The Yamaroku Tsurubishio Shoyu is a premium Japanese barrel-aged soy sauce made of high quality natural ingredients and by following traditional techniques.
Tsurubishio Shoyu has dark, almost black color, very rich and strong scent, and mellow taste.
The soy sauce is aged in large wooden barrels which have been used for over 150 years since the foundation of Yamaroku. The passage of time makes the lactic acid bacteria and yeasts settle tightly inside the barrels, giving the soy sauce a distinctive flavor and taste.
What makes this soy sauce different from the others is Yamaroku's "re-preparation method". While conventional soy sauces are sold into market after 2-years-fermentation, Yamaroku once extracts the soy sauce from the barrel, puts it into the barrel again, and ferments it for another 2 years. This makes the flavor very rich and full.
Close the bottle cap tightly once opened, and store it in a cool and dark place. Avoid direct heat or sunlight.

- NBNicolae B.Verified BuyerRated 5 out of 5 stars12/16/25Umami bomb!
It is the most complex flavour I have tasted so far. It's a premium product, much better than supermarket soy sauce.

Yamaroku Soy Sauce
After watching a YouTube video about the authentic barrel-aged preparation of Yamaroku soy sauce, I decided to order a bottle to try it for myself — and that decision completely changed my kitchen.
It has now been a few years since I first tasted it, and no other soy sauce compares. The depth of flavor, rich aroma, and true umami of Yamaroku make every other brand taste flat in comparison. Even though it costs nearly ten times more than Kikkoman, I simply cannot go back — there’s not enough flavor or character in anything else.
