There are two types of Nioson: A-shape and Un-shape.
The one with an open mouth is called A-shape, and the one with a closed mouth is called Un-shape.
A gate with Nioson placed inside is called Niomon, which refers to a gate with Zochoten and Jikokuten, two of the Four Heavenly Kings, placed inside.
It is also said that the opening and closing of the mouth is linked to the opening and closing of the gate, opening the gate to good realms and closing the gate to evil realms.
The A-shape has an open mouth, which represents the letter "a," meaning the beginning of things, and is said to symbolize the beginning of the law.
The Un-shape has a closed mouth, which represents the word "n," meaning the end of all things, and is said to symbolize the end of the law.
