Hideki is a masculine given name of Japanese origin, derived from the elements "hide" meaning "generous" and "ki" meaning " tree". It is often used by parents hoping their child will grow up to be as steadfast and strong as an ancient oak tree. The name Hideki gained popularity in Japan during the post-World War II era, and has since been adopted globally, particularly among Japanese communities abroad.
Hideki experienced peak popularity in 1974 with 9 births that year. It then fluctuated, reaching another high of 7 births in 1981 before declining to 5 births in 1982. Over the four years, a total of 27 babies were named Hideki.
