Does anyone know what is the name of this Japanese song? (I think it's Japanese)?

I heard the word hallelujah in the song (it sounds like hallelujah) and I think the rest of the lyrics is in Japanese. I heard something like ba la la la la la la la la la la. Each "la" has a higher tone. The song sounds really calm and relaxing. It is sang by a woman vocal. Hallelujah...roku..yi ja....<--when I sing it out, it sounds something like this. I am in desperate need to find his song back. I heard this song 5 years ago. Thank you!

Sorry but it is hard to recognize the word from a single word. Do you remember some more words from it?
