Tani is a unisex given name of Hawaiian origin, meaning 'sacred' or 'holy'. It is often used for both boys and girls, reflecting the cultural harmony and respect for nature that Hawaii is known for.
"Tani appears to have been a popular name from the late 1940s to the early 1960s, with peaks of 35 births in 1962 and 62 in 1963. After this period, its popularity significantly declined, never again reaching double digits until the mid-2000s when it stabilized around 7 births per year."
