All about Japanese Cedar (Cryptomeria japonica) essential oil

Origin and nature

Japanese cedar cryptomeria japonica essential oilCryptomeria japonica, also known as Japanese Cedar, stands majestically as a pillar of Japan’s flora. This unique species has graced the landscapes of Japan for millennia. While it is termed ‘cedar,’ this is a misnomer as it belongs to the cypress family. Native to Japan and valued for its wood and aesthetic appeal, it has also found its place in the realm of essential oils.

About the plant

This coniferous tree towers with a grandeur that can reach heights of 50 meters. Japanese Cedar is easily identified by its pyramid shape and a trunk that expands at the base. Its leaves, delicate and spirally arranged, emit a distinctive fragrance when crushed—a hint at the aromatic oil it harbours.

There is little variation in the species of Cryptomeria japonica when it comes to essential oil production. However, there are various types, some with notable differences in size, needle colour, and growth habit. This differences do not significantly alter the chemical composition of the oil extracted. Thus, for our aromatic purposes, we look at the species as a whole.

This ancient tree is entwined with the cultural tapestry of Japan. It is often planted around temples and gardens. Its story begins in the Jomon period, where evidence suggests it was used for building due to its resistance to rot. Fast forward to the present day, and we see the Japanese Cedar still stands as a symbol of endurance and sacredness in Japanese culture.

Cryptomeria japonica has been introduced to various parts of the world. In the United Kingdom, it was first documented in 1842. It has since been a feature in many botanical gardens and parks. The essential oil of Japanese Cedar is not as widespread as other coniferous oils like pine or spruce. However, its unique scent profile is loved by aromatherapists, who seek a connection to the serenity of Japanese forests.

As we look deeper into this evergreen giant’s story, we find that it’s not just the tree that is steeped in history, but also the oil. In ancient times, the wood was burned in religious ceremonies, its smoke carrying prayers to the heavens. Today, the essential oil distilled from the wood and leaves is finding its place in modern aromatherapy. Its essential oil is less flamboyant than some of its botanical cousins, but it still holds a quiet power in its subtle, earthy notes.

Cultural significance and historical tapestry

Japanese Cedar stands as not just a botanical wonder but as a pillar of tradition and spirituality in Japanese culture. Its towering presence and longevity have made it a natural emblem of strength and eternity. It is a living monument that has witnessed the unfolding of Japan’s rich history.

The tree of temples and legends

In Japan, this evergreen is often referred to as “Sugi,”. It occupies a sacred niche, especially within Shinto, the indigenous spirituality of the country. Ancient Shinto practices regard natural elements like trees as abodes for “kami,” or spirits. In this way, the Japanese Cedar is considered particularly sacred. You’ll find these trees surrounding Shinto shrines, where they serve as a bridge between the earthly and the divine.

Historically, the wood of Cryptomeria japonica was—and still is—highly prized. Its resistance to water and decay made it the material of choice for building ships and temples, some of which stand resilient to this day. The Toshogu Shrine in Nikko and many structures in Ise Jingu, the paramount Shinto shrine, are examples of Sugi wood’s enduring legacy.

Interesting facts

  • Japanese Cedar is Japan’s national tree and has been cultivated there for over 2,000 years.
  • The tree’s pollen is a major cause of hay fever in Japan, leading to an annual phenomenon known as “Sugi Cedar Pollinosis.”
  • The largest of its kind, the Jomon Sugi on Yakushima Island, is estimated to be up to 7,000 years old, making it one of the oldest trees in the world.

From wood to oil: historical uses

The transition from wood to oil has historical roots as well. Japanese Cedarwood chips were a valuable export commodity during the Edo period, often used in the production of incense. Its oil was not only a by-product of these processes but also a way in which the wood’s qualities could be preserved and used in various practices.

In traditional medicine, the oil was considered to imbibe therapeutic properties. It found use in soothing the respiratory system and promoting respiratory health. The soothing scent was also believed to bring tranquility. It was used in “Kodo,” the Japanese art of incense appreciation, which has been a cherished cultural activity for centuries.

Today, Japanese Cedar essential oil continues to be valued for its aromatic profile. It lends itself to uses in modern aromatherapy that echo its historical applications. It promotes relaxation, mental clarity, and grounding.


To truly appreciate this oil, one must look at the molecular symphony that occurs within each drop. Japanese Cedar essential oil is a blend of volatile compounds that contribute to its aroma and therapeutic uses. These chemical constituents give the oil its characteristic properties. Understanding them can enhance our appreciation and application of the oil.

The most abundant compounds in Japanese Cedar essential oil include:


Known for their calming properties, these molecules are the foundation of the oil’s earthy and grounding aroma. They include cedrene and cadinene, which offer a hint of spice and woodiness to the scent profile.


Diterpenes like cryptomeridiol and ferruginol are unique to coniferous oils. They are less common in essential oils but provide Japanese Cedar with potent calming and protective properties.


