Reika is a Japanese given name that is often used for both boys and girls, though it is more commonly seen among females. It's derived from the kanji characters " rei " (伟) meaning "beautiful" or "splendid," and " ka " (加) which means "to add." Thus, Reika can be interpreted as "adding beauty" or "making something more splendid." This name has a graceful and elegant sound to it, reflecting its Japanese origins. It gained popularity in Japan during the latter half of the 20th century but remains relatively rare outside of Japan. In recent years, however, it has started to appear more frequently among baby names in other parts of Asia and even in some Western countries, thanks in part to its appealing sound and meaning.
The name Reika has seen a steady increase in popularity over time, with the highest number of births recorded in recent years.
