🍲 What Is Chanko Nabe?
Chanko nabe (ちゃんこ鍋) is a Japanese hot pot stew most closely associated with sumo wrestlers. A pot of dashi-based broth sits at the center of the table, simmering with chicken meatballs, tofu, mushrooms, napa cabbage, and seasonal vegetables. Wrestlers gather around and serve themselves directly from the pot, course after course, often finishing the broth with rice or udon noodles.
Strictly speaking, "chanko" is not the name of a single dish. Inside a sumo heya (stable), any meal prepared and eaten together is called chanko — curry, grilled fish, stir-fries, even pasta. The hot pot simply became the most iconic form, because it is cheap to make in large quantities, easy to adjust for the day's ingredients, and ideal for feeding twenty hungry wrestlers at once. Over time, "chanko nabe" came to mean the stew itself in the public imagination.
Every stable develops its own house recipe, passed down from one chankocho (chanko cook — usually a lower-ranked wrestler) to the next. There is no single authoritative version.
📜 History & Origins
The word chanko is thought to derive from chan (an informal term for the stablemaster) and ko (his wrestlers) — the meals a stablemaster and his disciples share together. Early sumo stables fed wrestlers whatever was affordable and filling, but the nabe format came to dominate during the Meiji era (late 19th century), when Tokyo stables standardized on large communal pots.
The version now recognized as the "classic" chanko nabe — chicken-based, soy-seasoned, with tofu and seasonal vegetables — is commonly traced to the early 20th century. As retired wrestlers opened restaurants in the Ryogoku neighborhood near the Kokugikan arena, chanko nabe became known to the general public and, eventually, a Tokyo culinary landmark in its own right.
🐔 Why Chicken? The Two-Legged Tradition
Traditional chanko nabe is built around chicken, and the reason is pure sumo superstition. A chicken walks on two legs, which symbolizes a wrestler who remains upright and never falls. Four-legged animals — cows, pigs — are said to symbolize touching the ground with the hands, and touching the ground with anything but the soles of your feet means losing a bout.
This is folklore rather than rigid rule. Modern stables and chanko restaurants serve pork, beef, seafood, and all manner of combinations. But on the eve of a tournament, or on senshuraku (the final day), many stables still default to the chicken version for luck.
Traditional Chanko Nabe (Chicken-Based Sumo Stew)
Broth
- 1 liter dashi stock (or 1 L water + 10 g kombu + 20 g bonito flakes)
- 3 tbsp soy sauce
- 2 tbsp sake
- 2 tbsp mirin
Chicken Meatballs (Tsukune)
- 300 g ground chicken
- 1 egg
- 1 tbsp miso paste
- 1 tsp grated fresh ginger
- 1 tbsp cornstarch
- 1 chopped green onion
Vegetables & Tofu
- ¼ head napa cabbage (roughly chopped)
- 1 block firm tofu (cubed)
- 150 g shiitake or mixed mushrooms (sliced)
- 1 medium carrot (thinly sliced)
- 1 bunch chrysanthemum greens (or spinach)
- 1 negi (Japanese long onion, cut diagonally)
- 200 g udon noodles (optional, for the finishing course)
Instructions
- Make the dashi. Soak kombu in 1 L cold water for 30 min, heat until just below boiling, remove kombu, add bonito flakes, steep 2 min, strain. (Or use prepared dashi.)
- Season the broth. Add soy sauce, sake, and mirin. Bring to a gentle simmer in a donabe or large pot.
- Mix the meatballs. Combine chicken, egg, miso, ginger, cornstarch, and green onion until the mixture holds together.
- Form and simmer. Spoon meatballs into the broth (dip the spoon in water to prevent sticking). Cook 5–6 minutes until firm.
- Add vegetables in stages. Start with carrots and negi, then napa cabbage stems, mushrooms, and tofu. Simmer 5–7 minutes.
- Finish with greens. Add napa cabbage leaves and chrysanthemum greens in the last 2–3 minutes so they stay bright.
- Serve and shime. Eat directly from the pot at the table. After the main ingredients are gone, add udon to the remaining broth for the traditional finishing course (shime).
🔄 Regional & Modern Variations
Because every sumo stable develops its own chanko recipe, the dish exists in dozens of variations. Here are the most common broth styles:
| Broth Style | Base | Character |
|---|---|---|
| Shoyu (Soy Sauce) | Dashi + soy sauce + sake + mirin | The most traditional and widely used; clean, savory flavor |
| Miso | Dashi + miso paste (white, red, or blended) | Richer and more robust; particularly popular in winter |
| Shio (Salt) | Chicken stock or dashi + salt | Light and delicate; lets ingredient flavors shine through |
| Kimchi | Dashi or chicken stock + kimchi + gochujang | A modern variation; spicy and bold. Popular at some restaurants |
| Tonkotsu (Pork Bone) | Long-simmered pork bone stock | Creamy, opaque, intensely savory; breaks the "two-legged" tradition |
Beyond broth, modern chanko variations may include seafood (salmon, cod, shrimp), different mushroom varieties (enoki, maitake, king oyster), and noodle additions (udon, ramen noodles, or harusame glass noodles). The dish's inherent flexibility is one reason it has endured as the foundational sumo meal — it adapts to available ingredients and personal preference without losing its essential character.
