Incense Ingredients
Overview of ingredients
Japanese incense is built from a rich variety of natural ingredients, each contributing its own unique scent and character. From precious woods and resins to roots, barks and spices. These materials are carefully selected and blended to create the refined aromas that Japanese incense is known for. While there are countless botanicals and herbs used in different recipes, this guide covers some of the most common ingredients you’ll encounter.
This is a solid starting point for exploring the art behind each stick.
Machilus Thunbergii (Tabu-no-ki)
Tabu-no-ki comes from the bark of the Machilus Thunbergii tree grown in Taiwan, southern China, and Japan. The bark is carefully ground into a fine powder forming a smooth, steady base for incense.
It doesn’t have a strong scent on its own, but it’s essential in helping the other ingredients burn evenly and allowing their fragrances to unfold naturally.
This will form the base for most Japanese incense.
Agarwood (Jin-koh)
Agarwood comes from trees in the Aquilaria family. Its found across parts of Southeast Asia, India and southern China. What makes it different is how it forms. When the tree is affected by natural stress, it begins to produce a resin deep within the wood. Over time as the tree weakens, that resin slowly saturates the main wood .
It’s been valued for centuries, not just in incense but also in traditional medicine.
The scent is rich and layered. Sometimes slightly sweet, other times darker with a bitter edge. It tends to unfold slowly and develops with each burn.
The highest grade is known as Kyara, meaning “precious.” It’s extremely rare with a depth and character that stands apart even from other agarwood.
Sandalwood (Byaku-dan)
Sandalwood comes from a tall evergreen tree grown across India, Indonesia, and parts of Southeast Asia. It’s been used for centuries, showing up in early Sanskrit and Chinese texts and has long been valued for both fragrance and traditional uses.
The highest quality sandalwood is often linked to the Mysore region in southern India, known in Japan as Rozan Byakudan. It’s slower grown, more refined, and carries a smoother scent.
In incense, sandalwood feels warm, soft, and easy to sit with. It forms the base of many blends, giving them body without taking over.
Benzoin (Ansoku-koh)
Benzoin comes from a tall deciduous tree in the Styracaceae family. The resin is collected by carefully carving into the bark and letting the resin ooze out, Its collected after it has dried. It’s naturally sweet giving incense a soft, rounded quality that smooths out sharper or drier notes.
Benzoin isn’t only for incense, it’s also used in toothpaste, cosmetics, and traditional remedies like cough suppressants. There are two main types, Siam Benzoin and Sumatra Benzoin, each with its own subtle character. In incense, it helps carry the fragrance and gives the blend a quiet, lasting presence.
Kyonishiki is a good example of an incense with high benzoin content.
Borneol (Ryu-no)
Borneol comes from the camphor tree, part of the Dipterocarpaceae family. Inside the branches small crystalline grains form naturally, collecting in the gaps of the trunk. These crystals have a fresh, pine like scent that carries well in incense.
Traditionally Borneol has also been used as an insect repellent and preservative. Its effectiveness is so long standing that traces have even been found in the bones of ancient Japanese tombs. Today it can also serve as a natural alternative to mothballs, quietly protecting both spaces and blends while adding a subtle, bright note.
Kaiunkoh has many ingredients but it is also one of the stronger sticks containing borneol.
Cinnamon (Keihi)
Cinnamon comes from the dried bark of a tree in the Lauraceae family. It’s grown across southern China, Vietnam, Sri Lanka, and Indonesia and has been one of the world’s oldest traded spices. It’s even mentioned in the Bible, as well as in ancient Greek and Roman medicinal texts.
Historically cinnamon was used in preservation and mummification, today it finds its way into snacks, curry sauces, soaps, and body care products. In incense it brings a warm woody spice helping to tie together both the softer and stronger elements of a blend.
Horikawa is a good example of an incense with a strong cinnamon scent.
Clove (Cho-ji)
Clove comes from the dried flower buds of tall evergreen trees in the Myrtaceae family, native to the Moluccas and Zanzibar Islands. Its scent is warm, hot, and spicy, strong enough to be instantly recognisable. In incense clove is usually used sparingly, adding depth and a subtle kick that lifts a blend without taking over.
Historically clove was rare and highly valued. It wasn’t just used for fragrance, it was also prized in cooking. When it was brought to Japan many years ago, it was considered so precious that it was stored in the Shōsō-in, the treasury holding the emperor’s ancient treasures.
Enmei brings a good example of clove, its strong and adds a spicy layer.
Frankincense (Nyu-koh)
Frankincense comes from the resin of trees in the Burseraceae family, grown along the coasts of northeast Africa, the Arabian Sea, and Somalia. One of the most prized substances in the ancient world, it has long been used in religious ceremonies and sacred rituals.
Its scent is light, resinous, and slightly citrusy adding brightness to a blend. Beyond incense frankincense has also been valued in traditional herbal remedies, known for its calming and pain relieving properties.
Honoka is a great example of smooth frankincense
Patchouli (Kakkoh)
Patchouli comes from an Asiatic shrub in the shiso family, originally from the Philippine Islands. The leaves produce a warm woodsy fragrance, though young green leaves have little scent. Strength only develops as the leaf matures and moves away from the stem.
Used in Japanese incense for many years patchouli provides a deep, grounding note that forms a subtle base. Its familiar, earthy aroma helps give a blend weight and warmth, quietly supporting the other ingredients.
Although patchouli is quite subtle, you may pick it up in Kasumi.
Star Anise (Dai-uikyo)
Star Anise comes from the ripened fruit of an evergreen tree in the Illiciaceae family, mainly grown in southern China. Once dried the fruit develops a lively, sweet, and herbaceous scent.
It has long been used in both cooking and medicine, a staple in Chinese cuisine and a traditional remedy for digestive issues. In incense star anise adds a sweetness and a subtle herbal lift, giving blends a brightness that complements deeper woodier notes.
Kaden Kobunboku highlights the sweet spice of star anise well.
Misho - Gentle Smile
Built around premium agarwood (aloeswood), Misho blends deep, resonant woods with soft accents of cinnamon, clove, benzoin and camphor. The result is a calming aroma that feels warm, spiced and comforting.
