鴨鍋 Kamo nabe is a traditional Japanese duck hot pot that has been part of winter food culture around Lake Biwa in Shiga Prefecture for centuries. Thinly sliced duck breast and sweet green onions simmer together in a rich soy-based broth, producing a depth of flavor that beef or chicken hot pots rarely match. It is a winter dish with a clear season, a clear region, and a very clear reason why people keep returning to it.
What is Kamo Nabe?
Kamo nabe (鴨鍋) is a Japanese hot pot dish built around duck meat as the central ingredient. The broth is typically made from kombu and bonito dashi, seasoned with light soy sauce, sake, mirin, and a small amount of sugar. Duck breast meat, sliced thin with the skin on, goes into the pot alongside green onions, grilled tofu, and seasonal vegetables. You eat each piece while the duck is still slightly pink at the center. Fully cooked duck toughens and loses its best quality.
It belongs to the nabemono family of Japanese one-pot cooking, cooked at the table. In Shiga, it is traditionally prepared in an iron pot in the eastern and northern parts of the prefecture, and in an earthenware pot in the western and southern areas. Some specialist restaurants also serve tsukune, a minced duck meatball, alongside the sliced breast. This gives you two very different textures from the same bird in the same pot.
Why is Kamo Nabe a Shiga Specialty?
The connection between Shiga Prefecture and duck hot pot is ecological as much as culinary. Lake Biwa, Japan’s largest freshwater lake, sits at the heart of Shiga. Every autumn, wild ducks including mallards migrate from Siberia and spend the winter around the lake and its surrounding wetlands. For generations, local fishermen would occasionally find ducks caught in their nets alongside their usual catch. Rather than discarding them, the fishermen cooked what they had.
That accidental beginning gradually became a deliberate tradition. Wild duck from the lake region became a seasonal delicacy. Over time, domestically raised ducklings, a cross between wild duck and domestic breeds, replaced wild-caught birds at most restaurants. The taste differs slightly, but the regional identity of the dish remains firmly tied to the Lake Biwa landscape and its winter ecology.
The result is one of those dishes where geography and season genuinely explain the flavor. Duck from this area, in this season, eating a specific diet before harvest: these factors are part of what makes 日本の冬鍋 Japanese winter hot pot from Shiga taste like it does. For other regional nabe traditions from the Kansai area, the Kansai food guide covers the full picture.
When is Kamo Nabe Season?
The season for kamo nabe runs roughly from November through March. This aligns with the migratory duck season around Lake Biwa and with the colder months when duck meat is at its best. Duck accumulates fat during the cold months to stay warm, and that fat is what gives winter duck its characteristic sweetness and depth.
Several specialist restaurants in Shiga only serve kamo nabe during this window. At Sumimoto in Nagahama, for instance, the duck nabe is available strictly from October to March. At Oume Yamashiroya in Tokyo, the season runs October to April. Outside these months, the dish simply is not on the menu. That seasonal limitation is part of what keeps the anticipation alive from year to year.
What Does Kamo Nabe Taste Like?
The flavor is richer and more layered than chicken or pork hot pot. Duck has a pronounced savoriness that comes from its dark, well-exercised muscle meat. The fat in the breast, particularly when the skin is left on, adds a gentle sweetness as it renders into the broth. That combination of red meat depth and fatty sweetness is what makes duck a compelling hot pot protein.
The green onions are not a supporting character here. They absorb the duck fat as they cook and become sweet and silky. The relationship between duck and leek in this dish is genuinely symbiotic. Neither is quite as good without the other. The broth itself deepens over the course of the meal as the duck juices release into the liquid. By the time you are halfway through the pot, the soup has become something quite different from what it started as.
The 鴨とねぎの鍋 duck and green onion hot pot combination is considered a classic pairing in Japanese cuisine. The phrase “kamo ga negi wo shotte kuru,” which roughly means “the duck arrives carrying its own leeks,” is a well-known Japanese idiom for an unexpectedly perfect situation. The dish is the origin of that saying.
Why Does Duck Taste Better in Winter?
This is worth understanding, because it explains why seasonal eating matters for this dish specifically.
Migratory ducks build up body fat reserves before and during their winter migration. That fat serves as insulation and energy storage in cold water environments. In culinary terms, it means the birds are at their fattest and most flavorful during the November to March period. The fat in duck is predominantly unsaturated, which means it remains soft and liquid at lower temperatures than saturated animal fats. When it renders into the broth, it integrates smoothly rather than solidifying into an unpleasant film.
The red meat of the breast is dense with myoglobin, the protein that gives dark meat its color and its iron-rich, savory flavor. Eating it slightly undercooked preserves the tenderness and the full flavor of the meat. This is why nearly every kamo nabe specialist emphasizes: cook the duck only until the color changes, then eat immediately.
Ingredients: What Goes Into Kamo Nabe
Essential ingredients
Duck breast with skin is the core ingredient. Thinly sliced from the breast, it cooks in seconds and should be eaten while still slightly pink. Green onions (negi) are the essential vegetable partner. They absorb the duck fat during cooking and sweeten considerably. Neither of these can be substituted without fundamentally changing the dish.
