Joshiro Maruyama (丸山 城志郎, Maruyama Jōshirō; born 11 August 1993) is a Japanese retired judoka. He is famous for his signature uchi-mata technique.
Maruyama won a gold medal at the 2019 World Judo Championships & 2021 World Judo Championships.
Maruyama had a fierce rivalry with fellow Japanese -66 kg competitor, Hifumi Abe. The two fought in a highly anticipated and specially organized match to decide which player would be Japan's representative in the weight category for the Tokyo 2020 Olympics. The match ran almost twenty minutes into golden score, at which point Abe defeated Maruyama with an ouchi-gari, scoring waza-ari and ending the match.
