The burning of incense in Japan began during the 6th century (the Asuka period) with the introduction of Buddhism, which uses incense during rituals and ceremonies. Agarwood was imported into Japan from China via Korea. From that point on, incense would become an important facet of Japanese culture. Incense is used for a variety of purposes, including Buddhist ceremonies, spirituality and meditation. Many of the current incense companies have been in existence for more than 300 years.
