Seven ingredients cover roughly 80% of Japanese home cooking flavor work — and they build on each other in a predictable order. Shoyu, mirin, and dashi form the structural trio; miso and sake extend it; rice vinegar and koji handle the advanced work. Build the pantry in this sequence and the cooking follows without chasing individual recipes.
Start here: what's your situation?
- Starting from zero: buy koikuchi shoyu, hon mirin, and dashi ingredients (dried kombu and katsuobushi) first. These three unlock 70% of Japanese home cooking before anything else. → Shoyu, Mirin, Dashi
- Have the basics, want more depth: add white miso and cooking sake. Miso goes into soups, glazes, and marinades immediately. Sake completes the 3:2:1 ratio and handles deglazing and odor suppression. → Miso, Cooking Sake
- Solid core, want to refine: add plain rice vinegar for sushi rice, ponzu, and pickles — then read the fermentation section below for shio koji and koji. → Rice Vinegar
- Ready to ferment actively: start with shio koji (7 days in a glass jar, no special equipment). Once that habit is established, move to dried rice koji for homemade miso. → Shio Koji, Koji

Build the pantry in three tiers
Not all pantry staples are equally urgent. Some appear in nearly every Japanese dish; others matter only when you move into fermentation or want to refine specific results. If you are starting from nothing, this sequence avoids buying things you will not use before you understand what they are for.
- Tier 1 — savory structure (buy first): koikuchi shoyu, hon mirin, dashi ingredients (dried kombu and katsuobushi). Unlocks 80% of Japanese home cooking — stop here if budget is tight. These three appear together in more Japanese dishes than any other combination. Quality matters most here because there is nowhere to hide.
- Tier 2 — depth and seasoning (buy next): white or mixed miso, cooking sake (ryorishu). Completes the 3:2:1 ratio and adds miso's fermented depth — add these once Tier 1 is routine. Miso is immediately useful across soups, glazes, and marinades. Sake handles deglazing, odor suppression, and the third leg of the shoyu–mirin–sake trio.
- Tier 3 — brightness and balance (useful later): plain rice vinegar. Unlocks sushi rice, ponzu, and pickling — add it when those applications come up. Essential for sushi rice, ponzu, pickles, and dressings, but less central to everyday cooking until those applications come up.
- Fermentation add-ons — when you are ready: shio koji (ready-made or home-made from rice koji), then dried rice koji starter if you want to make your own shio koji, amazake, or eventually miso. Not urgent for everyday cooking — start here only when the core pantry is solid. These extend the pantry into active fermentation territory. And for finishing, furikake turns plain rice into a complete bowl with almost no effort.
One ratio unlocks most dishes: 3 : 2 : 1
The combination that runs through most Japanese home cooking is 3 tablespoons shoyu : 2 tablespoons mirin : 1 tablespoon sake. This ratio is the base for teriyaki, yakitori tare, oyakodon, and most nimono braises. Extended with dashi, it becomes a simmered dish broth. Reduced alone, it is a glaze. Combined with miso, it becomes a miso tare. Knowing one ratio and how dashi extends it unlocks more of Japanese cooking than any single recipe collection.
Dashi is what the ratio lives in. To make ichiban dashi: steep a 10 cm piece of kombu in 1 litre of cold water for 30 minutes, then heat slowly to 60–70°C and hold for 20 minutes without boiling. Remove the kombu, raise heat to 80–85°C, add a large handful of katsuobushi, steep for 2 minutes, then strain. The result keeps refrigerated for 3 days and is the liquid base for miso soup, simmered dishes, and noodle broths.

Pantry map: what each ingredient actually does
The ingredients below are not equal in urgency or function. Understanding which group each belongs to makes it easier to see which entity pages are worth reading first and what to buy when. If a dish tastes flat, something from the savory structure group is missing. If it lacks shine or sweetness, the sweetness group. If it is too one-dimensional, the brightness group. This map tells you where to look.
Savory structure: shoyu, miso, dashi
These three provide the glutamate-led umami backbone of Japanese cooking. Most dishes start here. Shoyu seasons and darkens. Miso provides depth, body, and fermented complexity. Dashi — made from kombu and katsuobushi — produces more perceived umami than either ingredient alone, because the glutamates in kombu and the inosinates in bonito synergize. If a dish tastes flat, something from this group is usually missing.
