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.
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. |
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.
A common misconception about chanko nabe is that it is an unhealthy, fattening food. In reality, the stew itself is generally quite nutritious:
Sumo wrestlers gain and maintain their large body mass not from chanko itself being fattening, but from the volume and pattern of their eating:
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.

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.
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.
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.
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.
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. See the recipe section above for a complete step-by-step guide.
