第98回選抜高校野球大会は2026年3月19日(木)に開幕する。同大会には運営委員会において選出された32校が出場する。

選出の重要参考資料となる各地方大会は既に終了。ここでは、同大会の結果を踏まえた出場想定校を紹介する。


2026年選抜高校野球 出場校想定

The breakdown for the 98th National High School Baseball Invitational Tournament includes 29 schools selected through general application, 2 schools via the 21st Century selection, and 1 school from The Jingu Tournament slot. In the Meiji Jingu Tournament held in November, Kyushu's representative, Kyushu Kokusai University Affiliated High School, emerged victorious. Consequently, the Jingu Tournament slot was awarded to Kyushu. The list of participating schools will be revealed on Friday, January 30, 2026.

以下、出場校想定。印は★当確、◎出場濃厚、○有力、△微妙
(筆者の想定であり、公式の情報ではありません)


北海道(1校)

北照(北海道大会優勝)
△白樺学園(同準優勝)

秋の道大会を制した北照が順当に選出されるとみる。

If they advance, it will be their sixth appearance, the first since 2013, marking 13 years. After defeating Hokkai, who eliminated them in the quarterfinals this summer, in their first match, they successively defeated perennial Koshien contenders Komadai Tomakomai, Asahikawa Jitsugyo, and Shirakaba Gakuen. Centered around their ace pitcher, Sosuke Shimada (2nd year), who pitched all four games of the all-Hokkaido tournament alone, they will implement a defensive style of baseball.


東北(3校)

花巻東(東北大会優勝、岩手1位)
◎八戸学院光星(同準優勝、青森1位)
○東北(同4強、宮城2位)
△聖光学院(同4強、福島1位)

優勝の花巻東、準優勝の八戸学院光星は順当に選出されるだろう。

The third challenge involves a comparison between two schools that reached the semifinals of the Tohoku tournament, with 東北 being viewed as the stronger contender. In that tournament, they achieved decisive victories by an 8-point margin in both their first game and the quarterfinals. They then put up a close fight in the semifinals, losing by 3 points to Hanamaki Higashi, who later reached the semifinals of the Meiji Jingu tournament. Furthermore, they committed only one error over 27 innings. Their overall strength is considerable.

聖光学院は準々決勝で今夏甲子園16強の仙台育英を破った。しかし、同大会3試合25イニングで失策4、準々決勝の八戸学院光星戦は0ー7での敗戦。東北との比較では劣勢に映る。
 


関東・東京(6校)

山梨学院(関東大会優勝、山梨位)
帝京(東京大会優勝)
◎花咲徳栄(関東大会準優勝、埼玉1位)
◎専大松戸(関東大会4強、千葉1位)
◎佐野日大(関東大会4強、栃木1位)
△横浜(関東大会8強、神奈川1位)
△関東第一(東京大会準優勝)
△浦和学院(関東大会8強、埼玉2位)

In addition to the top four from The Kanto tournament, Teikyo, the champions of the Tokyo tournament, will likely be selected without issue. The challenge lies in selecting one school from the eight Kanto quarterfinalists and Kanto Ichi, the runner-up in the Tokyo tournament. While Yokohama, Kanto Ichi, and Urawa Gakuin all have a strong chance of participating, I believe 横浜 holds an advantage here.

Although they were defeated by a single hit in the quarterfinals against Sendai Matsudo, they limited opponents to 6 hits through the pitching of first-year student Kobayashi and the absolute ace Oda. The team's strong defense, with only 1 error in 18 innings, along with the fact that many members from last year's Spring Koshien championship and Summer Koshien top 8 are still on the roster, the regional advantage of Kanagawa with its many baseball fans, and the school's status as a traditional powerhouse with a nationwide following, are all cited as strong points.

The Kanto region's top team demonstrates considerable overall strength, scoring over 9 points and allowing fewer than 2 points in all matches leading up to the prefectural final. Their powerful offense was evident in the final, with 16 hits significantly outperforming their opponent. However, they failed to capitalize on their opportunities, scoring only 4 runs. Furthermore, the selection committee will need to consider how they view the team's inability to halt the momentum after conceding 8 runs in the third inning.

浦和学院は準々決勝で優勝校の山梨学院に3ー6と接戦の上での敗戦と力をみせた。しかし、同じ埼玉の花咲徳栄が準優勝で当確している点と、2試合で計12失点と大味な試合が続いた点が気になる要素だ。

関東大会8強の甲府工、駿台甲府はそれぞれコールド負けに加え、関東大会王者の山梨学院が山梨県勢で既に当確。地域制の観点からも、ここは厳しいか。


東海(3校)

中京大中京(東海大会優勝、愛知1位)
◎三重(同準優勝、三重1位)
△大垣日大(同4強、岐阜1位)
△聖隷クリストファー(同4強、静岡1位)

王者の中京大中京、同校と決勝戦で延長10回7ー8の死闘を繰り広げた三重の2校は文句ない選出を果たす。

The remaining school appears to be favored by 大垣日大. The comparable team, Seirei Christopher, was defeated by Mie in the semifinals with a 7-inning mercy rule, losing 2-10 by a wide margin. While they have a notable pitcher, Riku Takabe, who is a prospect for next autumn's draft, how will they fare against Ogaki Nishi, who put up a close fight against the championship-winning Chukyo University Chukyo in the semifinals, losing 4-6?

