Pleasure quarter usage
Refers to the walled entertainment districts of the Edo period (1603-1868) where licensed prostitution operated. The most famous was 吉原 in Edo (modern Tokyo). These districts developed rich cultural traditions including distinctive speech patterns (廓言葉), fashion, music, and art that influenced Japanese literature and kabuki theater.
Castle usage
In castle architecture, 廓 (or 曲輪) refers to the enclosed areas within a castle's defensive walls. Castles typically had multiple 廓: the 本丸 (main compound), 二の丸 (second compound), and 三の丸 (third compound).
