Tsuyu is a short girl of a relatively slender build and has notably large hands. Her appearance is rather frog-like; she has a wide mouth, which dips down a little in the middle just like a common frog, and oval-shaped eyes with large, black irises, their lower eyelashes visibly pronounced. Amongst her family, Tsuyu's frog-like traits are the least pronounced. She also demonstrates some frog-like mannerisms, such as hopping on all fours instead of running and holding herself in a way.