These contribute to the oil’s refreshing and clear scent. α-pinene and limonene offer respiratory benefits and a bright, invigorating aroma.


Although present in smaller amounts, compounds like thymol imbue the oil with a sweet, slightly medicinal note. They are appreciated for their strong protective qualities.

Each compound within Japanese Cedar essential oil plays a role in its holistic effects. The sesquiterpenes, for example, are often attributed with promoting relaxation and emotional balance. In contrast, the diterpenes contribute to the oil’s robustness and resilience, much like the tree itself.

When combined, these constituents create an oil that is not only fragrant but functional. Its chemistry is the reason Japanese Cedar oil can be both soothing to the mind and beneficial for the skin. It is especially beneficial for skin healing.

The method of extraction also plays a crucial role in the chemical composition of the oil. Careful steam distillation ensures that the delicate balance of volatile compounds is maintained. The use of low temperature and pressure provides an oil that is as close to the natural essence of the tree as possible.

Aroma of Japanese Cedar essential oil

The aroma of Japanese Cedar essential oil is as enigmatic as the mist-shrouded forests of its native land. When the bottle is opened, it releases an fragrance that transports one straight to the heart of a serene Japanese woodland.

The initial impression is an invigorating rush of freshness. The aroma is reminiscent of the clean, crisp air one might encounter on a forest walk at dawn. The top notes are vibrant with a hint of citrus. These are likely attributed to the presence of α-pinene, which imparts a sharp, green scent that awakens the senses.

As the oil settles, the heart notes emerge. A complex tapestry of earthy, woody aromas that ground the mind and body. Here, the sesquiterpenes like cedrene and cadinene come into play. These offer a rich depth that is soothing and subtly spicy, bringing to mind the ancient trees’ enduring strength.

The base notes linger longest, a testimony to the deep, resinous quality of the oil. They are warm and persistent, providing a comforting, balsamic undertone. These notes are the soul of the forest, echoing the silent, sustained growth of the majestic Japanese Cedar.

The oil’s unique aroma profile makes it a favourite for meditation and relaxation. Its diffusion creates an atmosphere that can help to center the thoughts and deepen breathing. It creates a tranquil space for mindfulness or in preparation for restful sleep.

In addition to its inherent beauty, the aroma of Japanese Cedar essential oil can subtly influence the environment. Its fresh and woody scent can purify the air, making it a natural choice for home fragrancing. It harmonizes especially well in spaces that seek to embody peace and simplicity. Here, it aligns well with the minimalist aesthetic often associated with Japanese design.

Cultivation, production and sustainability

The journey of Japanese Cedar essential oil from seedling to bottle is steeped in a commitment to ecological stewardship. It is the perpetuation of traditional practices that honour both the tree and the land it hails from.

Japanese Cedar trees are cultivated with a deep understanding of the balance required between human intervention and nature’s rhythms. In Japan, these trees are often grown in managed forests. Here, they play a significant role in the country’s forestry industry due to their rapid growth and sustainable yield.

Foresters carefully select the location and manage the growth conditions. In this way they ensure that the trees can mature in a way that respects the surrounding ecosystem. The trees prefer moist, well-drained soils. They are tolerant of a range of conditions, although they thrive best in their native settings. Their natural habitat has high humidity and adequate rainfall.


Harvesting Japanese Cedar for essential oil production is a task undertaken with reverence and precision. The process is typically done in the colder months, when the trees are less resinous and the sap is not as active. This timing is crucial as it ensures the highest quality wood and leaves for distillation and reduces the impact on the tree’s health.

Only mature trees are selected for oil production. Those which have reached the end of their growth cycle and are beginning to decline naturally. This approach ensures that each tree has contributed to the forest’s ecology for many years before it is harvested.


The distillation of Japanese Cedar essential oil is an art form in itself, a skill passed down through generations. The traditional steam distillation process is favoured. This allows for the extraction of oil without the use of chemicals. The wood and leaves are carefully chopped and then steam-distilled. Low pressure and temperature processes capture the full spectrum of aromatic compounds.

This method ensures that the essence of the tree is preserved. The resulting oil is true to the plant’s natural aroma and therapeutic properties. It is a slow, meticulous process, but one that is essential to yield an essential oil of the highest quality.


Sustainability is a critical aspect of Japanese Cedar essential oil production. Producers are committed to practices that ensure the longevity of the species and its environment. This includes responsible planting and selective harvesting. Growers adhere to strict regulations that protect the forests. This ensures that the trees remain a renewable resource.

The production of Japanese Cedar essential oil is as much about preserving a cultural heritage as it is about creating a product. It is a holistic process that honours the tree from which it came and the land on which it stood.

Sustainability in the production of Japanese Cedar essential oil goes beyond the immediate concerns of supply and demand. It is about fostering biodiversity, protecting soil health, and ensuring that the forest ecosystems continue to thrive. This approach ensures that the use of Japanese Cedar in aromatherapy is not only a nod to tradition but also a gesture of respect to the earth.
