Soy sauce fish

Shoyu-tai, also known as soy sauce fishes, are small fish-shaped containers for liquid condiments such as soy sauce. They were first produced in Japan in the 1950s, originally in the shape of snappers. Although their use decreased by the 21st century, they continue to be used in bento and sushi containers and airline meals.

Soy sauce fishes have spread in use as Japanese cuisine has grown popular outside of Japan. In 2025, as part of an effort to address plastics pollution, the Australian state of South Australia became the first place in the world to ban their use.
