1. lattice window; window with a wooden grid
A window fitted with a crisscrossing wooden or bamboo lattice framework. A distinctive feature of traditional Japanese architecture, especially townhouses, tea rooms, and temples, providing ventilation and light while maintaining privacy.
Lattice windows line the old townhouses.
Soft light streams in through the lattice window.
Many buildings with beautiful lattice windows remain in Kyoto's Gion district.

Compound of 格子(こうし) ('lattice; grid framework') and (まど) ('window'). A hallmark of traditional Japanese 町家(まちや) (townhouse) architecture, especially in historic districts of Kyoto, Kanazawa, and other cities that preserve pre-modern streetscapes.

Usage

  • The lattice patterns vary by function and region. In Kyoto, different 格子(こうし) patterns historically indicated the trade practiced inside: fine lattices for fabric merchants, wider ones for sake breweries.
  • Functionally, 格子窓(こうしまど) allow air circulation and diffused light while screening the interior from the street — a balance of openness and privacy characteristic of Japanese spatial design.
  • Still seen in modern Japanese architecture when designers incorporate traditional elements.
