Supervisor・Tsuyoshi Mizuguchi

Former sumo wrestler Shoho Tsuyoshi (real name: Tsuyoshi Mizuguchi). He belonged to the Kasugayama stable, made his debut in 2004, and rose to the rank of Makushita East 4. He also performed the Yumitori-shiki (bow-twirling ceremony) on behalf of Yokozuna Hakuho.
After retiring, he has been actively promoting sumo culture both in Japan and abroad through organizing training sessions, producing the YouTube channel "Osumo Gucchan-neru," and hosting sumo experience events.
He appeared as the character Entori in the Netflix drama *Sanctuary* and has also participated in stage performances.
Currently, he organizes inbound sumo events and shows for international visitors, and also works as a personal trainer, sharing the appeal of sumo while supporting people’s health and well-being.

In sumo, one of the most important terms is “Kachikoshi,” meaning a winning record. Each Grand Sumo tournament lasts for 15 days, and wrestlers must fight one bout per day. If a wrestler achieves 8 or more wins, he secures Kachikoshi, which is directly tied to promotion, demotion, and future opportunities. Understanding Kachikoshi allows beginners and international fans to better enjoy the drama and stakes behind each match.

The Basic Meaning of Kachikoshi

In sumo, Kachikoshi refers to finishing a tournament with more wins than losses.
Grand Sumo holds six tournaments each year, and each tournament runs for 15 consecutive days. Wrestlers fight once per day, and their results accumulate to form their final record.

If a wrestler earns 8 or more wins over 15 days, he achieves Kachikoshi. Conversely, with 7 or fewer wins, he suffers a “Makekoshi” (losing record). This rule is simple but extremely important, as it directly influences a wrestler’s rank and career.

8 wins or moreKachikoshiLeads to promotion opportunities or securing rank

15 winsPerfect ChampionshipThe most prestigious achievement of a tournament

Here, 8 wins is the dividing line. Just one win can determine whether a wrestler is promoted or demoted. As a result, great attention is paid to wrestlers approaching that threshold, especially near the end of the tournament.


The Significance and Impact of Kachikoshi

Kachikoshi is far more than just a number.

  1. Condition for Promotion
    For wrestlers aiming at higher ranks, Kachikoshi is the bare minimum. To reach the “Sanyaku” ranks such as Komusubi and Sekiwake, consistent winning records are required. For Ozeki or Yokozuna promotion, multiple double-digit win records are often necessary.
  2. Security of Current Rank
    Achieving 8 wins often guarantees that a wrestler can keep his position. On the other hand, Makekoshi usually results in demotion, sometimes even dropping out of the top division.
  3. Psychological Effect
    Kachikoshi gives wrestlers confidence and momentum for the next tournament. Conversely, Makekoshi brings pressure, forcing wrestlers to regroup and rebuild their strategy.

Kachikoshi and Its Relationship with Rankings

Whether a wrestler achieves Kachikoshi or Makekoshi significantly affects his future rank.

RecordEffect on Ranking
Strong Winning Record (10+ wins)Significant promotion, potential advancement
Bare Minimum Kachikoshi (8–7)Small promotion or rank maintenance
Narrow Makekoshi (7–8)Slight demotion
Heavy Losing Record (10+ losses)High risk of demotion

Thus, even within Kachikoshi, the number of wins makes a big difference in evaluation.


The Tension of “Kachikoshi-Kake”

One of the most exciting scenarios is when a wrestler stands at 7–7 on the final day. This is called “Kachikoshi-Kake,” meaning the bout will decide whether he finishes with a winning or losing record.

Spectators recognize the tension of this situation. The arena fills with anticipation, and when the wrestler wins, thunderous applause erupts. If he loses, sighs and sympathetic murmurs spread. These moments highlight sumo’s dramatic human element beyond just numbers.


Historic Examples of Kachikoshi

Many memorable Kachikoshi stories have emerged throughout sumo history.

  • A wrestler starting with many losses but storming back to achieve Kachikoshi on the final day
  • A newcomer earning his first Kachikoshi, electrifying the crowd
  • A foreign wrestler achieving Kachikoshi, receiving massive support from fans in his homeland

These examples show how Kachikoshi is not just a record but also a moment of inspiration and emotion.


Foreign Wrestlers and Kachikoshi

In recent years, wrestlers from Mongolia, Europe, and other regions have made their mark. When they achieve Kachikoshi, it brings pride not only to themselves but also to their home countries. For international fans, Kachikoshi represents the fruit of hard work on foreign soil.

Example of Foreign Wrestler’s KachikoshiReaction from Fans
Achieving 8 wins in debut tournamentCovered widely by media in home country

Securing Kachikoshi by defeating a YokozunaReported globally in major news outlets

Although sumo is Japan’s national sport, the clear and simple system of Kachikoshi makes it easily understood and celebrated internationally.


The Hidden Meaning Behind the Numbers

While the basic definition is “8 wins or more,” the number of wins within Kachikoshi carries different implications.

WinsEvaluation
8 winsMinimum achievement, often rank maintenance
9–10 winsBoosts promotion prospects
11+ winsOpens the door for awards and higher rank
15 wins (Perfect Record)Historic feat with championship

Thus, while all Kachikoshi records are winning records, not all are valued equally.


Conclusion

Kachikoshi means achieving more wins than losses in a tournament. In the 15-day format, 8 wins is the critical threshold that determines promotion or demotion. Beyond being a numerical record, Kachikoshi carries deep significance: it can spark emotional drama, inspire fans worldwide, and shape the careers of wrestlers.

For beginners and international spectators, keeping an eye on wrestlers nearing Kachikoshi makes sumo more engaging and easier to understand. Ultimately, Kachikoshi is both a statistical milestone and a powerful storytelling element in the ancient sport of sumo.
