Is Katsuobushi Vegetarian?

Katsuobushi, often referred to as okaka, is a traditional Japanese ingredient made from bonito, a type of fish. The preparation process involves filleting the fish, boiling, smoking, and drying it to achieve a hard, wood-like texture. It is then shaved into thin flakes and used to impart a rich umami flavor to various dishes, such as dashi broth, soups, and as a topping for rice and noodles.
