orizama 折狭間

A loophole in a wall *oribei 折塀 that zigzags back and forth like a folding screen *byōbuori 屏風折. The loopholes *sama 狭間 are cut into the wall on the diagonal to match the angle of the wall, and not at the usual ninety degree angle. The outside opening was typically wider than the inside opening, unlike most loopholes which had small outside openings and large inside openings.
