Etymology: Derived from the Japanese word 'ha' (葉) meaning 'leaf' or more commonly 'hara' (原) meaning 'field', but in this case 'Haba' likely comes from 'hapa' in Okinawan dialect meaning 'slope' or 'hillside'; may also be related to 'haba' (幅) meaning 'width' or 'span' in standard Japanese, though as a surname it most frequently refers to geographical features.
