Takeshi Seirō

is a Mongolian former professional sumo wrestler. He made his professional debut in July 2005. After a decade of competing in the lower ranks of sumo he reached the top division for the first time in 2015. His highest rank was maegashira 14. He wrestled for Shikoroyama stable. He retired in July 2020.

Early life and sumo background Amgaa Unubold was born on 18 August 1988 in Ulan Bator, Mongolian People's Republic. His father was a successful Mongolian wrestler with a rank the equivalent of sekiwake. Then-yokozuna Asashōryū noticed his talent and word got to the head of Shikoroyama stable, the former Terao, who had come scouting to Mongolia. Unubold accepted an invitation to come to Japan to enter sumo and while still a teenager he joined said Shikoroyama stable, taking the ring name (shikona) Seirō, meaning "blue wolf".

Career Seirō made his debut as a 17-year-old in September 2005 when he won five of his seven bouts in the lowest jonokuchi division and was immediately promoted to jonidan. He competed in jonidan for the next ten tournaments, recording more wins than losses (kachi-koshi) on six occasions before being promoted to the sandanme division for the July tournament in Nagoya in July 2007. After four consecutive kachi-koshi he was promoted to the makushita division in March 2008 but dropped to sandanme after losing four of his seven bouts. In the May tournament of 2009 he was unbeaten in seven contests, taking the championship in that division, securing his second promotion to makushita. Injury problems in early 2010 saw him relegated briefly to sandanme but he returned to makushita for the Nagoya tournament in July. After another three years in the division, Seiro was promoted to jūryō rank in July 2013. In the May 2014, he took part in a four-man playoff for the jūryō championship which would eventually go to Ichinojō. A losing record saw him return to makushita after the May tournament, but he once again earned a promotion to jūryō after the July tournament. However his return to jūryō was short-lived as he withdrew from the September 2019 tournament with only two wins.

Retirement from sumo Seirō announced his retirement before the July 2020 tournament, citing a number of health problems including meningitis.

Seirō's danpatsu-shiki (retirement ceremony) was held in Tokyo on 20 August 2022.

Fighting style Seirō favoured a left hand outside, right hand inside (migi-yotsu) grip on his opponent's belt. He employed a wide variety of winning techniques (kimarite) but his most common was yorikiri or force-out which accounted for more than 30% of his wins. He also made frequent use of uwatenage (outer arm throw) and yoritaoshi (front crush-out). Their wedding reception was held on 10 June 2018 with 250 guests in attendance most notable of which being Shikoroyama-oyakata, Hakuhō, and Kakuryū.
