Tsukudani: A Representative Local Dish of Tokyo | Complete Guide from History to Recipes and Established Shops

Tsukudani is a traditional local dish representing Tokyo and a symbol of Japanese food culture with a history of over 400 years. Born as a preserved food made by simmering seafood and seaweed in soy sauce, sugar, and mirin until concentrated, it continues to be loved by many households today. This article comprehensively introduces tsukudani as a local dish of Tokyo, from its historical background and manufacturing methods to modern preservation efforts.

What is Tsukudani | Traditional Local Cuisine Proud of Tokyo

Tsukudani (佃煮) is a dish made by simmering small fish, shellfish, seaweed, and other ingredients in seasonings such as soy sauce, sugar, and mirin until the moisture evaporates. Due to its rich flavor and ability to be stored for long periods, it was treasured as an important preserved food during the Edo period.

This dish, born in the area around Tsukuda in Chuo Ward, Tokyo, became known as “tsukudani” after the place name. As a companion to rice and as a snack with sake, it has become an indispensable presence at the Japanese table.

Main Characteristics of Tsukudani

• Rich flavoring: A sweet and savory taste based on soy sauce and sugar
• Long shelf life: Can be stored at room temperature by evaporating moisture
• Diverse ingredients: Uses various foods such as small fish, shellfish, seaweed, and kelp
• High nutritional value: Rich in calcium and minerals

History and Origin of Tsukudani | Deep Connection Between Tokugawa Ieyasu and Tsukuda Island

The history of tsukudani is deeply intertwined with the establishment of the Edo shogunate. Its origins lie in a special relationship between Tokugawa Ieyasu and fishermen from Tsukuda village in Settsu Province (present-day Osaka Prefecture).

Tokugawa Ieyasu and Fishermen of Tsukuda Village

In the early Edo period, Tokugawa Ieyasu received substantial support from fishermen of Tsukuda village in Settsu Province in battles including the Siege of Osaka. The fishermen presented fresh fish and also assisted Ieyasu by transporting soldiers by boat during wartime.

Recognizing their achievements, Ieyasu granted the fishermen of Tsukuda village the special privilege of fishing tax-free anywhere in the country. Grateful for this favor, the fishermen decided to conduct their fishing business in a location closer to Ieyasu and to present fish to him regularly.

Migration to Edo and the Birth of Tsukuda Island

In 1590 (Tensho 18), when Tokugawa Ieyasu entered Edo, the fishermen from Tsukuda village also decided to migrate to Edo. Then in 1644 (Shōho 1), they moved to a sandbar at the mouth of the Sumida River and named it “Tsukuda Island” after the name of their home village.

At that time, Tsukuda Island became the center of fishing in Edo Bay (present-day Tokyo Bay) and became an important location supplying fresh seafood to the town of Edo. The fishermen invited Sumiyoshi Shrine from their homeland and established a Sumiyoshi Shrine on Tsukuda Island as their place of faith.

Birth of Tsukudani as Preserved Food

During the Edo period, there was no refrigeration technology, and fish spoiled easily, especially in summer. Fishermen on Tsukuda Island devised a method of simmering excess small fish and unsold fish in concentrated seasoning to avoid waste, and to secure food for times when they could not go fishing.

By simmering in soy sauce and sugar to evaporate the moisture, tsukudani was born, a food that could be stored for long periods even at room temperature. Initially made as offerings at Sumiyoshi Shrine festivals and as preserved food for fishermen, it gradually spread among the townspeople of Edo due to its deliciousness and convenience.

The ingredients used in tsukudani are diverse, and manufacturing methods have developed to make use of the characteristics of each food ingredient.
