Japanese Folk Metal

For a while I've been searching for japanese folk metal bands, and so far I've only found Omnyo-Za (other asian folk metal bands I've found are Gostwind (Korean, not exactly my style) and ChThonic (Taiwan), which is more like black metal). I want a metal band a-la northern Europe celtic/viking style...except that, instead of having celtic/viking elements, has a japanese traditional music feel. Not like that finnish band Whispered, I want a japanese metal band with folk instruments! Any recommendations? Thanks in advance.

This is one of the best japanese folk metal LOUDNESS

Now that was a great song! Didn't know about that band, pretty awesome. Although they're not quite folk metal, they don't have any japanese folk music feel in their music...still, thanks a lot!
