Fuka is a Japanese given name of uncertain origin, though it's believed to mean 'blossom' or 'blooming flower'. It is predominantly used for females and is considered quite rare outside of Japan. The name is often spelled phonetically as Fuka when used internationally, but its proper kanji characters are Fu (富) and Ka (香), which translate roughly to 'wealth' and 'fragrance', respectively.
"Fuka was a unique name choice in 2015 with only five babies given this name that year."
