1980's Japanese movie (semi-sci-fi?) - Where 5 people were beheaded
 

I remember a Japanese movie from the eighties where 5-6 people had their heads chopped off as punishment at the end and the heads rolled side by side next to each other. Could have been underground or in some sort of a cave. I recall the movie being "other worldly" maybe i.e. not a traditional / samurai movie per say. If anyone knows this would really appreciate it!

I think there's a scene similar to that in Swordsman 2 1992.
