With the introduction of Buddhism to Japan in the 6th century, the custom of offering flowers on the Buddhist altar became common. As indicated by the use of the Chinese character meaning "flower" is the names of sutras such as the "Kegon-kyo (Avatamsaka Sutra)" and "Hokke-kyo (Lotus Sutra)," from the beginning flowers have been deeply related to Buddhism. Lotus is widely found in India where Buddhism originated, and it is a representative flower for Buddhist offerings. In Japan, however, other suitable flowers for each season were selected for this purpose. Among various ways of Buddhist offering, placing Mitsugusoku, a set of three ceremonial objects - flower vase, incense burner and candle holder – became popular in the Kamarura and Nanbokucho periods.
