japanese basil
C1specialist (culinary, horticultural)
Definition
Meaning
A culinary herb, typically Perilla frutescens var. crispa, with distinctive purple or green, often ruffled leaves, native to East Asia and used extensively in Japanese, Korean, and Southeast Asian cuisine.
Commonly known as shiso, this herb has a unique flavor profile—a blend of mint, anise, and cinnamon with a slightly peppery note. It is used fresh as a garnish, in salads, sushi, and as a wrap for meats, and dried as a seasoning. Beyond culinary uses, it has traditional medicinal applications in its native regions.
Linguistics
Semantic Notes
"Japanese basil" is a common English name for the plant, but it is not a true basil (genus Ocimum). Using the term can cause confusion with other Asian basils like Thai basil (Ocimum basilicum var. thyrsiflora). The more precise and common term in culinary contexts is "shiso."
Dialectal Variation

Connotations
In both regions, the term primarily evokes culinary, gourmet, or ethnic food contexts. It may be perceived as more technical or specific than simply "basil."
Frequency
Low frequency in general discourse. Slightly higher frequency in contexts related to cooking, gardening, or Asian culture. No significant regional variation in frequency.

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'японский базилик' in precise contexts where 'сисо' or 'перилла' is more accurate.
- Do not confuse with 'базилик обыкновенный' (sweet basil) or 'тайский базилик' (Thai basil), which are different plants.
Common Mistakes
- Using 'Japanese basil' interchangeably with 'Thai basil' (a different species).
- Pronouncing 'basil' in the compound with the American /beɪ-/ when using a British accent, or vice-versa, creating a mixed accent effect.
- Overcapitalising: 'Japanese Basil' is only capitalised at the start of a sentence or in titles.

FAQ
Frequently Asked Questions
Yes, 'Japanese basil' is a common English name for the herb known as shiso (Perilla frutescens var. crispa).
Not directly. Their flavours are distinct. Shiso/Japanese basil has minty, anise-like notes, while sweet basil is more peppery and clove-like. The substitution will significantly alter the dish's character.
Look in Asian grocery stores, specialist greengrocers, or well-stocked supermarkets with an international produce section. It is also easy to grow from seed in warm conditions.
This old-fashioned name refers to the purple-red variety, whose leaf colour was thought to resemble a raw beefsteak. It is less common today to avoid confusion.
