Complete Guide to Kujira no Tare | History, How to Make, and How to Eat Chiba’s Traditional Local Dish from South Boso
What is Kujira no Tare?
“Kujira no Tare” is a traditional local dish that has been passed down for approximately 400 years since the Edo period in the South Boso region of Chiba Prefecture. It is a preserved food—also called “whale dried meat” or “whale jerky”—made by marinating the red meat of Tsuchikujira (sperm whale) in a unique sauce based on soy sauce and salt, then sun-drying it under the Boso sun.
In appearance, it is as black as charcoal or seaweed, with a unique shape like tree bark. This is because it is made from Tsuchikujira red meat without draining blood, so the color is black and the flavor has a distinctive character. However, this very distinctive flavor is the reason it has been loved by local people for many years.
It is generally eaten by lightly searing it and then tearing it into thin strips. It is widely enjoyed as a snack with alcohol, a side dish, and with tea. As a specialty product representing the food culture of South Boso, it continues to be supported by many people today.
Whaling Culture and History of the South Boso Region of Chiba Prefecture
Main Areas of Transmission
Kujira no Tare is a local dish of the South Boso region of Chiba Prefecture, particularly the Awa area centered on Wada Town in Minami Boso City. Wada Town is nationally known as an ongoing base for coastal whaling and has a long history of whaling spanning approximately 400 years.
The South Boso region faces the Pacific Ocean where the Kuroshio Current flows, and has long been known as a sea area where whales migrate. This geographical condition nurtured a whaling culture rooted in the region and created this unique food culture called kujira no tare.
History, Origins, and Related Events
The history of kujira no tare dates back to the Edo period. At a time when refrigeration technology had not yet been developed, it was born as a way to preserve whale meat, a valuable source of protein, for long periods.
Coastal whaling in the South Boso region is said to have begun in earnest in the early Edo period. Captured whales were utilized completely—meat for food, oil for lighting, and bones for fertilizer and crafts. Among these uses, “kujira no tare” is the red meat processed as a preserved food.
In the past, it was often made in individual households and was an indispensable part of the dining table in fishing villages. It was particularly valued as a preserved food and was also used as food to bring aboard ships and as nutrition during work breaks in agriculture.
Today, efforts to inherit the whaling culture continue in Wada Town, with kujira no tare being introduced at local traditional events and food culture festivals.
Main Ingredients Used and Characteristics of Tsuchikujira
About Tsuchikujira (Sperm Whale)
The whale used in kujira no tare is a type called Tsuchikujira, with a body length of approximately 12 meters. Tsuchikujira belongs to the family Kogiidae and inhabits the waters around Japan.
The greatest characteristic of Tsuchikujira is the deep color of its red meat. Because it is processed without draining blood, the meat color is very deep red to nearly black. When sun-dried, it becomes even darker with a distinctive appearance.
In Chiba Prefecture, it is recognized as “Boso Wada-ura Tsuchikujira” (Chiba brand aquatic product) and is positioned as an important aquatic resource in the region.

How to Make Kujira no Tare (Manufacturing Method)
Traditional Method
The manufacturing process of kujira no tare is based on traditional techniques passed down over many years.
- Meat preparation: Slice the red meat of Tsuchikujira to a size slightly larger than the palm of a hand (approximately 15-20cm). The thickness varies depending on the type of product, with the traditional hard type sliced thin and the modern soft type sliced thicker.
- Marinating in sauce: Marinate in a unique sauce based on soy sauce or salt for one night (approximately 12-24 hours). Each manufacturer has a secret sauce, and this blend is the key to the flavor.
- Sun-drying: Sun-dry under the Boso sun. Depending on the weather and season, drying for several days to a week removes moisture and increases shelf life. Sun-drying creates the distinctive flavor and texture.
