Yamamotoyama Ryūta

At 40 years old, Yamamotoyama Ryūta has this physical status:

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 285 kg (628 lb), and Russian sandanme rikishi Orora at 288 kg (635 lb). 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.
