Meaning & origin

Hiroki is a Japanese masculine name that combines meanings like 'abundant', 'prosperous', or 'broad' with 'joy' or 'tree'. First recorded in the U.S. in 1979, its peak year was 1996, reflecting a wave of interest during the 1990s. Since 1993, its trajectory has been falling, mirroring broader trends in Japanese name usage. While it has never entered the U.S. top 1000, its appearance in the 1990s decade with a falling trajectory suggests a brief period of adoption among families seeking authentic Japanese names, though it remains relatively rare nationwide with no top states recorded. The name's etymological layers and cultural resonance in Japan continue to give it appeal for those with heritage or admiration for Japanese culture.

Hiroki is a Japanese masculine given name composed of two kanji characters. The first element 'hiro' can mean 'abundant' (裕), 'prosperous' (弘), or 'broad' (広), while 'ki' typically means 'tree' (木) or 'joy' (喜). The name has been in use since at least the late 1970s and became moderately popular in Japan during the 1990s.
