Local seafood bowls, fresh crab, scallops, and salmon roe. Eat like a Hokkaido local.

Sankaku Market in Hakodate is a compact morning seafood market where you go to eat fresh kaisendon and buy live shellfish; plan to visit early, roughly 6:00 to 10:00, because stalls wind down by mid‑afternoon. Expect short counter restaurants where you can pick a crab or uni and have it prepared on the spot, but bring cash since small vendors may not take cards. It is an easy walk from the bay/Red Brick Warehouse area, menus often have photos so ordering is simple even with limited Japanese, and prices are higher for ready-to-eat bowls, so check what’s included before you sit down.
