Shiso: The Japanese Herb That Changed Modern Perfumery
In the contemporary vocabulary of fresh and green fragrance, shiso holds a position of growing importance. Known in Japanese as シソ (shiso) and botanically as Perilla frutescens, it is a herb central to Japanese and broader East Asian cuisine, used as a garnish for sashimi, a component of pickled preparations, and a flavouring for everything from salads to rice dishes. Its scent is unmistakable: green, crisp, and aromatic, with a prominent anise-like quality and a secondary herbal freshness that is simultaneously cooling and invigorating.
In Western perfumery, shiso arrived relatively recently — principally through the influence of Japanese aesthetic values on the avant-garde perfumery of the 1990s and early 2000s. As perfumers sought increasingly nuanced and precise green notes beyond the classical stalwarts of galbanum and violet leaf, shiso emerged as a natural solution: a green ingredient of extraordinary specificity, capable of evoking a particular kind of precision and freshness that no other material quite replicated.
What Does Shiso Smell Like?
To smell fresh shiso leaves is to encounter one of nature's most articulate olfactory statements. The initial impression is green and slightly astringent, with a clarity that cuts through the air. This is followed almost immediately by a prominent anise facet — not the heavy, syrupy sweetness of star anise, but a lighter, more volatile anisic quality that has an almost aquatic freshness. Beneath these top notes is a warm, slightly spicy herbal character, and in the background, particularly in the red shiso variety, there can be a faintly floral, slightly fermented quality.
Green shiso (aojiso) tends to be lighter, more citrus-tinged, and more straightforwardly herbal. Red shiso (akajiso) is more complex, with a darker, slightly animalic quality and a deeper green note. In perfumery, it is typically green shiso that informs the olfactory interpretation, though the red variety's complexity has attracted certain adventurous perfumers.
The shiso note in fragrance occupies a fascinating position between green, herbal, and spicy categories. It has something of the clarity of bergamot, something of the herbal precision of rosemary, and something of the anisic freshness of tarragon — yet it remains unmistakably itself, a note that is defined by Japanese culture as much as by its chemistry.
Shiso's Place in Japanese Culture and Its Emergence in Perfumery
Shiso has been cultivated in East Asia for over two thousand years, with its earliest documented uses in China, where it was valued for both culinary and medicinal properties. It reached Japan centuries ago and became deeply embedded in Japanese cuisine and culture, with both the leaves and seeds used in cooking, the leaves employed as natural dyes, and the whole plant traditionally associated with health and longevity.
The entry of shiso into Western perfumery coincided with a broader period of fascination with Japanese aesthetics in the luxury industry during the 1990s. Japanese designers, artists, and cultural figures were influential across fashion, architecture, and the arts, and this cultural influence inevitably reached perfumery. Japanese perfumers working within international houses, and Western perfumers seeking genuinely new raw materials, both turned to shiso as a natural candidate for exploration.
The note gained particular prominence with the launch of several influential aquatic and green fragrances in the 1990s that incorporated Japanese botanical notes as a way of articulating a new kind of freshness — crisper and more precise than the classical fougere freshness, with a cultural specificity that felt contemporary and distinctive.
Extraction and Aroma Chemistry
Shiso essential oil is produced by steam distillation of the leaves and flowering tops. The oil is relatively volatile — it is dominated by lighter, faster-evaporating molecules that make it primarily a top and heart note material rather than a base. The primary aroma compound in green shiso is perillaldehyde (also called perillyl aldehyde), a distinctive molecule with an intense, green-herbal character with a pronounced anise-like quality. It is, in fact, one of the most powerful natural aroma compounds known, active at extremely low concentrations and capable of characterising an entire composition when used judiciously.
Alongside perillaldehyde, shiso oil contains limonene (contributing a citrus freshness), beta-caryophyllene (a spicy, slightly woody sesquiterpene also found in many other essential oils), and various additional monoterpenes and sesquiterpenes that contribute to the oil's overall complexity.
In modern perfumery, both the natural oil and synthetic perillaldehyde are used. The synthetic material allows perfumers to deploy the characteristic shiso note with greater precision and consistency, adjusting the concentration and combination with other materials to achieve a specific effect. Given the volatility of the natural oil and the intensity of perillaldehyde, shiso is a note that requires considerable expertise to use effectively — a little creates freshness and character; too much can dominate an entire composition in a way that few other ingredients can match.
Famous Fragrances Featuring Shiso
Shiso appears prominently in a number of significant fragrances, though — like many niche or specialist raw materials — it is not always flagged in marketing materials with the same prominence as more familiar notes. Issey Miyake's L'Eau d'Issey, the landmark 1992 fragrance that effectively defined the clean aquatic genre, uses a shiso-adjacent herbal freshness as part of its extraordinary clean, watery opening. The influence of Japanese botanical materials on this fragrance is palpable, and shiso's precision is part of the reason the opening smells so unlike anything that came before it.
Comme des Garçons, the Japanese fashion house with an extraordinarily influential fragrance line, has explored shiso and related Japanese botanicals across several of its avant-garde compositions. The house's commitment to olfactory precision and its willingness to work with unusual raw materials has made it one of the most important laboratories for shiso's development as a fragrance note.
More recently, various contemporary niche perfumers — particularly those with an interest in Japanese aesthetics or molecular precision — have used shiso as a featured note in compositions that celebrate a new kind of green freshness, one that is more focused and specific than the broader green notes of the classical tradition.
Note Interactions: Shiso's Best Companions in Fragrance
Shiso's precision makes it a demanding note to partner effectively, but its range of successful combinations is broader than might initially be expected. Its most natural companions are other clean, fresh materials: citrus top notes — particularly yuzu, bergamot, and green citrus varieties — align beautifully with shiso's anisic freshness, creating opening accords of exceptional clarity and cultural specificity. The yuzu-shiso combination in particular has become a signature of a certain kind of Japanese-inspired fresh perfumery.
With ginger, shiso takes on a slightly spicier, more vivid quality — a combination that works particularly well in masculine and unisex compositions with an outdoor, active character. With aquatic materials and marine notes, shiso enhances the freshness and adds a botanical precision that prevents the aquatic genre from feeling generic. And with green tea — another East Asian botanical — shiso creates a distinctly cultural accord that evokes specific aspects of Japanese food and drink culture with remarkable accuracy.
More surprising perhaps is shiso's ability to work with warmer, more resinous materials at the base of a composition. When used as a top note over an amber or wood base, shiso's freshness creates a compelling contrast — the herbal precision of the opening giving way to the warmth of the base in a way that feels natural and satisfying. This kind of bright-opening-to-warm-base structure is one of the most effective in contemporary fragrance design, and shiso is an ideal top note for it.
Shiso in the Fragrance Wardrobe
Shiso-forward fragrances are quintessentially warm-weather compositions, most at home in spring and summer when their freshness and herbal vitality can be fully appreciated. They project a sense of precision and intelligence — these are not casual, comfort-seeking fragrances but rather compositions that reward close attention and that communicate a specific aesthetic sensibility.
For those interested in exploring beyond the familiar register of mainstream fresh and aromatic fragrances, shiso compositions offer a genuinely distinctive experience. They are an excellent entry point into the broader world of niche fragrance, which has always been more willing than the mainstream to work with unusual botanical materials and to celebrate specificity over universal appeal. Wearing a shiso-based fragrance is a statement not just about scent but about a particular relationship with culture, nature, and the craft of perfumery.
