Katsuo no Tataki (Seared Bonito), also called Kochi seared skipjack, is Tosa’s classic plate of bonito flash-seared on the outside, sliced thick, lightly pounded with salt and sauce, then piled with garlic, negi and onion. Smoky outside and rare inside, it works on a home gas flame or torch if you keep the center raw-red—the signature of true tataki.
Ingredients
- Bonito / skipjack tuna (sashimi block or tataki cut) 300g
- Salt 1/2 tsp
- Yuzu vinegar (or yuzu juice from ponzu) 1 Tbsp
- Soy sauce 3 Tbsp
- Negi (Japanese leek) 1 stalk (about 20g)
- Onion a little (thinly sliced)
- Garlic 4–5 cloves
Steps
- Pat the bonito dry with paper towels. Set it on a grilling rack or skewer it and quickly sear the skin side and edges over a strong open flame (or a fish grill or torch) until only the outside is lightly charred and the center stays rare. Straw-fire is ideal; a gas burner at home is fine.
- Let the seared bonito cool once, then cut into thick sashimi slices (about 1 cm). Slicing too thin makes it look overcooked—slightly thick is better.
- Arrange on a cutting board, sprinkle with salt, and lightly pound with your palm or the side of a knife. Drizzle half the yuzu vinegar and soy sauce, then pound lightly again so the seasoning sinks in.
- Plate it and scatter plenty of thinly sliced garlic. Add sliced negi and onion to taste, then finish with the remaining soy sauce and yuzu vinegar.
- Eat right away, enjoying the aromatics and garlic with the smoky exterior and rare red center.

Notes
In Kochi, garlic is an essential garnish—use plenty, thinly sliced or minced.
If you cannot find yuzu vinegar, use bottled yuzu ponzu or rice vinegar with a splash of yuzu juice.
Straw-fire adds a unique aroma; at home the key is a short, fierce sear. Do not cook the center through—that is the point of tataki.
Fishmonger “tataki cuts” or skin-on blocks are harder to mess up. If the surface is already seared, just salt, sauce, pound, and top with aromatics.
Some shops add shiso, garlic chives, or natsu mikan zest. Autumn returning bonito is fattier and ideal for tataki.

Storage
Best eaten right away. If cut, refrigerate sealed and finish the same day; overnight the smell and texture suffer. Do not freeze rare fish.
FAQ
- Why is it called tataki?
- After salting or saucing, the fish is lightly pounded so the seasoning sinks in—that pounding gives the name, not mashing the flesh.
- No straw fire at home?
- A fierce gas sear or torch on skin and sides still gives smoke; keep the center rare.
- Must there be lots of garlic?
- In Kochi garlic is nearly mandatory for the Tosa taste; dial it down if needed, but do not skip it entirely.
- Can I use frozen bonito?
- Yes—thaw fully and pat dry before searing; sashimi-grade is safest.
Origin and history
Katsuo no tataki is a Kochi specialty: the prefecture’s fish, bonito, is seared hard on the outside, sliced thick, lightly pounded with salt or sauce, and eaten with garlic and other aromatics. It is said to have spread from fishermen’s meals, or as a shipboard trick to keep fish fresh and tame the smell.
The name “tataki” is said to come from pounding the flesh after salting or saucing so the seasoning sinks in. Searing the skin improves texture and adds smoke. It is now known nationwide, yet in Kochi it remains a staple of celebratory platter cuisine, with each home and shop tweaking sauce and garnishes.
At home, sear only the outside on a gas flame or grill, then pair yuzu vinegar and soy with garlic, negi, and onion for a Tosa-style plate.
