Buying Japanese products: how to choose seasonings, snacks and toiletries without making a mistake

Ordering Japanese products online is easy, but the range varies widely in composition, origin, packaging and use. A striking label doesn’t always tell you enough. A bottle of Japanese soy sauce, for example, may contain wheat; a spicy oil might be mostly oil; and a mochi snack could contain milk or soya.

With these practical checkpoints, you can compare Japanese snacks, Japanese sauces, Japanese ramen, udon noodles and Japanese cosmetics based on information you can check on the label or in the product description.

Common pitfalls with Japanese products

1. The name doesn’t always tell you about the origin

A product labelled “Japanese style” doesn’t have to be made in Japan. For instance, Taokaenoi Crispy Seaweed Japanese Sauce lists Thailand as its country of origin. That doesn’t automatically make it a bad choice, but it is relevant information if you’re specifically looking for products from Japan.

So check:

• Country of origin
• Manufacturer and responsible importer
• Whether “Japanese style” is used instead of “made in Japan”
• Whether the flavour suits the dish you’re buying it for

2. “Soy sauce” doesn’t automatically mean gluten-free

Many Japanese soy sauces contain wheat. This applies to Obento Japanese Style Soy Sauce, Murasaki Soy Sauce and Obento Sushi & Sashimi Soy Sauce, among others. If you need to avoid gluten, it’s wise not to just look at the front of the packaging.

Kikkoman Tamari Gluten Free Soy Sauce is made with soya beans according to the product description and contains no wheat in the listed ingredients. The allergen information does mention soya. Always check the current packaging with every purchase, as labels can change.

3. “Spicy”, “light” or “premium” can mean different things

With Japanese chilli oil, it’s important to look at the ingredients. S&B La-Yu contains sesame oil, maize oil, chilli extract and paprika powder, among other things. Momoya Strong MA-LA Chili Oil also includes garlic, Sichuan pepper, sesame, soya products and chicken stock. These are different flavour profiles and not simply interchangeable products.

Also watch out for allergens. Sesame, soya, wheat and chicken can be relevant for food allergies or a vegetarian diet.

Important specifications to check

Ingredients and allergens

Always read the ingredients list for Japanese products, especially for:

• Japanese soy sauce: check for soya, wheat and salt content.
• Ponzu sauce: Mizkan Yuzu Ponzu contains soya and lists yuzu and citrus components, among others.
• Miso soup: Hikari Enjuku Miso Soup Aburaage contains soya, gluten and wheat. The garnish includes seaweed, fried gluten and dried bonito.
• Japanese ramen: instant products often contain wheat and soya. Ajinomoto Soy Sauce Ramen Cup also mentions possible traces of egg, milk and sesame.
• Mochi: Mochi Creamy Matcha Latte contains milk and soya. Royal Family Mochi Creamy Coconut lists soya as an allergen.

A claim like “suitable for vegetarians” should always be checked against the current ingredients list. Recipes can vary by market or packaging.

Net content and when to use it

A small bottle is handy for trying out a seasoning first, while a larger pack can be more economical for daily use. Examples:

• S&B Japanese Chili Oil: 33 ml, ideal for adding in measured doses.
• Mizkan Yuzu Ponzu: 275 ml, usable as a dip, dressing or marinade.
• Murasaki Soy Sauce: 1 litre, practical for regular cooking, but less suitable if you rarely use soy sauce.
• SONOKO Blended Sesame Oil: 150 ml, with 30% sesame oil and 70% soya oil according to the product information.

With oils, pay attention to the ratio of pure oil to blends. A blended sesame oil can have a milder aroma and a different price per millilitre than pure sesame oil. Also check the storage instructions: some products need to be refrigerated after opening.

Preparation and flavour intensity

Japanese ramen and udon noodles differ in cooking time and texture. Ajinomoto Soy Sauce Ramen Cup is designed for hot water and a quick portion. Hikari Miso Restaurant Style Ramen Shoyu Taste contains separate flavour components and wheat noodles. Yi Wan Wu Dong Stir-Fried Udon comes with sauce, oil and sesame sachets and needs to be boiled and stir-fried.

For a quick lunch, you’d therefore choose a cup or simple sachet. For a more substantial meal, udon noodles with sauce and garnish are more suitable. Check beforehand whether you need a kettle, pan or frying pan.

Frequently asked questions about Japanese products

Where can I buy Japanese products online?

You can compare Japanese products online based on ingredients, allergens, content, preparation method and origin. This applies to Japanese snacks, ramen, sauces, mochi and toiletries. For cosmetics such as Japanese hair care, check whether the product is intended for your hair type and follow the usage and safety instructions on the packaging.

What’s the difference between tamari and regular Japanese soy sauce?

Tamari is generally made from soya beans. Regular Japanese soy sauce often also contains wheat. You need to check the difference per product. Kikkoman Tamari Gluten Free Soy Sauce lists a composition without wheat, while Murasaki Soy Sauce contains both soya and wheat.

How long do Japanese sauces and snacks keep?

Check the best-before date on the packaging and follow the storage instructions. Unopened sauces and dry ramen can usually be stored outside the fridge if the label says so. Mizkan Yuzu Ponzu should be refrigerated after opening according to the product information. Mochi and other snacks should be kept well sealed and sometimes need to be refrigerated after opening.
