She has long black hair, generally tied into a spiky ponytail that seems to become more flowy and slightly curly at the very bottom, with a large strand hanging on the right side of her face. Her onyx-colored eyes are big yet sharp and paired with short eyebrows usually set in a determined expression.

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, with lower eyelashes being visibly pronounced. Between 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 that is somewhat connotative of a frog. Her hair is a dark sea-green color and is very long, reaching to her hips with the ends tied together at the bottom in a large bow of hair. She has two armpit-length clumps framing her face and shorter bangs between her eyes, some partially swept to each side. Her normal swimming costume is basically a blue br with swimming shorts

Mina is a girl of medium height, set a little more broadly than some of her other female classmates, with, according to her profile, "healthy thighs".

Minoru Mineta once commented that "she's got a super athletic body". Her normal outfit for swimming is a blue bra and swim shorts
