Octopus Sashimi is a unique Japanese delicacy prized for its delicate sweetness, pleasantly firm texture, and clean ocean flavor. Known as Tako Sashimi in Japan, this elegant dish is typically prepared using premium octopus that has been carefully cleaned and lightly cooked before being chilled and thinly sliced. Served with soy sauce, fresh wasabi, and traditional garnishes, Octopus Sashimi offers a refreshing and sophisticated seafood experience that showcases the precision and artistry of Japanese cuisine.

What is Octopus Sashimi?

Octopus Sashimi, or Tako Sashimi, is a traditional Japanese dish made from thinly sliced octopus served without rice. Unlike many fish sashimi varieties that are served completely raw, octopus is most often briefly simmered or blanched before serving. This process tenderizes the meat, enhances its natural sweetness, and ensures a pleasant texture.

The sliced octopus is served chilled with classic Japanese condiments, allowing its subtle flavor to shine.

Equipment Needed

  • Serving platter
  • Small dipping bowls

Choosing the Best Octopus

Select octopus that is:

  • Fresh with a clean ocean aroma
  • Firm and glossy
  • Properly cleaned
  • Free from strong odors
  • Bright in color
  • Purchased from a reputable seafood supplier

Frozen octopus is also an excellent option because freezing naturally helps tenderize the meat.

Preparing the Octopus

Step 1: Clean Thoroughly

If using whole octopus:

  • Remove the beak
  • Remove internal organs
  • Wash thoroughly under cold running water

Many seafood markets sell pre-cleaned octopus, making preparation much easier.

Step 2: Tenderize

Rub the octopus with sea salt for several minutes.

Rinse thoroughly.

This traditional technique helps improve texture and removes surface slime.

Step 3: Simmer

Bring water to a gentle boil.

Carefully dip the octopus tentacles into the water three times before fully submerging them. This helps the tentacles curl attractively.

Reduce the heat and simmer gently for 30–45 minutes, depending on the size of the octopus, until tender. Avoid vigorous boiling, which can make the flesh tough.

Step 4: Cool Quickly

Transfer the cooked octopus immediately to an ice bath.

Cool completely before refrigerating for at least 30 minutes.

Chilling firms the flesh and makes it easier to slice.

How to Slice Octopus Sashimi

Using a sharp sashimi knife:

  • Slice across the grain.
  • Cut each piece about ⅛ inch (3 mm) thick.
  • Make smooth, even slices.
  • Avoid sawing motions.

Uniform slices create the best texture and presentation.

Arranging the Plate

Cover a chilled serving platter with shredded daikon radish.

Arrange the octopus slices in an overlapping fan pattern.

Garnish with:

  • Shiso leaves
  • Lemon wedges
  • Pickled ginger
  • Fresh wasabi
  • Thin cucumber slices

Serve soy sauce separately in a dipping bowl.

Traditional Serving Style

Serve chilled with:

  • Japanese soy sauce
  • Fresh wasabi
  • Ponzu sauce
  • Pickled ginger
  • Daikon radish
  • Green tea
  • Chilled sake (optional)

Dip each slice lightly before eating to appreciate its naturally sweet flavor.

Chef's Tips

  • Simmer gently rather than boiling vigorously.
  • Cool immediately in ice water to preserve texture.
  • Chill thoroughly before slicing.
  • Use a razor-sharp knife.
  • Slice thinly and evenly.
