My title is such B.S., just like the post by a website that rhymes loosely with “Bruce’s Feet” (I hope this doesn’t attract people with a foot fetish, although if your name is Bruce, welcome).
If you Google the “best soy sauce,” a shiesty post titled “The 8 Best Soy Sauces of 2020” pops up, and if you think I’m throwing shade for no reason, let me explain. The products listed on that site are not the “best” because saying something is the best is subjective, although they also do not cite what their criteria are in their evaluation, which may or may not be based on product quality (ingredients), taste, or price.

The other articles online have Chinese and Japanese brands all thrown together, but I will focus strictly on Japanese soy sauces, which have a very distinctive taste and style compared to Chinese soy sauces.
Soy sauce was invented by the Chinese, and if you want to know the history from China to Japan, this Japanese site soysauce.or.jp has the history of soy sauce.
The products listed in other articles are chosen to merely promote their Amazon or Instacart affiliate links. So in my eyes, their content is completely useless in regards to being “the best” because they have a clear agenda which has nothing to do with finding you the best of anything. The article should be retitled to “the best way to put some money into our pockets sucka foo.”

The History of Soy Sauce
Beyond the Japanese website with their history of soy sauce from China to Japan, Samuel Wells Williams, and his book “the Middle Kingdom, published in 1848 (original by Harvard University), A Survey of the Geography, Government, Education, Social Life, Arts, Religion & of the Chinese Empire and Its Inhabitants ; with a New Map of the Empire · Volume 2” can be read free of charge via Google Books.

Japanese Shoyu and All the Major Brands and the Types

Keep in mind, asking “which is the best soy sauce” is like asking “which is the best beer.” So I have the 3 biggest and most popular Japanese soy sauce brands listed, along with the “craft” soy sauces at the bottom link/article.
I swear tho, most beer drinkers think an IPA is the end all, be all of beers tho.
You will be more than happy using any of the top three brands listed in this article (according to Kikkoman, there are 1,300 soy sauce producers and Kikkoman owns 30% of the domestic market) although if you want to try products from regional producers in Japan, you will want to try all the craft soy sauces.
The Inclusion of Wheat of Various Ratios in Japanese Shoyu Is What Makes It Distinctive From Other Soy Sauces
Japanese soy sauces are fermented and are comprised of:
- Water
- Koji (Aspergillus oryzae)
- Soybeans (steamed and roasted)
- Crushed wheat (except for tamari which contains little to no wheat although the inclusion of various ratios of wheat gives Japanese soy sauces a nuanced flavor.)
- Salt
Compared to other non-Japanese soy sauces, Japanese shoyu is commonly non-GMO and does not contain corn syrups, artificial caramel, to hydrolyzed vegetable protein or hydrochloric acid.
Soy Sauce aka Shoyu (Japanese), Jiang You (China), Whe-ganjang (Korea)
I had to edit this blog post (1/10/23) because I ran across an article saying that Japanese shoyu was not the same as “soy sauce,” which is ridiculous. After all, it is a SAUCE MADE OF SOY, and as I read that, it reminded me why I do this blog.
The article goes on to tout how Japanese shoyu is not the same as soy sauce which is perplexing because if it is not a “soy-based” sauce, what is it or it’s origins?

