Kodo (incense smelling ceremony) was born by the spirit of Zen. Therefore, it places a high value on etiquette and culture. The origin of Kodo is enjoying the sent itself. In Kodo, smelling the incense isn’t called “smelling.” Instead, it is called “listening” because it is believed that an aromatic tree is a living entity that has a soul. Thus, it has to be revered and handled carefully. One must appreciate the blessings of nature and the earth and listen to what the tree has to say.
Kodo is said to have originated from a sacred tree with sacred smells that drifted to Awaji island. The culture of Kodo is made its way from ancient India via China to Japan with the introduction of Buddhism. It means that Kodo is related closely to Buddhist rituals, and therefore, involves a deep spiritual world. In the Heian period, people in the aristocracy listened to the smell as a form of entertainment in the court, which was separated from religious rituals.
This is how Kodo reached its completion in the Muromachiperiod as an art of extravagant luxury along with Chado, Kado, and Noh. Ieyasu Tokugawa, a shogun in the Edo period, also loved Kodo, and imported many aromatic trees including aloeswood.
