Suzu (鈴) is the Japanese word for "bell" — particularly the small bells used in Shinto shrines to call the gods. A modern Japanese feminine name.
Suzu Hirose (born 1998) is the Japanese actress (Our Little Sister).
Suzu 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 Suzu reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
