Sakaki: The Divine Tree of Japanese Shinto Rituals
If you have ever visited a Shinto shrine in Japan, you have likely witnessed a serene atmosphere defined by vermilion gates, stone lanterns, and ancient forests. Among the towering cedars and camphor trees, there is a modest, broadleaf evergreen that holds a spiritual significance surpassing all others: the Sakaki (Cleyera japonica).
While it may look like a simple garden shrub to the untrained eye, the Sakaki is the botanical heart of Shinto rituals. From ground-breaking ceremonies to traditional weddings, this sacred tree acts as a bridge between the physical world and the realm of the Kami (gods). For travelers seeking to understand the soul of Japanese culture, understanding the Sakaki is an essential step.
Origins and Botanical Significance
The Sakaki is a flowering evergreen tree native to Japan, Korea, and China. It belongs to the Theaceae (tea) family and is characterized by its glossy, deep green leaves and small, fragrant white flowers that bloom in early summer.
The word “Sakaki” itself is a subject of linguistic fascination. Many scholars believe the name is derived from “Sakai-ki” (boundary tree). In ancient Japanese belief, trees were often planted to mark the border between the sacred space of a shrine and the profane, everyday world. Others suggest the name comes from “Sakaeru-ki” (prospering tree), referring to its evergreen nature. Unlike deciduous trees that shed their leaves, the Sakaki remains vibrant year-round, symbolizing immortality, vitality, and the enduring presence of the Kami.
In regions of Japan where the true Cleyera japonica does not grow (specifically in cooler northern climates), a substitute evergreen called Hisakaki (Eurya japonica) is often used, demonstrating that the concept of the evergreen offering is more vital than the specific botanical species.
The Legend: Sakaki in Mythology
The sanctity of the Sakaki tree is not merely a custom; it is deeply rooted in Japan’s creation myths. The most famous reference is found in the tale of Amaterasu Omikami, the Sun Goddess.
According to mythology, Amaterasu, angered by the violent behavior of her brother Susanoo, retreated into the Ama-no-Iwato (The Heavenly Rock Cave), plunging the world into eternal darkness. To lure her out, the myriad of gods gathered to perform a ritual. They uprooted a massive Sakaki tree from the mythical Mt. Kagu of Heaven. On its branches, they hung holy magatama beads, a large bronze mirror, and cloth offerings.
This decorated tree played a crucial role in the ritual that piqued Amaterasu’s curiosity, eventually causing her to emerge and restore light to the universe. Because the Sakaki was used as a vessel for these divine offerings in the age of the gods, it established the precedent for its use in human rituals today.
Modern Culture and Ritual Use
In contemporary Japan, the Sakaki is ubiquitous in Shinto practices. Its most common form is the Tamagushi (jewel skewer). A Tamagushi is a sprig of Sakaki with shide (zigzag paper streamers) attached to it using hemp or rice straw.
The Tamagushi Offering
During formal worship inside a shrine’s main hall (Haiden), priests and worshippers offer Tamagushi to the Kami. The ritual involves rotating the branch clockwise so the stem points toward the deity, symbolizing a respectful connection between the human heart and the divine spirit.
Household Worship
Sakaki is not limited to grand shrines. In traditional Japanese homes and businesses, you will often find a Kamidana (god shelf)—a miniature household altar. Fresh Sakaki branches are placed in white porcelain vases on either side of the altar. These must be changed regularly, typically on the 1st and 15th of every month, to ensure the space remains pure and vibrant.
Ceremonial Functions
Beyond daily worship, Sakaki is used in purification rituals (Harae). A priest will wave a wand made of Sakaki wood and paper streamers over people, cars, or land to cleanse them of impurity (kegare). It is also a staple in traditional Shinto weddings, where the couple offers a branch together to solidify their union before the gods.
Traveler’s Tips: Spotting Sakaki in Japan
For cultural travelers, spotting Sakaki adds a layer of depth to shrine visits. Here is how you can engage with this aspect of culture:
- Identify the Tree: Look for trees within the shrine grounds that have a white paper strip (shide) tied around the trunk. This indicates that the specific tree is a Goshinboku (sacred tree), and it is often a Sakaki or a massive Cedar.
- Observe the Offerings: When looking at the altar area of a shrine, notice the vases flanking the central mirror. The green branches inside are Sakaki.
- Respect the Boundaries: If you see a rectangular plot of white gravel with Sakaki planted in the corners or center, this is often a Himorogi—a temporary sacred space for deities. Do not step inside.
- Buying Sakaki: You may see bundles of Sakaki sold in Japanese supermarkets or florists. These are for locals to use in their home altars. While you likely cannot take fresh plants home due to customs regulations, seeing them for sale highlights how integrated Shinto is in daily life.
