Japanese cooking has a reputation for being technically demanding — the precision, the specialized ingredients, the unfamiliar techniques. This reputation is exaggerated. Most Japanese home cooking is genuinely simple once you understand its internal logic.
The challenge is not the cooking itself. The challenge is building familiarity with a set of ingredients and techniques that are just unfamiliar, not difficult. This guide is designed to take you from no Japanese cooking experience to a functional Japanese home kitchen in one week.
What Japanese Home Cooking Actually Is
First, what it's not: omakase sushi, elaborate kaiseki multi-course dinners, or technically demanding ramen broth. Those exist in Japanese cuisine, but they're analogous to French haute cuisine — not how Japanese people eat at home.
Japanese home cooking is built around a structure called ichiju sansai (one soup, three sides), with a core pantry of 8-10 ingredients that appear across hundreds of dishes, and a set of techniques that are simple but require some practice.
The pantry does most of the work. Once you have dashi, miso, soy sauce, mirin, and sake — the five foundational ingredients — you can cook the majority of Japanese home dishes.
Week 1: The Pantry You Need
Buy these in week one. Nothing else yet.
1. Dashi powder (出汁パウダー)
- Buy: Ajinomoto Hon Dashi (¥/$ equivalent ~$5 for 2.1oz)
- What it is: Instant dashi — dried bonito and kombu essence
- What it does: Provides the base umami broth for everything — miso soup, simmered dishes, sauces
- Use it: Dissolve 1 teaspoon per cup of hot water
2. Miso (味噌)
- Buy: Shiro miso (white miso) first — mild and versatile. Hikari brand or Marukome.
- What it is: Fermented soybean paste
- What it does: Flavor base for miso soup; marinade component; adds depth to sauces
- Use it: 1 tablespoon dissolved in dashi per person for miso soup
3. Soy sauce (醤油)
- Buy: Kikkoman regular (koikuchi/dark soy sauce)
- What it is: Fermented soybean and wheat sauce
- What it does: Seasoning for almost everything — marinades, dipping sauces, finishing
- Use it: In place of salt in Japanese preparations; for dipping gyoza; in teriyaki
4. Mirin (みりん)
- Buy: Hon-mirin (real mirin with 14% alcohol content — Takara brand, or Kikkoman's non-alcoholic substitute works for beginners)
- What it is: Sweet rice wine used for cooking
- What it does: Adds sweetness and gloss to glazes; softens the sharpness of soy sauce
- Use it: In teriyaki sauce (equal parts soy sauce + mirin), in nimono simmering liquid
5. Sake (sake rice wine)
- Buy: Any inexpensive drinkable sake for cooking — Gekkeikan, Ozeki
- What it is: Fermented rice wine
- What it does: Deglazes pans; tenderizes protein in marinades; reduces alcoholic sharpness in sauces
- Use it: In any marinade alongside soy sauce and mirin
6. Japanese short-grain rice
- Buy: Nishiki, Tamaki Gold, or any Koshihikari/Calrose variety
- Ratio: 1:1.1 rice to water, rest 10 minutes after cooking
These six items + rice unlock roughly 80% of Japanese home cooking.
The Five Techniques You Need First
Technique 1: Making Dashi (10 minutes)
Even though you bought dashi powder, learn the instant version first, then the real version when you're comfortable.
Instant dashi: 1 teaspoon Hon Dashi powder per 250ml water. Hot water. Done. Use for miso soup base.
Real dashi (ichiban dashi): Soak 10g kombu in 1 liter cold water for 30-60 minutes. Heat to just below boiling (around 60°C/140°F) over 15-20 minutes. Remove kombu just before boiling. Bring to a boil. Add 20g katsuobushi (bonito flakes). Remove from heat immediately. Steep 5 minutes. Strain. This is the dashi that is the foundation of Japanese cuisine.
Practice: Make dashi once with instant powder, once real. Use for miso soup.
Technique 2: Miso Soup (10 minutes)
The single most practical Japanese cooking skill.
