Haruki is from the Japanese haru (春 — spring) + ki (輝 — radiance, brightness). Haruki Nakamura — Japanese paper craft artist. Haruki Yamamoto — Japanese sumo wrestler. Haruki Sato — Japanese baseball player. Haruki is one of the most-popular masculine Japanese names but is also used as a unisex/feminine name in some modern American families given Murakami's global cultural influence.
Haruki does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Haruki reduce to 5, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
