Also known in several variants all with the same title, each originating in a different area of Japan, each quite distinct in character and mood. Nevertheless, they do have one feature in common-the overall melodic curve. This takes the shape of a mountain with the main peak in the middle, i.e. they all start calmly in the lower register and gradually rise up to reach a peak both in pitch and intensity, then descend to a final calm ending.
