Katsuya Kitamura was a Japanese professional wrestler, bodybuilder, and amateur wrestler trained by New Japan Pro-Wrestling, where he was the winner of the 2017 Young Lion Cup.
Before becoming a professional wrestler, Kitamura was a highly accomplished amateur wrestler, known for being one of the largest wrestlers in all of Japan.
Because of his size and physique, he earned the nickname “Wrestling Monster”. He attended Senshu University, where he was a part of their wrestling team.
In 2006, he won the All Japan Wrestling Championship in the 120 kg category, and later on, in the same year represented Japan in the World Championships.
After undergoing further training, Kitamura wrestled his first ever professional match on September 1, 2016, at Lion’s Gate Project 3, another dark match where he and Oka once again wrestled to a draw.
On March 13, 2017, he made his televised debut, teaming with Oka in a loss to the Guerrillas of Destiny (Tama Tonga and Tanga Loa).
On June 24, 2017, three months after his debut, Kitamura won the first match in his career when he teamed with Tomoyuki Oka to defeat Manabu Nakanishi and Tetsuhiro Yagi in a tag match. Kitamura and Oka continued teaming regularly, eventually dubbing their team “Monster Rage”.
At The New Beginning in Hiroshima, he was scheduled to face Manabu Nakanishi, but he suffered a cerebral concussion and was unable to compete.
It was reported that the severity of the injury may force him to retire. After almost a year with little news or updates on his condition, Kitamura left NJPW on January 31, 2019.
Kitamura died on October 13, 2022, at the age of 36.
His funeral arrangement is to be announced by the family.