Standard additions
Grilled tofu (yaki-tofu) holds its shape in the broth and absorbs the duck flavor well. Konnyaku and chrysanthemum greens (shungiku) are common additions that provide textural contrast. Celery appears in some Shiga versions, which is somewhat unusual for a Japanese hot pot but adds a clean, slightly bitter note. Duck tsukune meatballs, made from minced neck and cartilage meat, are offered at specialist restaurants and add a second, richer duck experience to the pot.
The broth
The standard Shiga broth uses kombu dashi as its base, seasoned with light soy sauce, sake, mirin, and sugar. Some restaurants use a darker soy sauce with a warishita-style sauce similar to sukiyaki. The ratio and style varies by establishment, and this difference in broth accounts for much of the variation between restaurants. Eggs are often served for dipping, following the same custom as sukiyaki.
How is Kamo Nabe Different from Other Hot Pots?
The clearest comparison is with sukiyaki, which uses a similarly sweet soy-based broth and is also eaten with raw egg. The main difference is the protein. Duck brings a deeper, more assertive flavor than thinly sliced wagyu beef. The duck fat is more pronounced, and the meat has a mineral quality that beef sukiyaki does not have.
Compared to mizutaki, which uses plain water and no seasoning in the broth, kamo nabe is considerably bolder. The soy and mirin sauce means the broth is seasoned from the start, and the duck enriches it further as cooking progresses. Mizutaki asks the ingredient to speak for itself in plain water. Kamo nabe lets the broth and duck build something together.
Against shabu-shabu, kamo nabe is slower and richer. Shabu-shabu is a light, quick-dip method using mild dashi. Kamo nabe simmers at the table and deepens over the meal. They are genuinely different eating experiences, not variations on the same idea.
How to Make Kamo Nabe at Home
Ingredients (serves 2 to 3)
| Ingredient | Amount |
| Duck breast with skin, thinly sliced | 800g |
| Green onions (negi), cut into 5cm pieces | 4 stalks |
| Celery, cut into pieces | 2 stalks |
| Grilled tofu (yaki-tofu) | 1 block |
| Eggs (for dipping) | 4 |
| Kombu dashi stock | 1,000ml |
| Sake | 100ml |
| Light soy sauce | 130ml |
| Sugar | 100g |
Combine the kombu dashi, sake, light soy sauce, and sugar in a saucepan. Heat gently until the sugar dissolves completely. Taste the broth at this stage: it should be sweet and savory with a clean soy flavor. Adjust with a little more soy or sugar if needed before transferring to your hot pot vessel.
Slice the duck breast as thinly as possible, keeping the skin attached. A sharp knife and partially frozen meat makes clean slicing much easier. Arrange the slices on a plate to bring to the table. Do not pre-cook the duck.
Pour the broth into the pot and bring to a simmer on a portable table burner. Add the tofu, celery, and green onions to the broth first. Let them cook for two to three minutes before adding the duck. The vegetables need more time than the meat.
Lay the duck slices over the vegetables and broth. Watch carefully. As soon as the color changes from deep red to a lighter pinkish-grey on the surface, lift the pieces and eat immediately. This takes thirty seconds to a minute depending on thickness. Do not wait for the duck to look fully cooked through.
Crack a raw egg into individual dipping bowls. Beat lightly. Dip the duck and vegetables in the egg before eating. Add new ingredients to the pot in stages throughout the meal. If the broth reduces, add a small amount of plain dashi to top it up.
The most important rule: cook duck only until the color just changes, then eat immediately. Fully cooked duck becomes tough and loses the sweetness that makes the dish worth eating.
Duck Meat: What’s in It
Duck meat has a different nutritional profile from chicken. It contains higher levels of vitamin B1 and B2, both of which support energy metabolism. The iron content is notably high, roughly six times that of chicken breast, which contributes to the meat’s characteristic deep flavor and its dark color. The fat in duck is predominantly unsaturated, meaning it remains liquid at relatively low temperatures and integrates into broth rather than solidifying.
Worth saying clearly: kamo nabe is a hot pot dish, not a health supplement. Duck is a flavorful and reasonably nourishing protein. Enjoy it for the taste and the experience, not for any specific health claim.
How Much Does Kamo Nabe Cost?
Prices vary widely depending on the quality of duck used and the restaurant setting. At casual local restaurants in Shiga, expect to pay roughly 2,500 to 6,000 yen per person. Mid-range specialist restaurants in Shiga or Tokyo typically fall in the 4,000 to 8,000 yen range for a full course. High-end ryotei-style restaurants with long histories and premium wild or farm-raised duck can exceed 10,000 yen per person, but the quality of the meat, the atmosphere, and the service tend to justify the cost for a special occasion meal.
