In a Japanese supermarket, you may see サラダ油, キャノーラ油, こめ油 and ごま油 in the same aisle. For everyday cooking, choose by the oil source and flavor you want, then read 原材料名 (ingredients) and the package’s use and storage directions. “Salad oil” does not mean it can only be used cold: suitable salad oils can be used both unheated and for cooking.

Nisshin Oillio’s guide to using different oils states that salad oil can be used for both unheated and heated dishes. J-Oil Mills’ FAQ on salad oil and canola oil explains why “salad oil” is not a single plant ingredient. Read the actual bottle rather than guessing from its front name.
Pick one for the meal you are making
- Everyday stir-frying or a mild dressing: a bottle labeled サラダ油, キャノーラ油 or こめ油 may fit, depending on its stated use. Compare size and ingredients so you can finish it while it still tastes fresh.
- Want a noticeable sesame aroma: look at ごま油 and whether it is roasted. You can use an appropriate product in stir-fries or as a finishing oil; Kadoya’s sesame-oil FAQ confirms its plain sesame oil can be used without heating. Check your specific bottle.
- Have an allergy or want a single source: read 原材料名. A name featuring one oil can still be a blend. Our Japanese food allergen label guide shows where to check ingredient and allergen statements.
- After opening: cap tightly and store according to the package, usually away from heat and light for ordinary cooking oils. Nisshin Oillio explains that exposure to air speeds deterioration after opening. Do not use the printed best-before date as a promise of unchanged quality once opened.
Use it safely at home
Check that the pan and ingredients are not dripping with water before adding them to hot oil. Water in hot oil can cause splattering and burns. Stay by the stove while heating oil and turn off the heat if leaving; see the precautions on Nisshin Oillio’s canola oil product page. Do not pour hot oil into a plastic bottle. Specific heating guidance varies by oil and product, so follow the bottle and your appliance instructions.
If you are reading an unfamiliar package, ask: これは炒め物に使えますか。 Kore wa itamemono ni tsukaemasu ka? — Can I use this for stir-frying? Or 香りの強いごま油はどれですか。 Kaori no tsuyoi goma-abura wa dore desu ka? — Which sesame oil has a stronger aroma?
A frequent misunderstanding
“Salad oil” is not an ingredient name. The front tells you the type of oil product, while the back tells you whether it is made from canola, soybean or a blend.
