Seasonal Sashimi, known in Japanese as Shun no Sashimi (旬の刺身), is one of the purest expressions of Japanese cuisine. The word "Shun" (旬) refers to the peak season when an ingredient is at its freshest, most flavorful, and most nutritious. Rather than serving the same seafood year-round, Japanese chefs carefully select fish and shellfish that are naturally abundant during each season, ensuring the highest quality and taste.

In Japan, seasonal eating is deeply rooted in culinary tradition. From the sweet sea bream of spring to the rich fatty yellowtail of winter, each season offers unique seafood that reflects the rhythm of nature. Seasonal sashimi is commonly featured in kaiseki meals, omakase dining, seafood restaurants, ryokans, and festive celebrations.

What Is Seasonal Sashimi?

Seasonal Sashimi is a platter of raw, sushi-grade seafood chosen according to the current season. Instead of following a fixed recipe, chefs build the platter using the freshest seafood available from local waters.

Each season highlights different textures and flavors:

  • Spring emphasizes delicate, mild fish.
  • Summer features lean and refreshing seafood.
  • Autumn brings richer, slightly fattier fish.
  • Winter showcases luxurious, high-fat seafood prized for its buttery texture.

This philosophy ensures every sashimi meal is unique and closely connected to nature.

Preparing the Seafood

Step 1: Keep Everything Cold

Pat each fillet dry with paper towels.

Avoid sawing back and forth.

  • Salmon: medium-thick slices
  • Yellowtail: slightly thicker
  • Scallops: sliced horizontally
  • Squid: lightly scored before slicing

Soak in ice water for 10–15 minutes to make it crisp.

Wash and dry:

  • Shiso leaves
  • Herbs
  • Lemon wedges
  • Edible flowers

Keep chilled until serving.

Arranging the Seasonal Sashimi Platter

Alternate light and dark fish to create visual balance.

How to Enjoy Seasonal Sashimi

Traditional tasting order:

  1. White fish
  2. Shellfish
  3. Lean fish

Lightly dip the fish into soy sauce.

Apply wasabi directly to the sashimi instead of stirring it into the soy sauce, following traditional Japanese etiquette.

Take time to appreciate each variety individually before moving to the next.
