Soybean and wheat are written in the parentheses after soy sauce.
Ingredients, one by one
| On the label | Type | Role | Notes |
|---|---|---|---|
| カキエキス（広島県製造）oyster extract | Ingredient | Umami (main ingredient) | A concentrated extract made by simmering oysters. Ingredients are listed in order of weight, so this is the largest one. The official shop says it uses “広島県産の牡蠣エキス100%” (100% oyster extract from Hiroshima Prefecture). This means all of the oyster extract is from Hiroshima; it is not the share of the whole sauce (that share is not published). |
| 糖類（砂糖、水あめ）sugars (sugar, starch syrup) | Ingredient | Sweetness | Sugar and starch syrup (mizuame) are grouped under “糖類” (sugars), with the contents written in the parentheses. |
| しょうゆ（本醸造）soy sauce (honjozo, naturally brewed) | Ingredient | Saltiness and umami | Soy sauce made from soybeans and wheat. “本醸造” (honjozo) means it is made by fermenting and aging with koji mold. |
| 食塩salt | Ingredient | Saltiness | — |
| 有機米酢organic rice vinegar | Ingredient | Sourness | Vinegar made from organically grown rice. |
| でんぷんstarch | Ingredient | Thickening | Starch itself is treated as a food. Some typical oyster sauces are thickened with the additive “増粘剤（加工デンプン）” (thickener (modified starch)); see the comparison below. |
| 酵母エキスyeast extract | Ingredient | Umami | Made by extracting the inside of yeast. It is treated as a food, not a food additive. |
| 酒精distilled alcohol (shusei) | Ingredient | Shelf life | Edible alcohol. It is treated as a food, so it is not in the additives section. |
Not found in the ingredient list
This is not the maker's “not used” claim. These are things often seen in similar products that we checked are not written in this product's ingredient list. Additives carried over from ingredients may not be declared, so this does not mean they are absent (about additives not written on labels).

This is the ingredient list from the official page of S&B Foods (エスビー食品), the seller in Japan (checked 2026-09-30). The red text marks food additives. It is thickened with modified starch, colored with caramel color, and given umami with amino acids.
Good points and concerns
+Good points
- 8 ingredients, all of them foods. 0 food additives listed
- Thickened with starch, and no caramel color for coloring
- The oyster extract is made in Hiroshima (the official shop says “広島県産の牡蠣エキス100%使用”, 100% oyster extract from Hiroshima Prefecture)
−Concerns
- ¥793 for 250 g (about ¥317 per 100 g). On the pricey side for an oyster sauce
- Salt equivalent is 11.7 g per 100 g. About 2.1 g in 1 tablespoon (about 18 g)
- Contains yeast extract (not an additive, but an ingredient that adds umami)
