Hokkaido, Japan, centred on the Ishikari River basin. Rooted in Ainu salmon-fishing tradition and adapted by Japanese settlers, with the distinctive butter addition reflecting Hokkaido's 20th-century dairy farming development.
Ishikari nabe is Hokkaido's quintessential winter hot pot — bone-in salmon chunks simmered with root vegetables in a robust miso-based broth finished with butter. Named after the Ishikari River, one of Japan's great salmon rivers, the dish embodies Hokkaido's unique culinary identity: wild salmon from Ainu fishing tradition, miso adapted to cold-climate heartiness, and the dairy farming that distinguishes Hokkaido from mainland Japan. Butter in a Japanese hot pot is an exclusively Hokkaido addition.
The miso-dashi broth carries deep fermented umami; the salmon provides oceanic sweetness and richness; the butter creates a velvety surface and enriches every ingredient it contacts. Hokkaido's corn adds sweetness; potato adds starch that slightly thickens the broth. The overall flavour is deeply warming, rich, and complex — a cold-weather bowl designed for sub-zero temperatures.
Broth is a blend of white and red miso dissolved into dashi — generous quantity for a hearty cold-weather bowl, not a delicate miso soup. Salmon is cut bone-in in large chunks (4–5cm) — bones add body and gelatin to the broth. Hardy vegetables (potato, daikon, carrot, corn) go in first; salmon follows; leafy vegetables and tofu last. Butter melts on the surface at service, creating richness unique to Hokkaido. Ikura (salmon roe) garnish, when used, is added at the very end and bursts with briny contrast against the miso richness.
Some Hokkaido versions finish with a pour of fresh milk or light cream in addition to butter — another uniquely Hokkaido touch. The salmon head and collar, often discarded, produce the most flavourful broth sections when included. The potato and corn are distinctively Hokkaido — they're not standard nabemono vegetables anywhere else in Japan. At the table, the Hokkaido identity is signalled by these specific vegetables as much as by the salmon.
Using salmon fillets without bones — the bones are essential for broth depth and body. Adding miso-broth too delicately — this dish needs assertive miso presence. Overcooking the salmon — it should remain tender and barely cooked through. Skipping the butter finish — it transforms the broth from good to deeply rich. Using cheap Atlantic salmon when Hokkaido wild salmon is available.
