The door, nijiriguchi, of Taian, is merely a weathered plank. Ironically, one of the smallest existing teahouses has an usually large nijiriguchi. The large door, 78.8cm by 71.5cm, allows the guest to crawl through to the tearoom. Crawling through the door presents the guest as larger than they are. The guest is also shocked at the image of the tokonoma directly in front of them, and a large window directly above them.
