Ryōta has a simple haircut and has brown hair. He has arched soft eyebrows and brown eyes. He normally wears the Hidaka University Uniform but leaves it slightly open, revealing a green top. Ryōta is quite muscular but as Mikhail Makarovich would say, "Your muscles aren't my type."
Ryōta is part of the Hidaka University Swimming Team, hence he must be experienced and skillful.
- Ryōta Suzuki's voice actor, Satoshi Inomata, is also the voice actor for Eita Saotome.