Where to Eat Kamo Nabe: Recommended Restaurants
Nayamago (納屋孫) — Edo-Period Ryotei in Shiga
Nayamago is the most historically significant kamo nabe restaurant in Shiga Prefecture. It traces its origins to the Edo period and operates out of a traditional building that retains a calm, historic character. This is the right choice for a formal kamo nabe experience in the dish’s home region. Reservations are required and must be made at least two days in advance. The duck nabe here is not a casual drop-in meal.
Sumimoto (住茂登) — 130 Years and Wild Duck in Nagahama
Sumimoto in Nagahama has been operating for 130 years, with a focus on Lake Biwa fish and seasonal Shiga ingredients. Their kamo nabe is made with wild duck and available only from October to March. The price point is accessible at 2,999 yen per person, which makes it one of the more approachable options for a genuine Shiga kamo nabe experience. A full duck meat course is also available for those who want to explore different preparations of the same bird in one sitting.
Oume Yamashiroya (青梅 山城屋) — Classic Atmosphere in Tokyo
For those in Tokyo who want to try kamo nabe without traveling to Shiga, Oume Yamashiroya in western Tokyo provides a genuine seasonal version. The restaurant has a Showa-era Japanese house interior with a balcony overlooking the garden. Kamo nabe starts at 2,600 yen for one to two people, which is reasonable for the quality and setting. Available from October to April only.
Final Thoughts
鴨鍋 Kamo nabe is one of those Japanese winter dishes that rewards patience. The season is short. The best restaurants require reservations. The duck must be eaten at exactly the right moment. All of that deliberateness is part of what makes it feel special when everything comes together. It is more elegant than most hot pots, and the combination of duck fat and sweet leek in a soy broth is genuinely hard to replicate with any other ingredient.
If you are building a winter nabe itinerary, mizutaki from Fukuoka offers a lighter, chicken-based contrast. Sukiyaki uses a similar sweet soy broth with beef, which makes for an interesting direct comparison. And motsunabe from Fukuoka is another deeply flavored winter hot pot worth knowing.

Kamo Nabe FAQ
What is kamo nabe?
Kamo nabe (鴨鍋) is a traditional Japanese duck hot pot. Thinly sliced duck breast with skin and sweet green onions simmer together in a sweet soy-based broth made from kombu dashi, light soy sauce, mirin, and sake. It is cooked at the table, with pieces eaten as soon as the duck changes color, and is most closely associated with Shiga Prefecture and Lake Biwa.
Why is duck hot pot a Shiga specialty?
Lake Biwa in Shiga Prefecture is a major wintering ground for migratory ducks arriving from Siberia each autumn. Fishermen around the lake historically caught ducks accidentally in their nets and began cooking them as a seasonal food. This accidental tradition became a deliberate regional specialty. The lake’s ecology and the winter migration cycle are directly connected to the dish’s identity.
When is the best season for kamo nabe?
The season runs from November through March. Duck accumulates fat during the cold months, and this winter fat is what gives the meat its sweetness and depth of flavor. Many specialist restaurants only offer kamo nabe during this period. Outside the season, the dish is simply not available at traditional establishments.
What does kamo nabe taste like?
The duck has a deep, savory flavor with a mild gaminess and a sweet quality from its rendered fat. The green onions absorb the duck fat and become soft and sweet. The broth is sweet-savory, with a clean soy base that deepens as the meal progresses. It is richer and more complex than chicken or pork hot pot.
How is kamo nabe different from sukiyaki or shabu-shabu?
Kamo nabe uses duck as the protein and is specific to winter. Sukiyaki uses thinly sliced wagyu beef in a similar sweet soy broth and is available year-round. Shabu-shabu uses a much lighter dashi broth and involves briefly swishing meat through the liquid rather than simmering it. Kamo nabe sits between these two in terms of richness: bolder than shabu-shabu, with a more distinctive protein flavor than sukiyaki.
Why is duck cooked only briefly in kamo nabe?
Duck breast meat becomes tough and loses its sweetness when fully cooked through. The correct technique is to cook it only until the color changes from red to light pink-grey on the surface, then eat immediately. The interior should still be slightly pink. This preserves the tender texture and the sweet fat quality that makes the dish worth eating.
What vegetables go best with kamo nabe?
Green onions (negi) are essential and the most important vegetable in the dish. Grilled tofu absorbs the broth well and provides textural contrast. Celery is a Shiga-specific addition that appears in traditional versions. Chrysanthemum greens and konnyaku are also common. The vegetable selection is deliberately restrained to let the duck and broth remain the focus.
How much does kamo nabe cost at a restaurant?
A typical restaurant serving in Shiga costs roughly 2,500 to 6,000 yen per person. Mid-range specialist restaurants fall in the 4,000 to 8,000 yen range. High-end ryotei with premium duck can exceed 10,000 yen per person. The price reflects the quality of duck sourced and the level of service and atmosphere.
Can I make kamo nabe at home?
Yes. The process is straightforward: combine kombu dashi with soy sauce, mirin, sake, and sugar for the broth. Add vegetables first, then thinly sliced duck breast and cook briefly. Serve with raw egg for dipping. The main challenge is sourcing good duck breast. A specialty butcher or Japanese grocery is the most reliable source outside Japan.
