What is a Japanese Pan Called? A Guide to Iwashi, Donabe & More

You’re standing in the kitchen, staring at a sleek, black vessel with a wooden lid. It looks nothing like your standard frying pan or saucepan. You want to make that perfect miso soup or simmered fish dish you saw online, but the recipe calls for an Iwashi pot. What on earth is it? And why does it look so different from Western cookware? The short answer is that there isn’t just one "Japanese pan." Instead, Japan has a specific name for almost every type of cooking vessel, tailored to the food it’s designed to handle. Confusing these terms can lead to buying the wrong equipment and ending up with undercooked rice or burnt tofu. This guide breaks down the most common Japanese pans and pots, explaining what they are, what they’re called, and how to use them effectively in your home kitchen.

The Core Vessels: Pans vs. Pots

In English, we often use "pan" as a catch-all term. In Japanese culinary culture, the distinction between flat-bottomed frying vessels and deep simmering pots is strict. Understanding this difference is the first step to mastering Japanese home cooking.

The most iconic flat vessel is the Iwashi, which translates literally to "mackerel" due to its shape resembling the fish. It is a shallow, round frying pan used primarily for searing proteins like fish, meat, and tofu. Unlike a Western non-stick skillet, an Iwashi is typically made of iron or aluminum and has a slightly sloped edge to allow excess oil to drain away easily. If you are looking for a general-purpose frying pan for Japanese cuisine, this is usually the tool you need.

On the other hand, when recipes call for boiling, simmering, or stewing, you’ll encounter deep pots known as Nabeyaki (earthenware) or metal stockpots. These are not "pans" in the traditional sense but are essential for creating broths, soups, and stews. The material matters here because earthenware retains heat evenly and slowly, which is crucial for delicate flavors in dishes like Oden or Miso Soup.

Donabe: The Heart of Japanese Stews

If you only buy one piece of Japanese cookware, many chefs will argue it should be a Donabe. Also known as a clay pot, the Donabe is the quintessential vessel for slow-cooked stews and soups. It consists of two parts: a ceramic body and a matching ceramic lid, often featuring a wooden handle or knob for safety.

Why is it so popular? The porous nature of the unglazed interior allows the pot to absorb moisture and release it back into the food during cooking. This creates a unique, subtle flavor profile that metal pots simply cannot replicate. However, Donabe requires care. They are fragile and sensitive to sudden temperature changes. Never put a cold Donabe directly onto a high flame, and avoid washing it with soap if possible, as it can retain odors over time. Despite the maintenance, the results-think rich, savory Nikujaga (beef and potato stew)-are worth the effort.

Specialized Pans for Specific Dishes

Beyond the general-purpose Iwashi and Donabe, Japanese kitchens feature highly specialized pans designed for single tasks. These tools reflect the precision and efficiency valued in Japanese cooking.

• Tamagoyaki Pan: A rectangular, tapered pan specifically for making rolled omelets. The sloping sides allow the egg to roll up tightly without breaking. It is usually non-stick and small, fitting comfortably on a standard burner.
• Sukiyaki Pot: A wide, shallow cast-iron or copper pot with a raised rim. It is designed for Sukiyaki, a hot-pot style meal where ingredients are cooked tableside in sweet soy sauce. The shallow depth ensures even heating across the surface.
• Mizuyaki Pot: Similar to the Sukiyaki pot but with a deeper base, used for Mizuyaki, a milder version of the dish where ingredients are boiled in dashi rather than seared.
• Kama-yaki: While technically a griddle, the Kama-yaki is a large, flat cast-iron plate used for making Okonomiyaki (savory pancakes). Its size allows multiple pancakes to cook simultaneously, making it ideal for family meals.

Material Matters: Iron, Clay, and Aluminum

The name of the pan is only half the story; the material determines its performance. Traditional Japanese cookware relies heavily on three main materials, each with distinct properties.

Cast Iron is the backbone of durable Japanese cookware. Pots like the Maitake (a type of heavy-duty iron pot) are seasoned over years of use, developing a natural non-stick surface. Cast iron holds heat exceptionally well, making it perfect for frying and searing. However, it is heavy and requires regular maintenance to prevent rust.

Earthenware, used in Donabe and Nabeyaki pots, offers gentle, even heat distribution. It is best for liquids and slow cooking but poor for high-heat searing. The key attribute here is thermal mass; once heated, it stays warm for a long time, keeping food hot at the table.

Aluminum is lighter and more responsive to heat changes than iron. Many modern Iwashi pans are made of aluminum because they heat up quickly and are easier to maneuver. However, aluminum reacts with acidic foods, so it is often coated or paired with stainless steel liners in higher-end models.

How to Choose the Right Pan for Your Kitchen

With so many options, it’s easy to feel overwhelmed. The best approach is to start with your cooking habits. Do you eat out a lot and want to recreate specific dishes at home? Or are you looking to expand your daily cooking repertoire?

If you frequently prepare rice-based meals, a basic Iwashi pan is a versatile investment. It can handle stir-fries, fried tofu, and simple protein preparations. Pair this with a standard stockpot for broths, and you cover 80% of Japanese home cooking needs.

For enthusiasts who love communal dining or slow-cooked comfort food, a Donabe adds a layer of authenticity. Just remember to check your stove compatibility. Most electric coils work fine, but induction stoves require specific magnetic bases or dedicated induction-ready clay pots.

Finally, consider the storage space. Japanese cookware can be bulky, especially cast iron pieces. Measure your cabinet space before purchasing large Sukiyaki pots or heavy Maitake vessels. A compact Tamagoyaki pan, on the other hand, fits easily in a drawer and serves as a fun, low-commitment entry point into Japanese cooking techniques.

Care and Maintenance Tips

Proper care extends the life of your Japanese cookware and improves its performance over time.

1. Season Iron Pots: After washing a cast iron Iwashi or Maitake pot, dry it thoroughly on the stove and apply a thin layer of vegetable oil. This prevents rust and builds the non-stick patina.
2. Avoid Thermal Shock: For Donabe pots, let them cool naturally before adding water. Sudden temperature shifts can crack the ceramic.
3. Hand Wash Only: Unless specified otherwise, hand wash all traditional Japanese cookware. Dishwashers can strip seasoning from iron and degrade glazes on clay.
4. Store Dry: Keep lids off or slightly ajar to allow air circulation. Trapped moisture leads to mold in clay pots and rust in iron.

By understanding the specific names and functions of these vessels, you move beyond generic "Asian cooking" labels and into the precise world of Japanese culinary tradition. Whether you choose a sturdy Iwashi for quick weeknight dinners or a cherished Donabe for weekend stews, each piece brings a unique character to your kitchen.