Yes, shoyu is a soy sauce, and you can use “shoyu and soy sauce” interchangeably, although not all soy sauces are the same. They vary by country of origin to regional varieties (usukuchi to koikuchi for Japanese soy sauce).
In the United States, we have regional soy sauce from Hawaii by Aloha shoyu, which reflects the Japanese, Asian American, and multi-ethnic influence on the island.
So let me say that an overwhelming amount of things from around the world came from China (chicken noodle soup, ketchup, alcohol, etc), but in Japan and Korea, they can thank the Chinese (I also thank the Chinese). So if you want to avoid such silly content, head on over to the Woks of Life where you can learn all about Chinese soy sauce called “jiàng yóu.”
So is it identical to Chinese soy sauce? No, but its roots are Chinese soy sauce, and “shoyu” is the Japanese name for soy sauce. The same goes for many other countries, like Korea, which have its own name for soy sauce (crazyKoreancooking.com knows all about it).
Well, I won’t dwell on this topic, and I think most understand that you can refer to most soy sauce “interchangeably,” although you can’t dismiss the distinct regional styles by producers from around the globe.
Japanese Shoyu Compared to Soy Sauces From Around the World
If you did not grow up with soy sauce, you would lump all soy sauce together as the same or “Asian stuff,” as several media outlets have done.
It is unfortunate because it dismisses the regional distinctiveness these ingredients provide regional dishes. So a Hawaiian-style soy sauce for Japanese dishes can dramatically change a dish’s taste.
These are the ingredients of the top soy sauce brands by country (and a US state a type/tamari)
BRAND | ETHNIC TYPE | INGREDIENTS |
---|---|---|
Aloha Shoyu | Hawaiian | Water, wheat gluten, soy beans, salt, sugar, caramel coloring, sodium benzoate & potassium sorbate, a preservative. |
Kikkoman | Japanese | Water, Soybeans, Wheat, Salt |
La Choy | Chinese | Water, Hydrolyzed Soy Protein, Salt, Corn Syrup, Caramel Color, Potassium Sorbate (Preservative). |
Lee Kum Kee | Chinese | Water, salt, soybean, sugar, wheat flour, sodium benzoate added as a preservative, Disodium 5-Inosinate & Disodium 5-Guanylate as flavor enhancers. |
Pearl River Bridge | Chinese | Water, soya beans, sugar, salt, Contains: soy, wheat, sulfites. |
San-J | Japanese | Water, Organic Soybeans, Salt, Organic Alcohol (to preserve freshness). |
Sempio | Korean | Water, defatted soybean, wheat, salt, spirits, high-fructose corn syrup, yeast extract, licorice extract, sucralose. |

Tamari has little to no wheat and is one of the five types of Japanese soy sauces, but the most popular type is koikuchi (1:1 wheat and soybeans). Whereas tamari has 1% of the market share in Japan.
Tamari is historically the Japanese version of Chinese soy sauce which was a way to stretch the highly prized resource, salt, for food preservation (yea, refrigerators weren’t a thing back in the day).

The 5 Types of Japanese Soy Sauces
A condiment that has been produced in Japan for upwards of 1,000 years.

From general a general purpose soy sauce to mostly wheat and wheat free: 1.koikuchi, 2. usukuchi, 3. shiro, 4. saishikomi, and 5. tamari
Japanese soy sauce contains various ratios of soybeans and wheat to a koikuchi that has undergone a double brewing refermenting process (saishikomi).
TYPE | CHARACTERISTIC | DESCRIPTION |
---|---|---|
Koikuchi | General purpose soy sauce (strong flavored) | The most popular/common (upwards of 80%) soy sauce which consists of 1:1 of soybeans and wheat. |
Koikuchi genen shoyu | Low-sodium | 20-40% less salt. |
Koikuchi, marudaizu | Whole bean | Uses whole soybeans and takes longer to ferment so it is generally more expensive. |
Usukuchi | Lighter colored and saltier | Lighter colored but utilizes more salt than koikuchi (so quit buying it and rating the product low because of a misassumption of the product being low sodium soy sauce, I am talking to you Amazon buyers/review section). |
Shiro | “white” | Primarily composed of wheat with very little soybeans. |
Saishikomi | Double brewed | A stronger and deeper flavored soy sauce great for dipping. |
Tamari | Typically gluten-free | Mostly to all soybeans and is based on the Chinese product (a by-product of miso production) that introduced Japan to soy sauce. |

If You Want To Learn More, This Dude Has an Interesting Read
I am more than happy to promote others and one such individual is Tom Schiller who has an in-depth blog article on shoyu, and I highly suggest you check out his blog OishisoJapan.com.
Of all those brands, I’ve only tried Kikoman. It’s so popular in Vietnam that nearly every Japanese restaurant uses it 🙂 What is your personal favourite?
There is one from the Ehime prefecture that I really love as a dipping shoyu although I do not know any other specifics. It makes me hungry thinking about it.
