How do say sing in Japanese?
1) 鳴く (na ku) is Japanese 'to sing' when speaking about birds or 'to howl, bark, etc' for other animals; not to be mistaken with a hononym 泣く (na ku) which means 'to cry, to weep'.2) When speaking about people, 唄う (u ta u) (u reads 'oo' not 'yu') is the Japanese word for 'to sing'.If you mean imperative sense of it like asking or commanding to sing for 1) --> 'nake' (na ke) and for 2) --> utae (u ta e) is informal way to say 'sing!'. You can add 'nasai' to end of each of the aforementioned to make it sound formal, polite.
