The local dish eaten at New Year's Eve in Kochi Prefecture is "Kureno-ni-nimono" (simmered dishes at the end of the year), which contains whale meat. This dish was eaten with the wish that by eating something as large as a whale, one would "become a big fish. In the days when whales were readily available, it was a common sight to see them lined up at fish shops as New Year's Eve approached. In the mountainous areas, dried whale called "koro" was an indispensable ingredient.
The port city of Muroto was responsible for Kochi's whale eating culture. Whales cross Tosa Bay as they migrate north and south across the Pacific Ocean. Fishing groups called "Kujigumi" whaled whales at that time of year. Tosa Bay is also known as the birthplace of Tosa whaling, and whaling is said to have begun in the early Edo period. Whaling in Tosa Bay continued for more than 300 years until 1936. Even today, Tosa Bay is a migratory course for whales, and whale watching and other whale watching activities are conducted there.

The "Kureno-ni-nimono" (simmered dishes at the end of the year) is also known as a good luck charm, and the custom of eating simmered whale dishes on New Year's Eve has been handed down to this day.
Whale dishes were also eaten on a daily basis in areas where whaling was practiced.

Whale has a lot of lean meat, and its belly and tongue are also treated as delicacies, so there are few parts that go to waste. Not only boiled, but also half-thawed sashimi is eaten, giving it a crispy texture. There is a wide range of variations, such as the standard "fried tatsuta" and "hari-hari-nabe" cooked with potherb mustard. In Echi-cho, there is a traditional way of eating it boiled together with Ohirakabu, a traditional vegetable.
When making the stew, the whale is first boiled in a pot. At this time, take off the scum as often as possible. If the meat is simmered too long, it will become tough, so it should be removed when the time is right. Add soy sauce, mirin, and sugar to the whale stock, season to taste, and simmer again with the pre-boiled daikon radish, carrots, and konnyaku. When the vegetables are cooked, add whale meat and kelp to finish.

After Japan stopped commercial whaling in 1988, whale meat became hard to obtain. With that, the whale eating culture has been disappearing, but restaurants and tourist facilities in Muroto City are still serving whale dishes. With the resumption of commercial whaling, whale meat is now available in small quantities in the fresh fish section of supermarkets. A project to revive traditional vegetables native to Tosa is underway, and the traditional vegetable "Ushioena" (a species of potherb mustard), which is indispensable for "Haribari-nabe" (Haribari hot pot), has been revived.
