Gift or great joy
In a Japanese context, the name is often associated with the word for 'diamond' (daiyamondo), though it can be formed from various kanji meaning 'great' combined with 'value' or 'joy'. It also appears as a rare variant in other cultures, sometimes linked to the Hebrew name Daya, meaning a bird of prey, or as a modern rhythmic invention.
About 15 girls were named Daiya in 2025.
