Takanoiwa Yoshimori (born 26 February 1990 as Adiyagiin Baasandorj) is a retired sumo wrestler from Ulaanbaatar, Mongolia. He made his professional debut in January 2009. He has both a sandanme and a jūryō division championship. He reached the jūryō division in July 2012 and the top makuuchi division for the first time in January 2014. He is the first wrestler recruited by former yokozunaTakanohana to reach the elite sekitori ranks. He has been runner-up in one top division tournament and earned two special prizes, one for Fighting Spirit and one for Outstanding Performance. His highest rank was maegashira 2.
Takanoiwa was the victim of an assault by sumo wrestler Harumafuji in October 2017. Takanoiwa was then the assailant in an incident against a junior member of his own stable the following year, which led to his retirement from the sport.
Baasandorj passed a selective test administered by a Japanese coach from Johoku High School in Shimane Prefecture, who had come to Mongolia looking for sumo prospects. He was then invited to come to Japan as an exchange student on a sumo program at the age of sixteen. Only three months after coming to Japan, his father died of liver disease in Mongolia. He had already lost his mother to heart disease when he was eight years old. Through this adversity, he still managed to excel, and in 2007 made the best four in the individual category at a national junior sumo competition and in 2008 finished second in the middle-weight category at the
World Junior Sumo Championships held in Chiang Mai, Thailand.
