the aroma and umami of shoyu when you use it in your daily cooking. The shoyu itself is rich in flavor, so even if you use other seasonings more modestly than usual, you will be satisfied with the result!
