How to choose an I-name

  1. Decide kanji early if the meaning matters legally or culturally.
  2. Check international pronunciation — Ichika vs Itsuki travel differently in English.
  3. Birth-order names like Ichirō carry tradition; use deliberately abroad.
  4. Cross-theme: Izumi pairs with water; Isamu with brave.
