Chiyo (千代) combines the Japanese chi (thousand) and yo (generation) — meaning "thousand generations." Evokes longevity and lineage, often used as a blessing of long life.
Chiyo was the birth name of Sayuri in Memoirs of a Geisha. Fukuda Chiyo-ni (1703-1775) was the great Japanese haiku poet.
Chiyo reduces to four — the number of Japanese generations.
