Here is your quick guide to Japanese cooking techniques. We break down the main 4 basics that are integral to Japanese cuisine, so you’re be ready to amp up your kitchen skills.
Japanese cuisine Washoku (和食) has a distinctive culinary style all of its own. The cooking is simple; no complicated processes, no heavy sauces, fiery spices, or fragrant herbs. All seek to preserve the natural flavors, textures, colors, and nutrients of the produce.
Mastering the cooking techniques are fundamental for making good Japanese food at home. Once you’re armed with the basic know-how, you can easily recreate Japanese food at home with locally sourced ingredients.
So, let’s get started!
4 Main Styles of Japanese Cooking Techniques
There are hundreds of cooking techniques in Japanese cuisine, but we can group them into the four main categories.
- Niru (煮る) – “simmer in liquid”
- Yaku (焼く) – “cook in direct or indirect heat”
- Musu (蒸す) – “steam”
- Ageru (揚げる) – “deep fry”
1. Niru (煮る) “Simmer”
First things first, what exactly is ‘niru’ or simmering? It is a cooking technique that uses a lower/moderate heat to gently soften foods in liquid.
The lower heat penetrates food slowly and helps to incorporating flavors while retaining the shapes. It’s less intense than boiling, but a little more aggressive than poaching.
The Japanese simmer or ‘niru’ technique usually starts with dashi (Japanese soup stock). However, it can be further defined by many distinctive styles utilizing different seasonings, ingredients, temperatures, etc.
A well-tested cooking technique, it requires seasoned knowledge of timing and selection of the best ingredients in their seasonal prime. You can basically cook any ingredients – from vegetables, meat, seafood to tofu – using the ‘niru’ or simmer technique.
There are many different approaches that fall under ‘niru’. Here are some of the basics:
- Nimono (煮物) – the umbrella of Japanese simmering
- Takiawase (炊合せ・焚合せ)
- Fukumeni (含め煮)
- Nikorogashi (煮ころがし)
- Itameni/Irini (炒め煮・炒り煮)
- Tsukudani (佃煮)
- Misoni (味噌煮)
- Nitsuke (煮付)
Nimono (煮物) basically refers to all simmered foods, where the ingredients are cooked until the liquid has mostly evaporated.
The simmering liquid is a base of dashi, sake, soy sauce and a sweetener (mirin, sugar or both). The liquid should not be soupy and drowning the ingredients, although some dishes will have some broth leftover, which is ladled over the final dish before serving.
Most nimono dishes are the comfort food for the Japanese, and the cornerstone in both “mom’s/grandma’s home cooking” and Kaiseki Ryori (Japanese fine-dining cuisine).
The most classic homey nimono is Nishime (煮しめ) or Chikuzenni (筑前煮), where various ingredients are cooked together in one pot and simmered in their own juices. We serve the dish for the everyday meal as well as celebratory occasions such as the Japanese New Years’ feast.
In Kaiseki Ryori, it is perhaps the most important course that showcases the chef’s skills. Through nimono dishes, s/he perfectly presents the seasonal ingredient in its purest yet tastiest nature to the guests. When the dish is served in a bowl, it is called Futamono (蓋物, literally “lidded thing”) or Nimonowan (煮物椀, literally “nimono bowl”).

A Kansai style of cooking where the ingredients are simmered separately to retain their distinctive flavor, color, and texture, then quickly cooked together in a light broth.
A vegetarian dish where hearty vegetables such as daikon, kabocha squash, eggplant and Koya dofu are slowly simmered in plenty of lightly seasoned broth, then left to cool to soak up the flavors. When the ingredients are cooked in a thin dashi broth, it is called Nibitashi (煮浸し).
🔪 Cook JOC Fukumeni Recipes:
- Simmered Koyadofu (高野豆腐の煮物)
- Simmered Fried Tofu and Greens (油揚げと青菜の煮浸し)
- Eggplant Agebitashi (ナスの揚げ浸し) – deep fried and simmered
Korogasu (転がす) means “to roll, tumble” and this nimono is just that – ingredients such as potatoes, taro and konnyaku are cut into large round chunks, then tossed and cooked in a sweet savory sauce.
Ingredients that are stir-fried in oil, then simmered in a strongly seasoned sauce until the liquid has evaporated, leaving a shiny glaze.
🔪 Cook JOC Itameni/Irini Recipes:
A companion to rice instead of eaten on its own, it consists of fish, shellfish, meat, seaweed, or vegetable simmered in a sweet and savory sauce for a long time, resulting in a very concentrated flavor. The name originates from Tsukuda (佃) in Tokyo, where it was first made.
🔪 Cook JOC Tsukudani Recipes:
Oily fish such as mackerel are often cooked in a Misoni, a blend of miso, dashi, mirin, soy sauce, and fresh ginger. The heavy miso flavor and ginger masks the strong taste of oily fish.
🔪 Cook JOC Misoni Recipes:
- Saba Misoni (鯖の味噌煮)
Nitsuke is a sake based simmer, applying usually to white fish, both whole fish and fillets. The sake helps remove the fishy odor and tenderizes the flesh, and the alcohol cooks off in the process.

