Chiyotaikai Ryūji, Japanese sumo wrestler
Chiyotaikai Ryūji (born April 29, 1976 as Ryūji Hiroshima in Chitose, Hokkaidō), is a Japanese former sumo wrestler. He made his professional debut in 1992 and reached the top makuuchi division in 1997. He held the second highest rank of ōzeki or champion for 65 consecutive tournaments from 1999 until 2009, making him the longest serving ōzeki in the modern era. He won three top division yūshō or tournament championships, and was a runner-up on seven other occasions. However, he also held the dubious record of being in danger of demotion from ōzeki fourteen times. He wrestled for Kokonoe stable until his retirement in January 2010 at the age of 33. He remained in sumo as a coach at his stable, and became the head coach in August 2016 following the death of Chiyonofuji.