🏮 Where to Eat Chanko Nabe in Ryogoku
Ryogoku, Tokyo's sumo district, has the highest concentration of chanko restaurants in Japan. Many are run by retired sumo wrestlers who bring their stable's recipes to the public. Here are some well-known establishments:
| Restaurant | Established | Known For |
|---|---|---|
| Chanko Kawasaki | 1937 | One of the oldest chanko restaurants in Ryogoku. Uses free-range chicken from Kyushu; follows a traditional, simple recipe. Currently run by the founder's son. |
| Chanko Tomoegata | 1976 | Founded by former wrestler Tomoegata. Offers multiple chanko courses with different broth styles (soy sauce, salt, miso, and more), each named after famous sumo wrestlers. Verify current status before visiting. |
| Chanko Kirishima | — | Run by former Ozeki Kirishima (now Mutsu Oyakata). Main branch on Kokugikan Street near Ryogoku Station; also has a branch inside Ryogoku Edo Noren. |
| Kappo Yoshiba | — | Located in the former Miyagino stable building (home of Yokozuna Yoshibayama). Features an original practice ring (dohyo) inside the dining area. Also known for sushi. |
| Chanko Dojo | — | Seven varieties of chanko nabe including the popular "Yokozuna Chanko." Wide selection makes it a good choice for groups with different preferences. |
Ryogoku Edo Noren
For a more casual experience, the Ryogoku Edo Noren food hall (housed in the former JR Ryogoku Station building) offers several small restaurants serving chanko nabe alongside other Tokyo specialty foods. A full-sized sumo ring sits in the center of the hall. This is a convenient option if you want to try chanko without committing to a full restaurant course.
⚖️ Nutrition & the Sumo Diet
A common misconception about chanko nabe is that it is an unhealthy, fattening food. In reality, the stew itself is generally quite nutritious:
- High in protein from chicken meatballs and tofu
- Rich in vegetables — napa cabbage, mushrooms, carrots, and greens provide fiber, vitamins, and minerals
- Hydrating — the broth provides fluid and electrolytes
- Relatively low in fat compared to many other hearty stews (especially the chicken-based version)
Sumo wrestlers gain and maintain their large body mass not from chanko itself being fattening, but from the volume and pattern of their eating:
- Wrestlers typically skip breakfast, training on an empty stomach in the morning
- The large midday chanko meal is followed by a nap — eating and then sleeping is believed to promote weight gain
- Enormous quantities are consumed — far beyond a normal serving size
- White rice and beer typically accompany the meal, adding significant calories
A normal-sized serving of chanko nabe — eaten as part of a regular meal without the sumo eating-and-sleeping pattern — is a balanced, healthy dish. This is one reason it has become popular with the general Japanese public, not just sumo fans.

❓ Frequently Asked Questions
What is chanko nabe?
Chanko nabe is a Japanese hot pot stew traditionally eaten by sumo wrestlers. It typically features chicken (often as meatballs), tofu, vegetables, and mushrooms simmered in a savory broth. The word "chanko" refers broadly to all meals prepared and eaten within a sumo stable. Each stable develops its own recipe, so there is no single definitive version of the dish.
Why do sumo wrestlers eat chicken instead of beef or pork?
According to sumo tradition, chicken is preferred because a chicken walks on two legs — symbolizing a wrestler who remains upright and never falls to all fours (which would mean losing a bout). Four-legged animals like cows and pigs symbolize touching the ground with hands, representing defeat. This is a superstition rather than a strict rule, and modern chanko recipes sometimes include pork or other meats.
Is chanko nabe healthy?
The stew itself is generally nutritious — rich in protein, vegetables, and minerals. Sumo wrestlers gain weight not from the stew alone but from the enormous quantities consumed, combined with white rice, beer, and a specific eating-and-sleeping schedule designed to promote weight gain. A normal-sized serving of chanko nabe is a balanced, healthy meal suitable for anyone.
Where is the best place to eat chanko nabe?
The Ryogoku neighborhood in Tokyo has the highest concentration of chanko restaurants in Japan, many operated by retired sumo wrestlers. Established restaurants include Chanko Kawasaki (operating since 1937), Chanko Tomoegata, Chanko Kirishima, and Kappo Yoshiba. Hours and availability change — verify before visiting.
Can I make chanko nabe at home?
Yes. Chanko nabe is a straightforward hot pot dish that can be made at home with widely available ingredients. The basic version uses chicken stock or dashi broth, chicken meatballs, napa cabbage, mushrooms, tofu, and root vegetables. A donabe (Japanese clay pot) is traditional but any large pot works.
