The mirrors often have no inscriptions other than four words of good fortune in a four-leaf or four-linked arc pattern on the knob. A mirror with an uchigyo hana design in the collection of Harvard University Art Museums was made in the 7th year of Eihei (64) at a private workshop called Gongsunke.

This mirror has a pattern consisting of eight basic arcs arranged inwardly around a knob at the center of the back of the mirror. However, rare mirrors have been found with 11, 9, 6, and 5 arcs. Officially, these mirrors are called "mirrors with a continuous arc pattern", but in Japan they are called "mirrors with an uchigyo hana design" because the design is compared to petals.
Variations range from palm-sized mirrors to much larger mirrors used in rituals. Mirrors with a bead pattern placed on the knob holder, and mirrors with a straight-arc border with a pattern using straight lines and circles have been found. Some of these mirrors have a variety of images formed between the arcs and the button heads.Шаблон:Citation needed
