Toyo is a man of average height and build, with a bald head and closed eyes.
Toyo is very passionate about his udon, being visibly agitated about Tanjiro Kamado discarding his bowl without eating any. However, once Tanjiro returns and orders two bowls that he finishes quickly, Toyo is pleased and thanks him for his business.
As an ordinary human, he doesn't posses any additional powers or abilities.
- Toyo can also make soba as well as udon. He says he will never teach anyone how to make the stock.
