Choosing Japanese Snacks: A Practical Guide to Mochi, Matcha and Japanese Cakes

Buying Japanese snacks in the UK might seem straightforward, but the packaging doesn’t always tell the full story. If you rely solely on a catchy flavour name or a picture of matcha, you could end up with a product that doesn’t suit your taste, storage options or dietary needs.

With Japanese snacks, there are three common pitfalls to watch out for:

  • A flavour name doesn’t tell you how much of the ingredient is actually in there. A product labelled “matcha” may contain only a tiny percentage of matcha powder, with the flavour coming from green tea paste or artificial flavourings instead.
  • Mochi and daifuku have different storage requirements. Some Japanese mochi can be kept in a cool, dry place, while others must stay frozen. Storing them incorrectly affects both texture and food safety.
  • “Light”, “soft” or “natural” isn’t a nutritional comparison. Always check the nutritional values, portion size and ingredients list rather than just the front of the packet.

What to Look for in Japanese Snacks

1. Check the Proportion of the Key Flavour Ingredient

For fans of matcha snacks, it’s worth reading the ingredients list. With the Q-Brand Japanese-Style Mochi Green Tea Flavor, the green tea paste makes up 25% of the product according to the product information. The stated matcha powder content is 0.3%. With the Glico Pock tea biscuit – peach & matcha, both matcha powder and peach powder are listed at 1%.

That doesn’t automatically mean a snack is inferior. It does, however, help you manage your expectations. If you’re after a distinct tea flavour, compare:

  • the percentage of matcha powder;
  • the presence of green tea paste;
  • any added flavourings;
  • the combination with other flavours, such as peach or white bean.

With green tea mochi, the filling can also taste sweeter than the tea itself. Matcha naturally has a pronounced, slightly bitter taste, but in mochi it’s often combined with sugar, maltose or bean paste.

2. Look at Texture, Size and Packaging

Mochi is made from glutinous rice flour, giving it an elastic, chewy texture. Dorayaki consists of soft cake halves with a filling. Baumkuchen is built from thin layers of cake and tends to feel lighter and firmer.

For snacking on the go, individually wrapped items are practical. The Q-Brand mochi (210 g) comes individually wrapped and is designed for taking out or sharing. The Atom Japanese Milk Baum Cake and Atom Japanese Banana Baum Cake (both 80 g) are also individually wrapped according to the product description.

Pay attention to portion size too. A small pack is handy for a single serving, but a larger bag can be better value if you’re sharing with others. Compare the price per 100 g, not just the total price.

3. Check Allergens and Storage Advice

EU regulations require major allergens to be clearly listed. Always check the actual packaging, especially if you have allergies or food intolerances. The products mentioned may contain wheat, gluten, eggs, milk, soya, almonds and possible traces of nuts or sesame.

Storage information varies widely:

  • dry mochi and biscuits: usually keep in a cool, dry place away from direct sunlight;
  • cakes: store well sealed to prevent them drying out;
  • chilled Japanese desserts: keep refrigerated at all times;
  • frozen daifuku: keep in the freezer and do not refreeze after thawing.

The KHY Soy Cream Daifuku Matcha must be stored frozen according to the product information. After thawing, it should be kept chilled and eaten within the stated period. Always check the best-before date and usage instructions on the packaging. Any sachet of drying agent or oxygen absorber is not edible and should be removed after opening.