- Kinmedai Nitsuke (金目鯛の煮付け)
2. Yaku (焼く) “Cook in Direct/Indirect Heat”
The simplest and the oldest form of cooking, ‘yaku’ includes all manners of cooking by exposing ingredients to direct or semi-direct heat. This includes grilling over an open fire, frying in a pan, or roasting in an oven. The method removes the bitterness, draws excess moisture, and brings out the inherent flavors.
While the Japanese use charcoal grilling, there’s no aromatic smoky flavors like in American BBQ. The charcoal is smokeless, odorless and emits high heat for quick grilling, which is perfect for bite-sized cuts of meat and vegetables, or small whole fish.
- Shioyaki (塩焼)
- Teriyaki (照焼)
- Yuanyaki (幽庵焼)
- Kushiyaki (串焼)
Salt is the only seasoning in Shioyaki “salt cooked” foods, where seafood such as fish, lobster, squid and shellfish are salted immediately before grilling. For fatty fish like mackerel and hamachi, salt is used to draw moisture and oil out of the flesh before grilling.

Teriyaki refers to the method of cooking where a protein is cooked for a shiny glaze, hence the “teri” (照り, literally “shiny” or “glossy”) and not the name of the sweet and savory sauce. Teriyaki is made by cooking a protein 70-80% through, then basting in a mixture of sake, mirin, soy sauce and sugar. In Kansai, it can be referred to as Tsukeyaki (付焼き).

Yuanyaki is a technique where fish is marinated in a Yuan base containing sake, soy sauce, and yuzu slices (or other citrus fruits). White miso can be added for a flavor boost. This marinade is commonly used for white fish such as Spanish mackerel (鰆), butterfish (真名鰹), and sea bream (鯛), although it can also be used for oily fish and chicken.
A common method of grilling is to thread food on metal or bamboo skewers. However, in traditional Japanese cooking, grilling large hunks of meat, whole legs of lamb or spit roast cooking is non-existential. Instead, the foods are cut into manageable sizes for easy handling and eating. Bamboo skewers are usually used for chicken, tofu and vegetables, whereas stainless steel skewers are used for whole or fillets of fish.
In Japanese cooking, skewering is an art form, as the final presentation is key. Not only is efficient cooking important so that the skewered food is cooked through on all sides, but it must also look appetizing.
Fish is the most difficult as the skin is extremely delicate and shrinks immediately when exposed to heat, hence ruin the shape. If not tended carefully, the fins and tails also scorch easily.
For that reason, the Japanese developed a method of skewering whole fish such as sea bream called Uneri-gushi/Odori-gushi (うねり串・おどり串, “wave skewering,” “dance skewering”) to look as if the fish are still swimming. And smaller fish are skewered together in parallel or spread out like a fan for even cooking.

