Guren (紅蓮) is a Japanese word meaning "crimson-colored lotus" commonly encountered in the West when used in an artistic connotation. In Japan, Guren (紅蓮) is "crimson-colored (紅) lotus flower (蓮の花)". It is compared to the color of a flame of a burning fire. In Buddhist terminology, Guren is also an abbreviation for Guren Jigoku (紅蓮地獄), which is the seventh of The Eight Cold Hells. Those who fell here after death, it is said that the skin is torn due to severe cold, and the blood looks like a crimson-colored lotus flower. The 10th century Juichimen Kannon may have had a water jar of Guren in its right hand.
