Rina has independent roots across cultures: Japanese (莉奈, 凜) — "jasmine" or "dignified"; Italian — diminutive of names ending in -rina; Hebrew (רינה) — "joyous song." Rina Sawayama (born 1990) — Japanese-British singer-songwriter and actress; her 2020 debut album SAWAYAMA was named Rolling Stone's, NME's, and Pitchfork's Album of the Year for 2020 and is credited with broadening the British pop landscape. Rina Yamashina — Japanese rugby player. Rina Kostadinova — Bulgarian harpist. Rina Suzuki — Japanese cellist.
Rina 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 Rina reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
