Tamarikidō Hideki

In August 2020 it was announced that he had tested positive for COVID-19, although he had not been displaying symptoms and was not believed to have been in close contact with other sumo personnel during the most recent tournament.

Tamarikidō retired after the January 2010 tournament, with a final day defeat to Kitazakura leaving him with a 1–6 record. His danpatsu-shiki, or retirement ceremony, was held in June at the Ryōgoku Kokugikan. He stayed in sumo as a coach at Kataonami stable under the toshiyori name Araiso Oyakata. In June 2013 he switched to the Nishonoseki name after it was vacated by the retiring stablemaster Kongō. In 2014 he swapped elder names with Matsugane Oyakata, the former ōzeki Wakashimazu, and joined the renamed Nishonoseki stable.

He eventually managed to return to the jūryō division in March 2006, and having fallen to sandanme 80, he was the lowest ranking former top division wrestler ever to regain sekitori status. He had climbed as high as jūryō 4 by the November 2006 tournament. However, he was demoted back to the unsalaried ranks after the September 2007 tournament when he managed only a 3–12 score at jūryō 12. He continued to slide down the rankings, with four consecutive make-koshi scores of 3–4 from November 2007 to May 2008. After recording only one win in November 2008 he was demoted back to the sandanme division for the January 2009 tournament. He made an immediate return to the third division with a 6–1 score.

Tamarikidō made his debut in the top makuuchi division in January 2001. He has spent eleven tournaments in the top division in total, the last in November 2003 when he had to withdraw after winning only two bouts. 2004 was a disastrous year for him as a knee injury in May meant he missed nearly all his matches and fell to the fourth sandanme division. It was subsequently discovered that due to the lack of treatment of earlier injuries, his anterior cruciate ligament was completely worn away. He began his comeback in 2005, winning the sandanme division championship in March of that year.

He was born in Edogawa, Tokyo, and is a third generation Korean-Japanese. He was a teammate of Takanohana at the Meidai Nakano High School's sumo club. He was also a former amateur sumo champion at Meiji University, and was considered extremely promising. He came third in the All Japan Sumo Championships. He made his professional debut in March 1997 at the bottom of the third makushita division. He was a runner-up in his first tournament but had a few setbacks before finally reaching the second highest jūryō division in September 1999.
