nurisashi-mado
A window made by exposing part of the lath for a mud plastered wall, which is made of bamboos or reeds, by being left unfinished. It is often seen in a tea-ceremony structure and Japanese old houses, and Akari-Shoji, made of a wooden frame covered with Japanese washi paper on one side to let more light in, or Kake-Shoji, a hanging translucent Shoji screen, installed on the interior side. As no window frame is used and the opening is formed in a subtractive manner, the shape and/or position can be freely chosen.
