Ainu Cuisine: Hokkaido's Indigenous Food Tradition
Ainu cuisine represents one of Japan's oldest and most distinct food traditions — developed over thousands of years by the Ainu people of Hokkaido and the surrounding islands. Built entirely on Hokkaido's natural abundance — salmon from rushing rivers, deer from forested mountains, wild plants from alpine meadows — Ainu food is seasonal, whole-ingredient, and deeply connected to the land.
Key Ainu Ingredients
- • Chep (salmon): The most important Ainu food — eaten fresh, dried, fermented, and frozen as ruibe
- • Yuk (deer / venison): Hunted from Hokkaido forests; used in ohaw soup and dried as jerky
- • Ciporo-imo (potatoes): Introduced in the Edo period; became central to Ainu stews
- • Wild mountain plants: Giyaman (wild garlic), putchina (Siberian onion), and fuki (butterbur)
- • Kom (black bear): Ceremonially important; eaten at the iyomante (bear ceremony)
Japan formally recognized the Ainu as an indigenous people in 2019, and the government opened the Upopoy National Ainu Museum in Shiraoi, Hokkaido in 2020 — including a cultural center where visitors can experience Ainu food and cooking traditions firsthand.
Ohaw: The Heart of Ainu Cooking
Ohaw (オハウ) is the centerpiece dish of Ainu cuisine — a rich, hearty soup simmered for hours with whatever seasonal ingredients are available. While the components change by season and region, the spirit of ohaw is consistent: maximize the natural flavors of Hokkaido's ingredients with minimal seasoning.
Chep ohaw (salmon ohaw)
The classic version — fresh or dried salmon pieces simmered with wild greens and vegetables. The salmon bones and head release collagen and deep umami into the broth. Seasoned with salt alone.
Yuk ohaw (venison ohaw)
Deer meat simmered with ciporo-imo (potatoes), burdock root, and mountain vegetables. Richer and earthier than salmon ohaw, traditionally eaten in autumn and winter after the deer hunt.
Modern ohaw
Contemporary Ainu restaurants in Sapporo and Noboribetsu serve updated ohaw with refined presentations — still using traditional wild plants and Hokkaido ingredients but plated for restaurant dining.
Ruibe: Frozen Salmon in Ainu Tradition
Ruibe (ルイベ) is one of the most distinctive and celebrated Ainu food preparations — salmon (or sometimes other fish) that is frozen, then sliced thin and eaten semi-frozen. The name comes from the Ainu word meaning "thawed food."
The tradition developed as a practical Ainu food preservation method — fresh salmon was stored outdoors in Hokkaido's subzero winters, naturally freezing solid. When needed, it was brought inside and sliced before fully thawing, creating a uniquely rich, buttery texture as the fat content of the salmon partially melts on the tongue while the flesh remains firm.
Ruibe Today
Modern ruibe is made by freezing fresh salmon (at -20°C for at least 24 hours to ensure food safety), then slicing it while semi-frozen. It appears on menus at Hokkaido izakaya and Japanese restaurants as an elegant appetizer — served like sashimi but with a distinctive cold, slightly crystalline texture. Ponzu or a light soy sauce is the traditional accompaniment.
Other Key Ainu Dishes
Sakayam (fermented salmon roe)
Salmon roe fermented in salt — a traditional Ainu seasoning used to add depth to ohaw. Similar to ikura (Japanese salmon roe) but more intensely flavored through fermentation. Used as both a condiment and a seasoning ingredient.
Makayo (black soybean mochi)
A traditional Ainu sweet — sticky rice or millet pounded with black soybeans and sweetened. The Ainu equivalent of a confection, often made for ceremonies and gatherings.
Pone-taysay (fat rendered from bear)
Bear fat rendered slowly and used as a cooking fat — similar to lard but with a distinctive wild flavor. Ceremonially important in Ainu culture, as the bear (kom) holds spiritual significance.
Dried venison (yuk kemu)
Thinly sliced venison dried and smoked over alder wood — a traditional Ainu preservation method that creates a jerky-like protein food for winter stores. Available at some Upopoy museum shops.

Susukino, SapporoMany Sapporo izakaya serve ruibe as an appetizer and Hokkaido salmon preparations influenced by Ainu traditions. Look for restaurants advertising "Hokkaido sansai" (mountain vegetables) for wild plant sides.
💴 ¥800–¥2,500Food & Culture: The Spiritual Dimension of Ainu Cuisine
Ainu food is inseparable from Ainu spirituality. The Ainu worldview holds that all living things — animals, plants, rivers, mountains — are inhabited by divine spirits called kamuy. When an Ainu person kills an animal or catches a fish for food, it is understood as the kamuy temporarily taking a physical form to gift themselves to the people.
Sacred Foods & Ceremonies
- • Iyomante (bear ceremony): A ceremony where a young bear is raised and then ritually sent back to the spirit world — bear meat is consumed communally as a sacred act
- • First salmon ceremony: The first salmon of the season is greeted with prayers and offerings before the fishing season begins
- • Inaw (ritual wood shavings): Sacred objects placed beside food during ceremonies to carry prayers to the kamuy
