Chrysanthemum Day (菊の節句 Kiku no Sekku) is celebrated on the 9th day of the 9th month. It was started in 910 A.D. when the Japanese imperial court held its first chrysanthemum show. Chrysanthemums are the symbol of the Imperial House of Japan.

Kasugi Isshō (1652-1688)
My eyes, having seen all,
Came back to
The white chrysanthemum
“If you would be happy for a lifetime, grow chrysanthemums.”
