Cold, rich northern seas make Hokkaido a paradise for seafood — arguably the best in Japan. This is the place to feast on sweet king and snow crab, melt-in-the-mouth sea urchin (uni), glistening salmon roe (ikura), plump scallops and the freshest sashimi. The signature way to enjoy it all is a kaisendon — a bowl of rice heaped with a rainbow of raw seafood — devoured at a bustling morning market. From Hakodate to Sapporo to the far-flung fishing ports, seafood is reason enough to visit.

This guide covers the star ingredients, the kaisendon, where to eat, seasons and tips.

The star ingredients

  • Crab: king crab (taraba), snow crab (zuwai) and hairy crab (kegani) — steamed, grilled or in hotpot.
  • Uni (sea urchin): creamy and sweet, at its best in summer.
  • Ikura (salmon roe) and salmon — Hokkaido is salmon country.
  • Scallops, squid, herring and oysters round out the bounty.

Kaisendon & where to eat

  • A kaisendon piles fresh sashimi over rice — the ultimate market breakfast; pick your toppings.

  • Sushi counters across Hokkaido serve exceptional, well-priced nigiri.

Seasons & tips

  • Salmon and ikura: autumn. Oysters: winter.
  • Ask what’s in season and local that day for the best value.
