Two images of gods are enshrined in the front. Also, two gods can be translated "Niten." Therefore, the Nitenmon is explained as the "Gate of Two Gods." Those gods are called Jikokuten and Koumokuten, and these are two of Shitennou (The four Deva kings). In addition, this gate also is called Kaminarimon (Gate of Thunder) because image of Raijin (God of thunder) is put on the backside of the gate.

On the backside of the gate, you will find images of the red Raijin and blue Fujin (God of wind). The Raijin's fingers are just three, and each finger expresses past, present and future. On the contrary, the Fujin's fingers are four, and each finger expresses the East, the West, the South and the North. Also, the Raijin and Fujin have on two fingers for the leg. Those two fingers of leg indicate the sky and the ground.
