Cycles
- Hanja vs hangul fashion — Visible in dated KOSTAT mixes.
- Rare-character fashion — Then clerks and phones push back.
- Generation-poem revival in diasporas — Grandchildren ask for the chart again.
- Luck-app rebrands — Same numerology, new UI.
- English-name pairing — A stacked-name cycle in cities.
Signals
- Jinmeiyō updates — Legal inventory news.
- KOSTAT annual tables — Fashion, dated.
- Koseki reform news — Japan household law.