If your question is about depth and saltiness in a dish: → Shoyu, Miso, Dashi
Sweetness and gloss: mirin
Mirin handles natural sweetness, lacquered finish on glazes, and the balance that prevents salty-only results. It is not interchangeable with sugar — the fermentation process adds body and a mild savory depth that sugar cannot replicate. Hon mirin (true fermented mirin, ~14% alcohol) behaves differently from aji mirin (mirin-fu seasoning, glucose-syrup based) in high-heat applications; the difference shows clearly in teriyaki and in tare glazes.
If your question is about sweetness, glaze texture, or whether hon mirin is worth buying: → Mirin, Hon Mirin vs Aji Mirin
Brightness and aroma: rice vinegar, cooking sake
Rice vinegar (4–5% acidity, gentler than Western vinegars) manages acidity without sharpness — essential for sushi rice, tsukemono pickles, and ponzu. Cooking sake contributes alcohol-volatile aromatics, suppresses fishy or gamey odors, and adds mild sweetness and amino acid depth to simmered dishes. Together they handle what shoyu and mirin alone cannot: the acidic and aromatic register.
If your question is about acidity, pickling, or deglaze logic: → Rice Vinegar, Cooking Sake, Sake vs Mirin for Cooking
Fermentation foundation: koji, shio koji
Koji (Aspergillus oryzae) is the enzymatic core behind miso, shoyu, mirin, and sake. Its protease and amylase enzymes break down proteins and starches into the amino acids and sugars that create umami and sweetness in every fermented pantry staple. Shio koji is the most practical daily form for home cooks: rice koji mixed with 10–13% salt by weight, fermented 7 days at room temperature. Use 1 teaspoon per 100 g of protein as a marinade — it tenderizes and seasons with a depth that salt alone does not achieve.
If your question is about the fermentation logic behind these ingredients or how to make shio koji: → Koji, Shio Koji, How to Use Shio Koji, Koji vs Shio Koji
Buy white miso first — it covers every application until you need more
Miso is a fermented paste made from soybeans, salt, and koji culture. It is used in soups, marinades, glazes, salad dressings, and as a finishing seasoning. Its flavor ranges from delicate and sweet in white miso (shiro miso, fermented weeks to 2 months with rice koji) to deeply savory in long-aged red miso (aka miso, 6–24 months). Kyoto-style shiro miso is mild and slightly sweet. Sendai aka miso is robust and funky. A mid-range white or mixed miso covers most everyday use.
For pantry purposes: dissolve miso off the boil, never boil it — high heat kills the active enzymes and flattens the aroma. One tablespoon dissolved in 200 ml dashi is the base for a bowl of miso soup.
If your question is about miso types and how to choose: What Is Miso. If it is about cooking with miso beyond soup: How to Use Miso. If it is about white vs red miso specifically: White Miso vs Red Miso.
Koikuchi shoyu is the all-purpose workhorse — buy this, then specialize
Shoyu is Japanese soy sauce — brewed from whole soybeans, roasted wheat, and salt through fermentation that can last a year or more. The most common type is koikuchi shoyu, a dark all-purpose soy sauce. Key variants: usukuchi (light-colored, saltier, common in Kansai cooking — do not substitute for koikuchi by volume), tamari (wheat-free or low-wheat, richer and thicker, good for dipping), shiro shoyu (very light in color, seasons without darkening a dish). The gap between naturally-brewed artisanal shoyu and industrially produced soy sauce (hydrolyzed protein, added caramel color) is clear in a side-by-side taste.
For most pantry builds: koikuchi shoyu as the all-purpose workhorse. Add usukuchi if you cook Kansai-style simmered dishes where pale color matters. Tamari is worth having once you start dipping and saucing regularly.
If your question is about shoyu types and production: What Is Shoyu. If it is about the practical difference between shoyu and generic soy sauce: Shoyu vs Soy Sauce.
Hon mirin is worth the upgrade — here's why aji mirin falls short in high heat
Mirin is a sweet rice wine used exclusively for cooking. Real mirin — hon mirin — is made by fermenting glutinous rice with koji and blending with shochu, resulting in a liquid with ~14% alcohol, natural sugars, and a subtle savory depth. It gives teriyaki its lacquered shine, balances saltiness in tare, and rounds out simmered dishes. The alcohol also tenderizes proteins and suppresses odors.
