Katsuobushi sits with the Japanese dry goods, not the fresh fish counter, so look for a small bag rather than anything chilled.

Which aisle is katsuobushi in?

In a Japanese or Asian grocer it is shelved with dashi ingredients, next to kombu and instant dashi powder. Large supermarkets rarely stock it, so a specialist shop or online order is the practical route.

Where to look

  1. Japanese grocers. Shelved with kombu and dashi powder.
  2. Asian supermarkets. Often carry a general fish flake version, check the label for pure bonito.
  3. Online specialist shops. The most reliable source and usually the widest choice of flake thickness.

Buying it online

Since fresh availability is patchy, online is often the easiest route, and a sealed bag keeps its flavour well until opened.

Frequently asked questions

Can I use instant dashi powder instead?

Yes, it is a fast substitute for a quick stock, though the flavour is less rounded than dashi made from real katsuobushi.

How should katsuobushi be stored?

In a sealed bag in a cool, dark cupboard, and used within a few months of opening for the best flavour.
