I've found these words and wonder if anyone can tell me where I might find the tune. It is described as a Japanese song.

Rising, rising is the moon,
Large & round, large & round, round round one,
Plate-like full moon will rise soon.

Hiding, hiding is the moon,
Behind the clouds, dark clouds, black black clouds,
Plate-like full moon will hide soon.

Appearing, reappearing is the moon,
Large & round, large & round, round round one,
Plate-like full moon will rise soon.

I came across it while looking something else up in Google. I don't have a book source for it, only some mentions of it on the web.
