Castles
Lit. "section breaks." A technique used to build a castle wall. Separate sections of the castle wall *hei 塀 were constructed by setting two independent posts into the ground about every 10-*ken 間 (approximate 18.5 m), with their penetrating tie beams *nuki 貫, unconnected. This ensured that even if one section of the wall fell due to enemy attack, only that section of the wall would be affected, and the rest would remain staunchly in place.
