Traditional Japanese Brewing · Traditional Brewing

Kikkoman Naturally Brewed Soy Sauce is crafted using the Koikuchi Shoyu (濃口醤油) brewing method, a tradition carried down from Japan's Edo period. Selected soybeans are steamed and combined with roasted wheat, then inoculated with koji (Aspergillus oryzae) to begin fermentation. Salt water is added to create moromi — the fermentation mash — which is then slowly aged for approximately 6 months (180 days), allowing nature to take its course.

During this extended fermentation, microorganisms gradually break down soy proteins and wheat starches, naturally generating around 300 distinct aroma and flavour compounds. Unlike chemically hydrolysed soy sauce, natural brewing produces a deep, complex flavour that only time and patience can create. No chemical additives, artificial preservatives, or colourings are used.

Just as European cheese matures in caves for months, wine deepens in oak barrels over time, and sauerkraut develops its character through natural fermentation, Japanese shoyu shares the same philosophy of fermentation. One hundred and eighty days in every drop — that is the essence of naturally brewed soy sauce.

Japanese-Style Uses · Estilo Japonés

Six classic ways to enjoy Kikkoman Naturally Brewed Soy Sauce in Japanese households — experience the flavour of authentic Japan.

Sushi & Sashimi
寿司・刺身
The most fundamental Japanese use — dipping fresh sashimi and sushi. The deep umami of naturally brewed soy sauce draws out the natural sweetness of the fish, completing the flavour of the ingredients with just a single drop.
Donburi
丼ぶり
Used as the seasoning base for rice bowl dishes (gyudon, katsudon, oyakodon, etc.). Simmer the soy sauce with mirin, sugar, and dashi to create a rich Japanese sweet-savoury glaze that deeply infuses the meat and onions.
Udon & Soba
うどん・蕎麦
A key ingredient in udon and soba broth (tsuyu). Combine dashi (bonito stock) with naturally brewed soy sauce and mirin to create a warm noodle soup or a cold dipping sauce (tsukedare) for chilled noodles.
Tempura
天ぷら
Used in tentsuyu — the classic dipping sauce for tempura. Add naturally brewed soy sauce and mirin to dashi stock to create a light, clean-flavoured sauce that perfectly complements the crispy batter.
Teriyaki
照り焼き
The base for teriyaki sauce. Simmer naturally brewed soy sauce, mirin, sugar, and sake in a 1:1:1:1 ratio to create a glossy, rich teriyaki glaze — perfect for chicken, salmon, or aubergine dishes.
Onigiri & Tamago
おにぎり・卵焼き
Used to season the fillings of onigiri (Japanese rice balls) or to flavour tamagoyaki (Japanese rolled omelette). Just one or two drops are enough to elevate the natural flavour of the ingredients.

Frequently Asked Questions (FAQ)
How is Kikkoman Naturally Brewed Soy Sauce different from regular soy sauce?

Kikkoman Naturally Brewed Soy Sauce is made from soybeans, wheat, salt, and water, naturally fermented and aged for 180 days (approximately 6 months). This traditional brewing method is comparable to the way European cheeses or wines develop complex flavours through ageing. Unlike chemically produced soy sauce, the 180-day natural fermentation process generates deep umami flavour and rich aroma entirely naturally. The result is a dark reddish-brown colour with a complex, slightly sweet finish behind the saltiness.

Is this soy sauce suitable for vegans or vegetarians?

Yes, Kikkoman Naturally Brewed Soy Sauce is suitable for both vegans and vegetarians. The ingredients are water, soybeans, wheat, and salt — just four ingredients, with no animal-derived components whatsoever. Please note that trace amounts of alcohol may be produced as a by-product of the natural fermentation process; those who strictly avoid alcohol are advised to contact the manufacturer directly.

Does this product contain allergens? Is it gluten-free?

This product is not gluten-free. In accordance with EU food labelling regulations (Regulation 1169/2011 Annex II), this product contains two major declared allergens: gluten (from wheat) and soybeans. Anyone with a wheat allergy, gluten intolerance (including coeliac disease), or soy allergy should avoid this product. The production facility may also handle crustaceans, eggs, fish, peanuts, milk, sesame, and sulphites; those with severe cross-contamination sensitivities are advised to contact the manufacturer (Kikkoman) directly.

Is this soy sauce Halal certified?

No, the European distribution version of Kikkoman Naturally Brewed Soy Sauce does not carry a confirmed official Halal certification. Trace amounts of alcohol may be generated as a by-product of the natural fermentation process, which may prevent Halal certification. Those who strictly follow a Halal diet are advised to contact the manufacturer (Kikkoman) directly before consumption.

How should this soy sauce be stored, and how high is the sodium content?

Before opening, store Kikkoman Naturally Brewed Soy Sauce in a cool, dry place. After opening, keep the cap tightly closed and refrigerate; use as soon as possible to maintain optimal flavour. Regarding sodium: this product contains 16.9g of salt per 100ml, which is very high. As required by EU Regulation 1169/2011, salt content is clearly stated on the nutrition label. We recommend using small amounts in cooking and minimising additional salt. Those with high blood pressure or who need to restrict sodium intake should use this product with care.
