The “Best” Japanese Soy Sauce (Shoyu) Brands

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products listed on this site are not the “best” because saying something is the best is subjective, although they also do not cite what their criteria are in their evaluation, which may or may not be based on product quality (ingredients), taste, or price.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 products listed 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.”

What I plan on providing you is an overview to Japanese shoyu and all the major brands and the types.

They are in a room made completely out of wood with several large round holes which are large vats for brewing soy sauce. The two men are using large wooden paddles to most likely stir the concoction below.
Yuasa in Wakayama is called the birthplace of soy sauce which is a big flex on the rest of Japan because who doesn’t use soy sauce? Image courtesy of Yuasa soy sauce.

The other article has Chinese and Japanese brands all thrown together, but I will focus strictly on Japanese soy sauces which has a very distinctive taste and style compared to Chinese soy sauces.

The inclusion of wheat in Japanese shoyu is what makes it distinctive from other soy sauces.

Oh you magical beans, and if you wonder what beans Jack and the Beanstalk was using, it was soybean because this bean is the reason why we have edamame, tofu, miso, natto, to soy sauce.

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 wheat gives Japanese soy sauces a deeper 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.

3 major Japanese soy sauce brands.

The largest and most dominant is Kikkoman with Yamasa and then Marukin following.

MARUKIN

“The Shodo Island production brewery includes a natural fermentation “cellar” dating back to the early 1900’s where the soy sauce is produced in approximately 300 wooden barrels made of Japanese Cedar. This facility-one of Japan’s largest natural breweries-has a production capacity that comprises around 30% of the naturally brewed soy sauce made in wooden barrels in Japan.”

– Marukin

Founded: soy sauce manufacturing came to the Shodo islands around the 1600’s, but the Marukin brand was established in 1907.

In the words of Marukin about their products: Marukin enjoys a sterling reputation as one of the top five soy sauce brands in Japan. Along with its namesake soy sauce Marukin offers a range of soy-related seasonings as well. It is based on Shodo Island, among Japan’s top four soy sauce production areas. In testimony to its high profile and popularity throughout Japan, Marukin is beloved across the country for its delicious flavor and high quality.” – Moritakk

About Kikkoman: it is the most popular brand of soy sauce in Japan and the United States and is the largest shoyu manufacturing company in the world which is also the company responsible for introducing shoyu to the West.


YAMASA

www.yamasausa.com

Soy sauce manufacturers use different kinds of Koji mold, and we use a unique strain of mold called YAMASA Aspergillus that we have nurtured over hundreds of years, since the Edo era.”

– Yamasa

Founded: Yamasa was founded in 1645 and the head office is located in Choshi, Chiba, Japan.

In their words about their products:we insist on making our products through traditional methods. Our soy sauce has a delectably rich flavor with a crisp, spicy aroma and brilliant red color. The preferred brand selected by many of Japan’s finest restaurants, YAMASA produces a slow-brewed soy sauce that is fermented and free of all artificial flavorings.” – Yamasa

There are a number of small to artisanal producers in Japan.

Beyond the major soy sauce breweries, there are supposedly over 1,500 shoyu producers in japan.

  • Just a few of the companies are: Choko, Daitoku, Fujikin, Inoue, Kishibori, Marunaka, Marushima, Mitsuboshi, Suehiro, Yamashin, Yugeta.

Types of soy sauces.

  • 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.
  • Shiro (white): is primarily composed of wheat with very little soybeans.
  • Saishikomi (double brewed): a stronger and deeper flavored soy sauce great for dipping.
  • Tamari: is mostly to all soybeans and is not that popular and only accounts for low single digit market share in Japan.

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.

    1. 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.