聖隷クリストファーは2022年、東海大会で準優勝を果たしながら選抜出場を逃した。その時に比較で選ばれたのが4強の大垣日大。奇しくも今回も両校の比較となりそうだ。


北信越(2校)

帝京長岡(北信越大会優勝、新潟3位)
◎日本文理(同準優勝、新潟1位)
△星稜(同4強、石川3位)
△敦賀気比(同4強、福井1位)

北信越大会優勝校の帝京長岡、準優勝の日本文理が順当に選出され、新潟県からの2校選出となるだろう。

両校とも北信越大会の4試合はいずれも3点差以内の接戦を戦った。決勝戦も5ー4と僅差のゲームだった。戦力差が大きく離れていない結果から、番狂わせの選出は考えづらい。


近畿(6校)

神戸国際大附(近畿大会優勝、兵庫1位)
◎智弁学園(同準優勝、奈良1位)
○大阪桐蔭(同4強、大阪1位)
○滋賀学園(同4強、滋賀3位)
△東洋大姫路(同8強、兵庫3位)
△近江(同8強、滋賀1位)
△橿原学院(同8強、奈良3位)

近畿大会王者で明治神宮大会準優勝の神戸国際大附は堂々の選出を果たす。同校に近畿大会決勝戦で8回表終了まで6ー6と接戦を演じた智弁学園も文句なく出場だ。

The four strong schools are expected to advance without issue. Osaka Toin lost to Kobe Kokusai University Affiliated in the semifinals with a score of 1-7, but they secured victories with large margins in their earlier matches, defeating Ichinomiya Wakayama 7-1 in the first round and Tenri 10-0 (6-inning mercy rule) in the quarterfinals. With a total of 30 hits across three games, their offensive prowess is outstanding.

滋賀学園は3試合で複数失策なし。準決勝こそ7失点したものの、それまでは2試合18イニングで3失点。守りの堅さは大きな評価につながる。

The remaining two schools are expected to be favored by 近江 and 東洋大姫路. Omi lost in the quarterfinals after a close game that remained 1-1 until the bottom of the ninth inning against Shiga Gakuen, ultimately losing by a walk-off hit. There wasn't a significant difference between the two teams. Furthermore, they've only allowed 3 runs over 16 innings across two games, with zero errors. Their high level of defense is a strong selling point.

Toyo University Himeji engaged in a close contest with the runner-up Chiben Gakuen, remaining tied at 5-5 until the bottom of the ninth inning in the quarterfinals. Despite the challenging circumstances of a rain-interrupted continuation match, the team's depth was evident, highlighted by Pitcher Sohma Mikami, wearing number 11, who delivered a tenacious performance over seven innings, allowing only two runs.


中国(2校)

崇徳(中国大会優勝、広島2位)
◎高川学園(同準優勝、山口4位)
△下関国際(同4強、山口1位)

The champions of the China tournament, Shūtoku, and the runners-up, Takagawa Gakuen, are expected to be selected without issue. Shūtoku's ace pitcher, Riku Tokumaru, is their cornerstone. He completed all four games, allowing just one run over 33 innings. He delivered excellent performances in both the semifinals and finals, limiting opponents to just three hits each, and expectations are high for his pitching in Kōshien.

高川学園は初戦の広陵戦こそ2失策あったが、それ以降の3試合は無失策と堅い守りを披露。守備力の高さは高評価につながる。


四国(2校)

英明(四国大会優勝、香川2位)
◎阿南光(同準優勝、徳島1位)
△明徳義塾(同4強、高知1位)

四国大会優勝&全4試合を2失点以内に抑えた英明は文句のない選出を果たす。

準優勝の阿南光も戦績通りに出場濃厚とみるが、決勝戦が英明に2ー7で敗戦など3試合で12失点と大味な試合を戦ってきた。加えて準決勝は相手の藤井が7失策。エラー絡みで得た点数が複数あった。

Meitoku Gijuku, one of the four strong teams, lost a close game 1-2 to Eimei in the semifinals. Their defense was solid in the quarterfinals against Tokushima Commercial, allowing only one run with no errors. Given that Seirei Christopher, the runner-up in the Tokai tournament the previous autumn, was left out of the 2022 Spring selection, while Ogaki Nihon University, a semifinalist, made it to the Spring tournament, it's not guaranteed that selections will strictly follow the rankings.


九州(4校+神宮大会枠1)

九州国際大付(明治神宮大会&九州大会優勝、福岡1位)
◎長崎日大(九州大会準優勝、長崎1位)
○神村学園(同4強、鹿児島1位)
○熊本工(同4強、熊本1位)
△沖縄尚学(沖縄1位)
△小林西(宮崎1位)

九州大会制覇の勢いそのままに明治神宮大会を制した九州国際大付は、文句なくセンバツ出場を果たす。

準優勝の長崎日大は九州大会決勝戦で7回終了時点で2-0とリード。力差のない結果だけに、ここも文句はない。

4強勢の2校も当確と言える。神村学園は準決勝で九州国際大付に1点差の4ー5と接戦を演じた上に、準々決勝では夏の甲子園王者で当時の左右エース二枚看板が残る沖縄尚学に勝利。文句のない戦績だ。

熊本工は準決勝で7回終了時点まで長崎日大に3-0でリードするなど、こちらも力差はない。加えて3試合27イニングで失策は1と守りが堅い。減点ポイントが少ない点は魅力だ。

神宮大会枠で与えられた1校だが、ここは 沖縄尚学 を優勢とみる。

As previously mentioned, they are the undisputed champions of this summer. Their overwhelming pitching strength, featuring left-handed ace Ryosuke Sueyoshi and right-handed ace Arihiro Aragaki, who also shone brightly at Koshien, is among the nation's elite. Sueyoshi, despite being a sophomore, was selected for the U18 Japan national team and has been performing extensively since this summer. Although he only pitched a total of 4 innings in the Kyushu tournament, his continued brilliance is anticipated next year once he's back to his full form.

また、沖縄は今夏甲子園決勝戦でも大きく報じられたように高い野球熱を誇る。ここは地域制の観点からも有利だと言える。
