Japanese Traditional Food  Tsukudani
What’s Tsukudani?

In Japan, Tsukudani is a time-honored preserved food. The ingredients are preserved in salty-sweet style using soy sauce, sugar and mizuame sugar syrup. By slowly simmering natural ingredients, there is no need for preservatives or additives making long-lasting preservation possible.

In Japan it has become a popular companion for rice, and it can also be used in tea over rice (ochazuke), onigiri rice balls and as a partner for sake.

Natritive value

Since the whole ingredient is preserved, the natural nutritional value of the ingredient can be consumed.
Protein and minerals such as iron and calcium are plentiful in small fish etc. And in tree nuts such as walnuts, dietary fiber, B vitamins and minerals such as potassium and calcium are plentiful, not to mention the benefit of vegetable proteins.

How to eat Tsukudani

In Japan, Tsukudani is eaten on top of rice or as a side dish for rice. Our tsukudani can be eaten as a snack. In this way, the nutritional elements of natural ingredients can be eaten in a delicious form.

The Story
The Story of Tsukudani

The History of Tsukudani

Tsukudani is a preserved food that originated in Edo (now Tokyo) around 400 years ago in the Edo Period (1603-1868).In the Sengoku era prior to the Edo Period, fishermen of the village of Tsukuda (Osaka) assisted in the escape of the Tokugawa army, when Ieyasu Tokugawa (who would become the first shogun/commander of the Edo Shogunate) was being chased by enemies. At the time, the villagers shared their precious food for the escape in the form of preserved small fish. It is said that this preserved food was the original form of Tsukudani.

The Shogun Ieyasu subsequently allowed the fishermen of Tsukuda to live in Edo (Tokyo), as well as giving them special rights such as being able to supply food to Edo Castle and Samurai houses. Tsukudani therefore developed into a high-end foodstuff.
Tsukudani was originally quite simple ? salt-simmered and dried small fish and shellfish, however its preparation later developed into a more involved method by simmering the ingredients with soy sauce. Later again, with much trial and error, it became a high-end delicacy with much improved flavor and quality.
Now a high-end food, Tsukudani became prized as a souvenir item to take home, for the feudal lords who travelled to and from Edo, resulting in tsukudani becoming well-known around the country.
From the Meiji Period (1868-1912), the demand for tsukudani as an emergency and military ration grew due to its suitability as a preserved food with a high nutritional value. As a result, mass production progressed and it spread around Japan. It is now a food loved by many people with various ingredients and methods used around Japan.

The History of Tsukudani in Kanazawa and the origin of our company’s product

Kanazawa has a unique cultural foundation ? an amalgamation of the cultures of the Kansai and Kanto regions, and it flourished as one of Japan’s leading economic and cultural centers. In terms of food, various dishes developed as a result of Kanazawa’s geographical proximity to the sea, mountains and rivers, and the fresh and plentiful ingredients available.
In Kanazawa, the small fish tsukudani (as in the original version in Edo) is produced, as well as two unique Kanazawa versions using the local specialties of walnuts and goby.

Goby is a small fish of the gobiidae family that lives in clear streams. It was once plentiful in the Sai and Asano rivers which flow through Kanazawa and also neighboring Kahokugata.

Walnut tsukudani involves cooking the walnuts (harvested from Mt. Hakusan, one of Japan’s three sacred mountains) in rice sugar syrup, creating an aromatic product. Along with flavorful goby tsukudani, it is an essential dish at kaiseki meals and with sake.

Since our foundation, we have always kept the traditional taste of Kanazawa at the core of our operations. We place importance on the traditional taste of tsukudani, staying true to time-honored methods such as charcoal grilling and using fresh, quality ingredients.

Our Production Policy

At Tsukuda Shokuhin Co., Ltd., we do not use any food additives in our products.
So that our customers can taste the real flavor of the ingredients, we do not use additives.

‘Additives’ refers to many ingredients such as chemical seasonings (MSG), preservatives and colors ? all things that can easily enhance the flavor or appearance of a product, or lengthen its shelf life. However because we only choose select ingredients, we would like to place importance on the ingredient’s real flavor and taste. We want our customers to get the real thing.
At Tsukuda Shokuhin Co., Ltd., our top priority is to deliver to our customers quality ingredients without the use of food additives.

The reason
we don’t use chemical seasonings

Our skilled workers take time over each batch to maximize flavor. We only use carefully selected ingredients such as soy sauce using unprocessed soybeans and pure rice mirin (sweet sake).

The reason
we don’t use preservatives

Our main product, tsukudani, is already a preserved food so there is no need for preservatives. A decent shelf life can be achieved without the use of preservatives, by carefully simmering down the ingredients over time

Because natural colors are best.
