History

edit


Yoshii has been practicing judo since he was 5 years old, [3] but after winning a local sumo tournament, he started attending the local Yaizu Sumo Club.[4] In his 5th year of elementary school, he reached the top 16 in the National Children's Sumo Tournament, and in junior high, he won Junior High School Yokozuna.[3][4]After graduating from junior school, he joined the Nakagawa stable of professional sumo and made his debut in the March 2019 tournament.

Career

edit

In the May 2019 tournament, his first time in the Jonokuchi division , he achieved a winning record of 5 wins and 2 losses.[1] In the following July tournament, after being promoted to the Jonidan division, he also advanced in just one tournament with a record of 6 wins and 1 loss. After being promoted to the Sandanme division, he achieved winning records for four consecutive tournaments, and in May 2020 he was promoted to the Makushita division at the age of 16 years, 8 months, and 26 days. This was the third youngest promotion in history for a sumo wrestler who made his debut after 1972 , when entry into sumo before graduating from junior high school was prohibited. [5]

In July 2020, just before the July tournament, his stable, Nakagawa stable, was closed due to a scandal caused by his stablemaster, so he transferred to Tokitsukaze stable. [6] In his first tournament in the Makushita division after transferring stables, he secured a winning record on the 13th day, becoming the first 16-year-old to achieve a winning record in the Makushita division since Takanohana (the 65th Yokozuna).[7]

In the September tournament of the same year, he injured the ligament in his right thumb before the tournament but competed anyway and achieved a winning record. [3] However, due to the effects of surgery he underwent after the tournament, he missed the following November tournament, and was demoted to Sandanme.[3] He scored 6 wins and 1 loss, returning to the Makushita division in just one tournament. [1]

In the July 2022 tournament, where he competed as East Makushita 38, he won all 7 matches and won the Makushita championship, his first championship in any division. [2] In the September tournament, he rose to his highest rank of East Makushita 3, where a winning record would put him in contention for promotion to Sekitori, but he failed to achieve promotion. [1]

In the January 2023 tournament, with a record of 2 wins and 3 losses, he faced Otsuji in his sixth bout, their first match since the 2018 All-Japan Junior High School Individual Championships final. He grabbed his opponent's right arm with both hands and ultimately won with an arm twist. [8] In the May 2024 tournament, where he entered the ring at the rank of West Makushita 7, he achieved his first winning record at a rank within the top 15 of the Makushita division.[1]
