Sayuri is the heroine of Arthur Golden's Memoirs of a Geisha (1997) and the Rob Marshall film adaptation. Sayuri Yoshinaga (born 1945) is the iconic Japanese actress.
Sayuri 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 Sayuri reduce to 3, The Communicator. This is a traditional interpretive system, not a factual claim about the name.
