It shrinks to a corner, and trims tie

[Sumikirikuni Chimi] Mojimon, Kakuji-mon, Tsuno-mon and Sumikiri-kado are also called 'Oshiki,' so for example, in "Shoji Monsho O Kuni Meguri Saigoku hen" written by Kiji NIWA, it is referred to as 'Orishiki ni Chikami Sanmon.' The shape of the shrinkage represents the waves. This design was based on the book and 'Monten' . The Samonji-mon crest on the Orishiki is the crest of Mishima Daimyojin. Sumikiri-kaku is an octagonal crest with a square corner and three letters inside it. In the past, the plates and utensils used for the gods were made of various trees, such as the leaves of Kashiwa, etc., by folding them, but later on, they were called Orishiki (folding tray) after they had broken a single tree of Hinoki (Japanese cypress) and made a Kakubon (square tray). In addition, a stand with a hole is attached to three sides of the tray (called Sanpo), which is still used as a sacred object. If you look directly above this mikata or orishiki, it becomes an octagonal shape, and if you put 'Three' of Mishima Daimyojin Shrine in it, you will see the crest of 'Three' in the corner of the corner. ... The letters in the middle are mostly Chidzimi (three letters of the Chinese character), but there are other characters (Jimon (Shinto crest) written by Kiji NIWA) / This name was derived from 'Monten.' In "Heian Monkan" (The History of the Heian Period), it is referred to as 'Gunki Miki at the corner of the corner.'
