About the New Products
Yellowfin Tuna marinated in Yangnyeom
- Concept
A processed product offering a new sensation, enjoying Toyo-cho's yellowfin tuna with a deliciously spicy Yangnyeom sauce. With the desire to make local products more accessible to many people, we combined them with Korean seasoning culture to create a new, ready-to-eat product targeted at women.
- Development Purpose
Since there are few seafood processors in Toyo-cho and the distribution of raw tuna was the main focus, the means to transmit its charm outside the region were limited. Therefore, we developed processed goods utilizing local products, aiming for people to enjoy the unique deliciousness of Toyo-cho as meals at home or as souvenirs.
- Features and Highlights

The balance of sweetness and spiciness is adjusted to create a flavor suitable as a side dish for rice or an accompaniment to alcohol.
It is a highly popular new tuna product among women, combining the traditions of Tosa (Kochi) with Korean seasoning culture.
