Build Your Japanese Pantry Once, Cook Forever
One of the biggest hurdles to Japanese home cooking is feeling like you need a hundred specialist ingredients. In reality, a well-stocked Japanese pantry comes down to about ten key items. Once these are in your cupboard, you can make the majority of everyday Japanese dishes — and your cooking will improve across the board.
The Essential Ten
1. Soy Sauce (Shoyu)
The most versatile ingredient in Japanese cooking. Use it for marinades, dipping sauces, soups, stir-fries, and seasoning. Start with a good all-purpose koikuchi shoyu (dark soy sauce). A bottle of usukuchi (light soy sauce) is worth having too — it's saltier but lighter in colour, ideal for dishes where you don't want to stain ingredients brown.
2. Mirin
A sweet rice wine used for cooking — not drinking. Mirin adds a gentle sweetness, a subtle sheen to glazes, and helps balance salty soy sauce. Look for hon mirin (true mirin) rather than mirin-style seasoning, which contains added sugar and less alcohol. The difference in flavour is noticeable.
3. Sake (Cooking Sake)
Japanese rice wine serves as both a tenderiser and a flavour brightener. A splash of sake in simmered dishes removes fishy or gamey odours and adds depth. Cooking sake (ryorishu) is more affordable than drinking sake and works perfectly well in recipes.
4. Miso Paste
Fermented soybean paste that adds deep umami to soups, marinades, dressings, and glazes. Keep both a white miso (mild, sweet) and a red miso (bold, earthy) for flexibility. Store in the refrigerator after opening — it keeps for months.
5. Dashi (Stock or Instant)
The foundational broth of Japanese cooking. Homemade from kombu and katsuobushi is ideal, but good-quality instant dashi granules (dashi no moto) are a practical everyday option. Used in miso soup, noodle broths, simmered dishes, and more.
6. Rice Vinegar
Milder and slightly sweeter than Western white vinegar. Essential for sushi rice, pickles (tsukemono), ponzu, and light dressings. Don't substitute with regular white vinegar — the sharpness will throw off your dish.
7. Sesame Oil (Toasted)
A finishing oil, not a cooking oil. A few drops of toasted sesame oil added at the end of cooking transforms a dish — adding a nutty, aromatic depth that's unmistakably Japanese (and East Asian more broadly). Essential for gyoza, noodle salads, and stir-fries.
8. Kombu (Dried Kelp)
The core source of umami in Japanese cooking. Even one small piece of kombu simmered in water creates a beautifully flavoured dashi. It can also be used to pickle vegetables quickly or flavour rice during cooking. Store in a cool, dry place.
9. Katsuobushi (Dried Bonito Flakes)
Shaved, smoked, fermented tuna flakes that form the second component of most dashi. They're also used as a topping for dishes like okonomiyaki and takoyaki, and as a seasoning for rice and vegetables. The aroma when added to hot water is one of the most distinctive smells in Japanese cooking.
10. Japanese Short-Grain Rice
Not an afterthought — Japanese rice is the centre of the meal. Short-grain varieties like Koshihikari or Akitakomachi have the right stickiness and sweetness for Japanese cooking. Rinse thoroughly before cooking and use a rice cooker or the absorption method for best results.
