Amaya has multiple origins. In Japanese (雨夜), it means "night rain" — a poetic image. In Basque (Amaia), it means "end" or "final." Both pronunciations have braided in modern English use.
Amaya entered the U.S. top 1000 in 1999 and has been rising. Today it sits in the U.S. top 250. The convergence of two beautiful etymologies in one soft three-syllable name has helped its rise.
Amaya 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 Amaya reduce to 5, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
