Yoriichi is a tall man with a muscular build, fair skin, maroon eyes, and long spiky hair with red tips that he kept in a ponytail. He has a similar overall appearance to his twin brother Michikatsu, but unlike him, he was slightly more slender, had shorter bangs, and wavier hair than him. Yoriichi is always seen with an aloof and solemn look on his face, rarely showing emotion. Yoriichi wore a red haori over a very pale orange-colored nagagi kimono with a black umanori-styled hakama.
