Yamamotoyama%20Ry%C5%ABta

, known by his ''shikona'' , or simply Yama, is a Japanese retired sumo wrestler from the city of Saitama in Saitama Prefecture. He made his professional debut in January 2007, and reached the top ''makuuchi'' division in January 2009. His highest rank was ''maegashira'' 9. At , Yamamotoyama is the heaviest Japanese-born sumo wrestler in history, and is also thought to be the heaviest Japanese person ever. In April 2011, he was told to retire by the Japan Sumo Association after he and several other wrestlers were found to be involved in match-fixing. He currently resides in Los Angeles and participates in sumo exhibitions and amateur tournaments, and has made a number of appearances in television shows, commercials and music videos.

Career

Yamamotoyama won several local, national and world sumo championships before entering Nihon University in 2003. He won a total of five championships at Nihon University. He then entered professional sumo as a member of the Onoe stable. He broke the record for the largest new recruit, weighing in at 233 kg in 2007. The previous record holder, Hokutomori, weighed in at 205 kg when he joined professional sumo in 1994. His ''shikona'' or fighting name was created simply by adding the suffix ''yama'' (meaning "mountain") to his own surname. This is common for lower ranked wrestlers but it was rather unusual him to keep it even after reaching ''sekitori'' status. Yamamotoyama however, shares his name with a well-known producer of Japanese seaweed and tea, with whom he was reportedly keen to secure a sponsorship deal.

Yamamotoyama rose quickly through the ranks, recording only one ''make-koshi'' before reaching the second division of ''jūryō'' at the 2008 September tournament. Upon his promotion he posed for photographers with two bags of rice and told reporters that he was aiming for 241 kg in weight, to break the record for a Japanese ''rikishi'' then held by Susanoumi. Only two wrestlers have weighed more than him: Hawaiian born Konishiki at , and Russian sandanme rikishi Orora at . Yamamotoyama once reportedly ate 146 pieces of sushi in a single meal.

After posting nine wins in consecutive ''jūryō'' tournaments, he was promoted to the top ''makuuchi'' division for the 2009 January tournament. The twelve tournaments it took him to enter the top division ties him with Tochiazuma, among others, in a group of the second fastest wrestlers to reach this level. He came through with a ''kachi-koshi'' winning record of 8-7 in his debut ''makuuchi'' tournament, and followed up with another 8-7 in March 2009. He failed to get his ''kachi-koshi'' on the final day of the May 2009 tournament, for only the second time in his career.

He suffered a muscle pull in his ribcage during the July 2009 tournament after falling to the floor of the '' dohyo'' twice in two bouts against Wakakoyu on Day 9 and had to withdraw for the first time in his career. He fell to the ''jūryō'' division for the September tournament as a result. He scored 9-6 there, enough for an immediate ''makuuchi'' return. However he entered the Kyushu ''basho'' in November 2009 in poor condition, having injured his right elbow whilst on tour in October, and he eventually withdrew from the tournament with only two wins, after being diagnosed with influenza. Remaining in the ''jūryō'' division, he suffered knee ligament damage on the 11th day of the July 2010 tournament and was forced to withdraw. Still troubled by the injury, he pulled out on the first day of the September tournament, and as a result was demoted to the ''makushita'' division. Following his loss of ''sekitori'' status, he resumed menial duties at Onoe stable, becoming the head ''chanko'' chef. Due to his injury he was unable to do any ''keiko'' (training) except walking. After fighting only one bout from the rank of ''Makushita'' 13, he withdrew from the November tournament as well. His continuing absence saw him drop to the fourth ''sandanme'' division for the (cancelled) March 2011 basho.

Retirement

In April 2011, along with 18 other wrestlers, he was ordered to retire by the Japan Sumo Association (JSA) after an investigation into allegations of bout-rigging prompted by the discovery of text messages on the mobile phone of fellow ''juryo'' wrestler Kasuganishiki, which alleged Yamamotoyama's involvement in throwing matches. He responded angrily to the decision, saying "The JSA made up its mind from the start that I cheated without listening to me." However, on April 5 he visited the Ryōgoku Kokugikan to hand in his retirement papers, alongside stablemates Sakaizawa and Shirononami who were also found guilty. He had a retirement ceremony at the Tokyo Prince Hotel in September 2011, alongside Sakaizawa. Yamamoto told ''Sports Illustrated'' in 2022, "I was doing it although I knew it was wrong...To tell the truth, you were not fighting as hard as you could." However, he felt that he was scapegoated and the practice was more widespread than the JSA was admitting.

Post-retirement activities

In 2012 he appeared in Season 5 of India's biggest reality show ''Bigg Boss.'' Before entering he told reporters that he had already seen the 4th season and that he loved both the show and Indian culture, despite not knowing Hindi or English. He was given special placards with pictorial representations that helped him to communicate his needs to the housemates. To ensure that Yamamotoyama remained entertained, special activities had been planned during his stay in the house that helped audiences to get some special insights into the life of a professional Japanese sumo wrestler. He entered the house on day 91, as a guest, and bid a farewell after a day of stay there. In their last week Yamamotoyama would teach origami to ''Bigg Boss 5'' inmates.

In 2013 Yamamotoyama participated in a multi-city "Sumo + Sushi" show tour in the United States, co-sponsored by Living Social and USA Sumo. Attendees were shown sumo training exercises and then actual (albeit somewhat restrained) bouts between Yamamotoyama and other sumo stars such Ulambayaryn Byambajav and Kelly Gneiting. In February 2015, Yamamotoyama was the celebrity guest for Koyasan Buddhist Temple’s annual Hoshimatsuri service, where he is a volunteer and regular attendee. In 2014 he appeared in the music video for One Direction's "Steal My Girl." In May 2015, he appeared on the American television program ''The Bachelorette'' along with Ulambayaryn, and in 2017 starred in the music video for the song "Shape of You" by English artist Ed Sheeran. Also in 2017 he was featured in the Hollywood motion picture
'' John Wick 2'' with Keanu Reeves. In June of 2021, Yamamotoyama was featured in th
