Shionoumi Unemon (born Tado Kishimoto; 1 March 1918 – 18 July 1983) was a sumo wrestler from Himeji, Japan.

He then became an elder of the Japan Sumo Association and worked as a coach at Dewanoumi stable until reaching the mandatory retirement age of 65 in 1983.

He was spotted by the top division wrestler Kasagiyama Katsuichi who persuaded him to join the prestigious Dewanoumi stable.

He held onto his ōzeki rank in 1950, but had a poor tournament in January 1951, being forced to default after four days, missing the next three through injury and then returning to lose another eight straight to finish with a 0–12–3 record.
