Minju is from the Korean min (민 — smart, quick) + ju (주 — pearl, jewel). Minju has since transitioned to acting — appearing in major Korean dramas including Hierarchy (Netflix 2024); one of the most-celebrated K-pop-to-acting transitions of recent years. Choi Minju — Korean Olympic figure (golf). Princess Minju — modern Korean heritage naming.
Minju 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 Minju reduce to 4, The Builder. This is a traditional interpretive system, not a factual claim about the name.
