Tamawashi will start his 100th career top-division tournament when the May 2026 Natsu Basho opens at the Ryogoku Kokugikan in Tokyo, joining Kaioh and Hakuho as the only sumotori in modern sumo history to reach the milestone.
The 42-year-old Mongolian — born in 1984 and a Makuuchi regular since the late 2000s — has been an institution in sumo's top division for nearly two decades. Two consecutive 5-10 records have dropped him to Maegashira 13 West for Natsu Basho, his lowest banzuke rank since September 2013, when he was Maegashira 16 West.
The slip is real. Tamawashi's win pace has slowed in his early 40s, and the longstanding consistency that defined his 2010s and early 2020s has been replaced by occasional kachikoshi (winning records) interrupted by stretches of make-koshi (losing records). The 100th-tournament context, however, sits above the year-on-year performance question.
Reaching 100 top-division tournaments requires close to 17 years of unbroken Makuuchi presence. Sumo's six-tournaments-per-year calendar, combined with the unforgiving demotion rules between divisions, makes long-term Makuuchi survival exceptional. Most professional sumotori never reach the top division at all. Most of those who do hold their place for fewer than 50 tournaments before injury, weight management or simple ranking pressure pushes them down to Juryo or below.
Only Kaioh and Hakuho — the latter the most-decorated wrestler of the modern era and a Yokozuna for nearly 14 years — have reached 100 Makuuchi tournaments before now. Hakuho's tally was inflated by his decade-long run at Yokozuna 1 East, the rank that does not face demotion. Kaioh's was built on persistent kachikoshi at the Ozeki and Sekiwake levels. Tamawashi has neither distinction. He has reached the milestone the hardest way: by holding his Makuuchi place tournament-on-tournament across more than a decade and a half, as a Maegashira-level wrestler with occasional Sekiwake or Komusubi appearances.
The pressing question for Natsu Basho is whether the 100th tournament will become the 101st. If Tamawashi cannot bounce back to a winning record in May, his Maegashira 13 ranking will leave him exposed to a fast slide into Juryo, which would end any further top-division milestones. A 9-6 or 10-5 record at this level would, by contrast, lift him back toward middle Maegashira and likely guarantee at least one or two more Makuuchi tournaments before age catches up.
The May banzuke also features an Iron Man counterpoint. Mitakeumi, a former Ozeki, climbed one spot to Maegashira 14 East after eight wins in March. He is a younger, faster name on a similar arc — long Makuuchi presence, occasional Sanyaku visits — and his eventual Iron Man tally will likely be among the next to challenge Tamawashi's at the bottom of the division.
For now, the milestone belongs to Tamawashi alone among the active wrestlers. Kaioh and Hakuho have both retired. When the dohyo is purified on day one, Tamawashi will join them.
