"The cherry blossom is a very delicate flower that blooms for a very short time. For the Japanese this represents the transience of life. This concept ties in very deeply with the fundamental teachings of Buddhism that state all life is suffering and transitory. The Japanese have long held strong to the Buddhist belief of the transitory nature of life and it is very noble to not get too attached to a particular outcome or not become emotional because it will all pass in time.
The fallen cherry blossom is not taken lightly in Japanese symbolism either. It often represents the beauty of snow and there are many connections made in Japanese literature or poetry to a fallen cherry blossom and snow. This also has been extended to the life of a warrior whose life was ended early in battle."