3. Musu (蒸す) “Steam”
Placing ingredients in a tightly closed pot and cooking them in steam preserves the subtle flavors, aroma, and nutrients for tender and moist results. In professional settings, the common steamers are made of wood or metal, which resemble stacked boxes. In home kitchens, circular Chinese-style steamers set over a wok or improvised steamers in pots are used.
The most important rule is to heat up the steamer to create plenty of steam. The water must be roaring and emitting enough steam to envelope in hot mist. A cold steamer will cook the foods unevenly and may discolor the surface, resulting in an unappetizing and half-cooked mess. Another thing to note is that steaming is not a long process; with enough steam, the food should quickly cook through. Pierce the foods to check for doneness and avoid overcooking.
The typical proteins suitable for steaming are fish, chicken, fish as well as vegetables. They are usually cooked unseasoned, and served with a dipping sauce or a savory topping. But there are other steamed dishes worth noting.
- Okowa (御強), Sekihan (赤飯)
- Chawanmushi (茶碗蒸し)
Okowa (御強), Sekihan (赤飯)
Both are steamed rice dishes made of glutinous rice AKA mochigome (糯米). They have a characteristic chewy and sweet taste compared to plain white rice, and eaten on festive occasions. Okowa is steamed rice mixed with meat, fish or vegetables. As glutinous rice was a luxury, it was only served at special occasions. Sekihan is a type of Okowa with azuki beans.
The exception to high heat quick cooking is Chawanmushi, Japanese steamed egg custard. These cups are steamed in low heat as high heat will form tiny bubble holes in the custard, destroying the delicate texture and flavor. Chawanmushi are dashi enriched egg concoction containing chicken, shrimp, various seafood and vegetables, which are found by digging into the cups. It can be served piping hot or chilled, and at high end restaurants as well as the home.

4. Ageru (揚げる) – “Fry”
The technique of deep frying is not native to Japan; it was first introduced by the Europeans and Chinese. The classic deep fried Japanese food Tempura (天婦羅) actually originates from the Portuguese in the Muromachi era (1336-1573).
Deep frying may seem simple, but it’s a fine art that requires perfect control of the amount of oil, temperature, and the batter.
While it’s best to savor the full, high-level experience of deep fried food at specialty restaurants, you can still enjoy them at home! It is a skill that most Japanese home cooks embrace wholeheartedly, despite limited kitchen space.

The categories of deep fried foods depend on the type of coating used and are the following:
- Su-age (素揚げ)
- Kara-age (唐揚げ・空揚げ)
- Koromo-age (衣揚げ)
- Katsu (カツ), Furai (フライ)
Su-age (literally “naked frying”) is deep fried foods without being dredged in flour or batter. As the food absorbs oil on direct contact, this technique is not suited for soft or watery foods that will become floppy or splatter in oil.
The best are those that will retain its shape and color even when deep fried, such as small freshwater fish, green beans, and slices of sturdy vegetables such as kabocha, lotus root, daikon, and taro. Proteins such as small fish, shrimp and chicken wing tips can also be su-age.
Kara-age (literally “Chinese frying” or “empty frying”) refers to foods dusted in wheat or rice flour, kuzu starch, cornstarch, or potato starch flour then deep fried. Kara-age include chicken, tofu, flatfish (カレイ), and even vegetables.
Tatsuta-age (竜田揚げ) is similar to kara-age, although the protein is first marinated in a soy sauce-mirin mixture, coated in potato starch, then deep-fried.

Koromo-age (literally “robe frying”) is battered and deep fried foods.
Quality koromo-age is airy, light, and crispy, which is achieved by a loosely mixed and lumpy batter. A smooth pancake-like batter becomes a heavy and thick coat of armor, which masks the flavor of the fried food.
The most iconic batter fried food is Tempura (天麩羅). It’s prepared by deep frying ingredients at a high temperature in large amounts of oil for rapid cooking. Its allure is in its contrast of textures – the crisp outer coating with the tender ingredients within.
In Japan, tempura is typically eaten at specialty restaurants and casual soba and udon shops. But you can easily make tempura at home!

- Kakiage (Mix Vegetable Tempura) (かき揚げ)
- Chikuwa Isobeage (ちくわの磯辺揚げ)
Katsu (カツ) & Furai (フライ)
Katsu refers to meat that’s been dredged in panko (Japanese breadcrumbs) then deep fried. You may already familiar with Tonkatsu (トンカツ), fried pork cutlets. In addition to pork, you can find other variations of Katsu (the Japanese transliteration and shortened name for cutlet (カツレツ)) made with chicken, beef, ham and ground meat.
Seafood and vegetables can also be given the same panko treatment, but are called furai (フライ, transliteration of “fry”).
