Does anyone know of a song that in its native language is called "hitori"? It's of Japanese descent but I can't find it. I tried to google some of the translated phrases I remember but only this came up. Here are some of the phrases:

"there by the river sits a pretty maiden
watching the water move along
each gentle breeze that sighs through the cherry trees
echos a song that fills her heart.

Someday I will go to my home that I love so,
once more I will be 'neath the cherry tree,
(this isn't the exact spell but I will do my best:)
hitori de sabi-she furotori de ma-ei rema-sho,
Now as the moonlight dances on the river
sadly the maiden must depart.

That's all I remember but I really want to find it. Can anyone help me?
