ツナ refers specifically to canned or processed tuna, not fresh tuna. From English "tuna."

CONTRAST WITH (まぐろ):

  • ツナ: canned/processed tuna — used in sandwiches, salads, and onigiri
  • (まぐろ): fresh tuna — used for sushi, sashimi, and seafood dishes

This distinction is important: you would never call sushi tuna ツナ, and you would not call canned tuna (まぐろ).

COMMON COMPOUNDS:

  • ツナ(かん): can of tuna
  • ツナサラダ: tuna salad
  • ツナサンド: tuna sandwich
  • ツナマヨ: tuna mixed with mayonnaise (very popular onigiri filling)

CULTURE:
シーチキン (Sea Chicken) is a well-known brand name for canned tuna in Japan, sometimes used generically like "Band-Aid" in English. ツナマヨ is consistently one of the top-selling onigiri flavors in convenience stores.