The key pantry decision: hon mirin vs aji mirin (mirin-fu seasoning). Aji mirin is glucose syrup with flavor additives — it is cheaper and sweeter but does not behave the same way in high-heat applications where alcohol aroma development matters. For serious pantry work, hon mirin is the correct choice.
If your question is about what mirin is and how it works: What Is Mirin. If it is about whether hon mirin is worth buying: Hon Mirin vs Aji Mirin. If it is about mirin in actual recipes and cooking ratios: How to Use Mirin.
Rice vinegar: add this for sushi rice, pickles, and ponzu (Tier 3, not urgent)
Rice vinegar sits at roughly 4–5% acidity — milder than Western white or cider vinegars. Made by fermenting rice wine into acetic acid, it integrates into dishes rather than standing out as a sour element. Indispensable for sushi rice (seasoned at 1 tablespoon per 180 ml dry rice), ponzu, tsukemono, and dressings. Seasoned rice vinegar has salt and sugar added — convenient for sushi rice but less versatile for general cooking. Plain rice vinegar is the more useful pantry item.
Chinese rice vinegars are different: black vinegar (Chinkiang) has a very different flavor profile and is not interchangeable with Japanese rice vinegar for most applications.
If your question is about rice vinegar types, substitutes, or uses: What Is Rice Vinegar. If it is about ponzu (rice vinegar plus citrus): What Is Ponzu.
Make dashi in 30 minutes: the liquid base every other pantry item lives in
Dashi is the foundational broth — a clear stock made by steeping ingredients to extract umami, not cooking them down for richness. Ichiban dashi: steep a 10 cm piece of kombu in 1 litre cold water for 30 minutes, heat slowly to 60–70°C, hold 20 minutes without boiling, remove kombu; raise to 80–85°C, add a large handful of katsuobushi, steep 2 minutes, strain. The glutamates in kombu plus the inosinates in katsuobushi synergize — combined umami perception is significantly greater than either alone. Keeps refrigerated 3 days.
Good kombu is the foundation of every dashi. Grade matters: premium Ma-kombu or Rishiri-kombu for clear, delicate broths; standard kombu for everyday use. Understanding kombu selection is worth attention before optimizing ratios and technique.
If your question is about dashi types, ratios, and how to make it: What Is Dashi. If it is about kombu selection: What Is Kombu. If it is about how to use dashi in dishes: How to Use Dashi.
Shio koji is the first fermentation project: 7 days in a glass jar, no equipment
Koji is Aspergillus oryzae cultivated on grains — most commonly rice or barley. Its enzymes break down proteins and starches into the amino acids and simple sugars that create umami in miso, flavor complexity in shoyu, and sweetness in sake and mirin. Koji is not used directly in most everyday cooking, but understanding it explains why all the other pantry staples work the way they do.
Shio koji is the practical daily form: rice koji mixed with 10–13% salt by weight, water added to cover, fermented 7 days at room temperature with daily stirring. Use 1 teaspoon per 100 g of chicken, fish, or vegetables as a marinade or seasoning. The protease enzymes begin breaking down surface proteins overnight, developing glutamates and tenderizing texture. Shio koji can be purchased ready-made or made at home in a glass jar with no special equipment.
If your question is about what koji is and how fermentation works: What Is Koji. If it is about shio koji — how to make or use it: What Is Shio Koji and How to Use Shio Koji. If it is about home fermentation more broadly: Fermentation hub.
Cooking sake: complete the 3:2:1 trio and handle every deglaze and odor problem
Cooking sake (ryorishu) is sake formulated for culinary use — often with a small amount of salt added to make it unsaleable as a beverage while reducing cost. It deglazes pans, suppresses fishy and gamey odors through alcohol volatilization, and adds mild sweetness and amino acid depth from rice fermentation. Alongside shoyu and mirin, it forms the standard three-ingredient seasoning trio in teriyaki, simmered dishes, and yakitori tare.
The practical pantry choice: cooking sake covers everyday use well. For delicate applications where the sake flavor is exposed — steamed clams, a finishing splash — quality drinking sake gives a cleaner result. The 3:2:1 ratio (3 tbsp shoyu : 2 tbsp mirin : 1 tbsp sake) is the simplest context in which to learn how sake interacts with the other two.
