Three Regions Clash! M League Men's Team Competition.

In a round-robin format, each school will play two matches, with only one advancing to the final tournament.

Highlights
Round-robin tournament between three schools; only one school advances.
The preliminary league will be a round-robin between three schools, with each school playing two matches. The team match consists of five members: Senpo, Jiho, Chuken, Fukusho, and Taisho. The winner will be decided by the number of wins, and if tied, by the number of points. In the official results of the previous tournament, the number of wins and points were listed together, such as "3(6)-1(2)". Only one school from each league can advance to the knockout tournament, and if they lose even one match, their summer is over. The one school that advances from Mリーグ will play against the winner of Nリーグ in the first round of the knockout tournament.
From one member, a correspondence course national best 8・Seisa
Kagawa Prefecture's "Seisa" is, officially, the Takamatsu Learning Center (Takamatsu City, Shioage-cho) of Seisa International High School, operated by the School Corporation International Gakuen, a wide-area correspondence and unit-credit system high school. According to the school's website, the kendo club started with one member in fiscal year 2020 and has been working towards the goal of becoming "number one" in Japan. From there, they reached the best 8 in the men's team at the Hiroshima Inter-High in Reiwa 7 (2025) and 5th place at the 79th National Sports Festival (Shiga). The very fact that a learning center in a correspondence course has made it into the top 8 schools nationwide is the biggest highlight of this league.
Shikoku tournament individual champion・松村太樹 player
Seisa’s male individual representative, 松村太樹 (3rd year, 3rd dan), won the individual competition at the Shikoku High School Kendo Championships (men’s 72nd) in June 2026. According to the results published by the Kagawa Prefectural Kendo Federation, the opponent in the final was 野田宗佐 from Johoku (Tokushima). Seisa also won both the team and individual competitions in the Kagawa Prefectural preliminaries, and at the Kagawa Prefectural High School Rookie Tournament in Reiwa 7, the school dominated the men’s individual competition, taking first, second, and third place. Some media outlets write the surname as “Muramatsu,” but the official notation of the Kagawa Prefectural Kendo Federation is “Matsumura.”
First appearance・Aisandaimikawa immediately in the first match against Seisa
Aichi Prefecture Okazaki City’s private school, Aichi Sangyo University Mikawa High School, opened in April 1983 as “Mikawa High School” and was renamed to its current name in 1995, making it a relatively new school. Its school motto consists of five principles: “Gratitude, Courtesy, Sincerity, Proactivity, and Effort.” In addition to the general academic course (Type I, Type II, Type III), it also has an electrical engineering course and an information processing course. The kendo team is a strong school that won the Tokai Tournament in winter, but this is their first Inter-High appearance. Their first match on this debut stage is against Seisa, who were in the best 8 last time. Let's Kendo reports that they are “a team built around local players, competing with teamwork.”
Starting position from the second match Saikyo
Saikyo, representing 山口 Prefecture, is 山口 Prefectural Saikyo High School located in Kurokawa, 山口 City. Established in 1986, it has a relatively short history and consists of a General Course, General Course Physical Education Course, Comprehensive Business Course, and Information Processing Course, with the school motto "Enterprising — Creative, Trustworthy, Healthy, and Harmonious." With the skill to reach the top 8 of the Chugoku Regional Tournament, 橋本十座 (3rd year, 2nd dan) will compete in the boys' individual event. The first league match is between Seisa and Aisandaimikawa, and Saikyo will appear starting from the second match. While there is an advantage in being able to observe the strength of both schools before competing, unlike the other two schools that cannot afford to lose their first match, Saikyo is in a position where they cannot afford to lose either of their two matches.
A prelude to the Shikoku showdown.
A school that advanced through M League will face the winner of N League in the first round of the final tournament. That N League includes Nitta (Ehime), which won the boys' team event at the Shikoku High School Kendo Championships in June 2026. Both Seisa (Kagawa) and Nitta (Ehime) are representatives from Shikoku; at the Shikoku tournament, Nitta won the team event, and 松村 of Seisa won the individual event. If both schools win their respective leagues, the continuation of Shikoku's summer will take place in the first round of the final tournament in Nara.

Messages of support for the participating schools and players.
Seisa, Aisandaimikawa, Saikyo—To the three schools of M League. Seisa, which started with one member and reached the national top 8, and 松村太樹 player, who won the individual competition in Shikoku. Aisandaimikawa, which dominated the winter Tokai region and challenges the national stage for the first time with local teammates. Saikyo, raising the banner of progress and entering from the Chugoku region with 橋本十座 player. The distance walked and the signboard carried are different, but on this floor, everyone is a swordsman chasing the same ippon. Two schools will leave on the first day in a round-robin format. Nevertheless, the first step for first-timers and the re-challenge for those who know the upper ranks are both not easy. Please confidently demonstrate what you have built up without hesitation.
To the five members from Senpo to Taisho.
The kendo club of Seisa started in fiscal year 2020 with one member, according to the school's announcement. The path to reaching the national best 8 could not be walked by one person alone. Currently mentioned are Seisa’s 松村太樹 player and Saikyo’s 橋本十座 player, while the first-time appearance of Aisandaimikawa is yet to come. There are only two qualifying spots per prefecture for the individual competition. The team competition is a five-person system. From Senpo to Taisho, all five members wear protective gear and aim to score ippon. If the lineup is announced on August 2nd, fifteen names will be complete. There isn’t a single player without a name. Let us hear those names in Nara.
