Shio Kujira-jiru is a traditional local soup from Yamagata Prefecture made with salted whale skin and fat, known as “shio-kujira.” It has long been enjoyed during the hot summer months and was traditionally regarded as a hearty dish for helping people maintain their strength during the summer heat.
Shio-kujira is also known as “koro” and is characterized by the layer of white fat attached to the whale skin. The salted whale is cut into thin strips and simmered together with vegetables such as potatoes and daikon radish.
The rich and distinctive fat from the salted whale gradually blends into the vegetables as they are simmered, creating a flavor quite different from ordinary vegetable soups. The dish offers a unique combination of savory richness and the characteristic aroma of whale.
One feature of the Yamagata style is the use of sake lees, or sake kasu, to add depth and flavor to the soup. However, recipes vary from one household and region to another. Some versions are seasoned with miso or soy sauce instead.
The choice of ingredients and seasonings often reflects the preferences and traditions of each family, making Shio Kujira-jiru a simple yet distinctive example of home-style regional cuisine.
Soups made with salted whale have traditionally been eaten not only in Yamagata but also in parts of the Tohoku region and Hokkaido. Before modern refrigeration became widely available, salting was an important way to preserve whale meat and other foods for later use.
In some regions, dishes made with salted whale were traditionally associated with winter. In Yamagata, however, Shio Kujira-jiru became particularly well known as a summer dish. The combination of whale fat and vegetables provided a substantial meal during the hot season and became part of the region’s traditional summer food culture.
Whales have historically been associated with good catches and abundance, and whale dishes were therefore sometimes regarded as auspicious foods. For this reason, Shio Kujira-jiru has been served not only as an everyday meal but also on special occasions.
Depending on the local custom, it may appear at New Year’s celebrations, weddings, and other festive gatherings. In this way, the dish has a place in both ordinary home cooking and important community and family occasions.
Shio Kujira-jiru reflects traditional food-preservation techniques and the regional culture of making full use of available ingredients. The distinctive richness of salted whale fat, combined with the natural flavors of vegetables, creates a taste that offers visitors a glimpse into Yamagata’s culinary heritage.
