You want to make soup in Japan and find a shelf full of だし. Some packages contain dried fish, some contain kelp, and a packet marked “kombu” may still include other seasonings. To choose one, read the flavor on the front, then check 原材料名 (ingredients) and the directions on the back. The product name alone is not a complete ingredient list.
Dashi words you will see

| いりこ / 煮干し | iriko / niboshi | Dried small fish, commonly sardines. |
| しいたけ / 椎茸 | shiitake | Shiitake mushroom. |
| あわせだし / 合わせだし | awase dashi | Combined stock flavors; check which ingredients are combined. |

Choose the packet in three checks
- Pick the base flavor. かつおだし has bonito, いりこだし uses dried fish, and 昆布だし is kelp flavored. An あわせだし may combine fish and kelp. Yamaki’s dashi product range illustrates these different bases.
- Read 原材料名 and allergy information. A granulated product may contain salt, sugar, soy sauce powder, extracts or other ingredients in addition to the ingredient pictured on the front. For example, Ajinomoto’s bonito stock product lists its full ingredients and milk allergen information. A Shimaya kombu granule product likewise directs customers to check the current package because ingredients can change. If avoiding fish or animal ingredients, confirm every component on the actual pack; “kombu” on the front is not by itself a vegetarian certification.
- Read the amount and method. Granules or powder are usually measured into liquid; a だしパック is steeped and removed according to its instructions. Concentrated liquid stock has its own dilution directions. Use the water quantity and amount printed on your product rather than borrowing a ratio from a different brand.
At home: a simple soup decision
For miso soup, prepare the vegetables and stock according to the ingredients and packet directions. Add miso and taste before adding more salt or stock powder. A tub labeled だし入り already includes dashi ingredients, so check it before doubling up; see our guide to Japanese miso labels. If you need to avoid a specific ingredient, our food allergen label guide explains the relevant package sections.
You can ask a shop worker: 魚が入っていないだしはありますか。 Sakana ga haitte inai dashi wa arimasu ka? — Do you have a dashi without fish? Or このだしは何ミリリットルの水に使いますか。 Kono dashi wa nan-miririttoru no mizu ni tsukaimasu ka? — How much water is this dashi for?
Common mix-ups
“Natural” or “kombu” does not tell you the whole recipe. A flavor name identifies a feature of a product, while the ingredient list tells you what is actually included. A Yamaki bonito-and-kombu granule, for example, lists salt, glucose, fish and kelp ingredients. Compare products by the actual labels if sodium or diet restrictions matter.
Salt equivalent is tied to a stated serving basis. Check whether the number is per 100 g, per packet or per serving before comparing two brands. Recipes and packaging change; the pack in your hand is the final reference for ingredients, preparation and storage.
