What defining characteristic usually identifies a Tosa Maki or Tosa Roll?

Coating or inclusion of *katsuobushi* flakes

When encountered on modern Japanese menus, particularly in *izakaya* settings, a Tosa Maki or Tosa Roll is distinguished by the prominent presence of *katsuobushi* flakes. These potent, smoky bonito flakes are typically layered generously on the outside of the sushi roll or incorporated directly into the filling mixture. This application imparts a strong, savory, and smoky textural element that immediately signals the Tosa influence, contrasting with the milder textures of the rice and other standard fillings. This usage reinforces the importance of the dried skipjack product even in contemporary culinary applications.
