Fuji (藤, ふじ) is one of the most famous indigenous flowers in Japan.
The original species can be seen in mountains in Japan, but nowadays we can see them in parks and gardens in cities. When cherry blossoms are gone in April, Fuji flowers open.
The original kanji "藤" in Chinese culture indicates vine plants without flowers, but Japanese culture turns this kanji’s meaning into an indigenous vine-like plant with purple or white flower.
We can find many Japanese people who have kanji "藤" in their surnames.
Their surnames derive from Fujiwara clan (藤原氏) - one of the most influential families in Japanese history. Throughout Japanese history Fujiwara clan bore many famous imperial nobles as well as samurai warlords, that makes contemporary Japanese families have surnames with one of Fujiwara’s kanji "藤".
