To the right, you can see the sadouguchi door used by the host, a regular sized door, unlike the one used by the guests (nijiriguchi), which is very small, so that the guests crawl on all fours. In front, you can see the tokonoma alcove, which is the most important part of the room, decorated with a calligraphy hanging scroll (kakejiku), or sometimes with ikebana. The guests are seated in order of importance, the most important sitting right next to the tokonoma...
