I think the national flower of Japan are Yellow Chrysanthemum and the JapaneseApricot, because of its popularity wise and it is said to be the official flowers of Japan.... I hope you can use this....
Most people would say that the Cherry Blossom(Sakura) is the National Flower of Japan. But the Yellow Chrysanthemum and the Japanese Apricot are actually supposed to be the National Flower(or flowers). The Cherry Blossom(Sakura) is more worldly renown because of its role in Japanese Legends and because of its beauty. But the Chrysanthemum used to be the sign of a great Japanese Emperor.