Method:
- Make dashi (250ml per person with instant powder)
- Heat to just below boiling
- Add your filler ingredients (tofu cubed, dried wakame seaweed rehydrated in water, sliced mushrooms — choose one or two)
- Simmer 1-2 minutes until ingredients are warmed through
- Remove from heat
- Dissolve 1 tablespoon miso per person through a strainer into the soup (never boil miso — it kills the flavor)
- Add sliced green onion
Practice: Make this every day for a week. Change the filler ingredients each day (tofu, clam, mushroom, potato, daikon). It takes 10 minutes maximum.
Technique 3: Teriyaki (15 minutes)
The most universally applicable Japanese home technique.
Teriyaki ratio: Equal parts soy sauce and mirin. For one piece of chicken or fish, use 1.5 tablespoons each.
Method for chicken thighs:
- Pat chicken dry. Season lightly with salt.
- Heat neutral oil in a skillet over medium-high heat.
- Place chicken skin-side down. Cook 4-5 minutes until golden brown.
- Flip. Cook 3-4 minutes.
- Add combined soy sauce + mirin to pan.
- Reduce heat to medium. Spoon sauce over chicken repeatedly as it reduces.
- Cook until sauce is glossy and coats the chicken — 2-3 minutes.
The glaze should be shiny (teri means gloss). This same ratio works for salmon, tofu, pork.
Technique 4: Rice Washing and Steaming (5 minutes active + 25 passive)
Japanese rice requires washing before cooking.
Washing: Place rice in a bowl. Cover with cold water. Swirl with your hand. Pour off the milky water. Repeat 3-4 times until water runs mostly clear. This removes excess surface starch that makes rice sticky and gummy.
Stovetop method:
- Washed rice to pot. Add water: 1:1.1 rice-to-water ratio.
- Bring to a boil over high heat with lid on.
- Reduce to lowest possible heat. Cook 12-13 minutes.
- Remove from heat entirely. Let steam with lid on for 10 minutes.
- Uncover and fold rice gently with a rice paddle.
Technique 5: Sesame Dressing — Goma Ae (10 minutes)
A fundamental secondary side dish applicable to any blanched vegetable.
Method:
- Grind 3 tablespoons white sesame seeds in a suribachi mortar (or food processor) until mostly smooth.
- Add 1 tablespoon soy sauce + 1 teaspoon mirin + 1 teaspoon sugar.
- Mix until combined.
- Blanch spinach, green beans, broccolini, or any vegetable in salted boiling water 1-2 minutes.
- Drain. Press out excess water firmly.
- Toss with sesame dressing.
This dressing can go on almost any vegetable. Make extra — it keeps refrigerated 4-5 days.
Week 1 Cooking Plan
Day 1: Make miso soup (tofu + wakame). Cook steamed rice. Eat them together.
Day 2: Teriyaki chicken thighs + steamed rice + miso soup (daikon + aburaage).
Day 3: Make goma ae spinach. Cook rice. Make miso soup (mushroom). Eat all three components together as a proper ichiju sansai.
Day 4: Teriyaki salmon. Rice. Miso soup (clam or potato). Cucumber sliced thin with rice vinegar + salt as a quick side.
Day 5: Hard-boiled egg with soy sauce, sesame oil, and green onion. Rice. Miso soup (any). Spinach goma ae (made Day 3, finish the batch).
Day 6: Freestyle with what you have. Apply teriyaki to any protein. Apply miso soup to any vegetables. Serve with rice.
Day 7: Assess what you're comfortable with. Identify what you want to add next week (karaage? tamagoyaki? nimono?).
What Comes in Week 2
Once you're comfortable with the five core techniques, add these:
- Karaage (Japanese fried chicken): Marinate in soy sauce, sake, garlic, and ginger for 2+ hours; coat in potato starch; double-fry.
- Tamagoyaki (rolled omelet): Requires a rectangular pan. Practice-intensive but satisfying once learned.
- Simmered vegetables (nimono): Kabocha squash, daikon, or root vegetables simmered in dashi + soy sauce + mirin until tender.
- Making real dashi: Upgrade from instant powder once you've used the base techniques comfortably.
Japanese cooking builds in layers. The pantry and the structure come first; the individual techniques accumulate over weeks and months. There's no shortcut around building familiarity — but once the first five techniques are comfortable, the rest of Japanese home cooking opens logically.
