The Water Margin

Can anyone help me, I'm trying to find any existence of a soundtrack for the 1970s Japanese tv series The Water Margin. I particularly liked the music from it but can find no trace anywhere of any soundtrack, maybe there isn't one or if there was it was only released in Japan in the 1970s? Any information would be greatly appreciated. Andy.
