Mongolian ironman Tamawashi became the oldest wrestler in 40 years to regain promotion to sumo's upper ranks, after the 37-year-old was listed as a komusubi on Monday in the Japan Sumo Association's rankings ahead of the Nov. 13-27 Kyushu Grand Sumo Tournament.

Tamawashi, who will turn 38 on Nov. 16, the fourth day of the 15-day meet at Fukuoka Kokusai center, was promoted from a No. 3 rank-and-file maegashira wrestler after winning his second career grand tournament in September.

He will be competing in the three "sanyaku" ranks below yokozuna for the first time since July 2019, and will be sharing the spotlight with sekiwake Mitakeumi.
