Tohin Daishohei Score Five in Fifth to Lead Aomori Yamada 6-2 at Koshien

On Thursday, August 13, 2026, 東日本国際大昌平 (Tohin Daishohei) — the Fukushima Prefecture representative making its first-ever appearance at the 108th Summer Koshien — broke open a Tohoku regional showdown against Aomori Yamada with a five-run fifth inning, building a 6-2 lead in the second round at Hanshin Koshien Stadium. Ace right-hander Yutaka Terunuma held the powerful Aomori lineup to one run through five innings, and Fukushima’s offense finally woke up after a scoreless start against one of the tournament’s deeper batting orders.

How Tohin Daishohei built the lead

Terunuma quieted Aomori early

Terunuma, who threw a 141-pitch complete game in a 2-1 first-round win over Shirakaba Gakuen on August 8, returned on four days’ rest with his usual low-140s km/h (~87–88 mph) fastball and slider. Through five innings he allowed just one run against an Aomori lineup built around left-handed table-setters and right-handed middle-order thumpers.

Analysts before the game had flagged Aomori’s 1-2-3 left-handed hitters as the key test for Terunuma, who had held lefties to a sub-.100 batting average in Round 1 but gave up his only earned run to a right-handed batter. On August 13, the ace largely solved that puzzle in the early frames, keeping Fukushima within striking distance until the offense arrived.

Fourth inning: Kanazawa breaks through

After three scoreless innings on both sides, Tohin Daishohei finally cracked the scoreboard in the bottom of the fourth. Leadoff hitter Daitama Mine singled to left, advanced on a wild pitch and productive outs, and reached third with two away. Cleanup-adjacent bat Takumi Kanazawa — batting sixth — delivered a center-field RBI single to make it 1-0.

It was the kind of small-ball sequence Tohin Daishohei had leaned on all tournament: manufacture traffic without waiting for home runs. In its prefectural run, Fukushima had reached Koshien by beating five-time defending Fukushima champion Seiko Gakuin in the semifinals and routing Gakuhō Ishikawa in the final.

Fifth inning: five-run rally, lineup turns over

The decisive burst came in the bottom of the fifth. With no outs and a runner on first, No. 9 hitter Isssei Kouchi ripped a two-run double to left-center for a 2-0 lead. Aomori Yamada could not stop the bleeding:

• With one out and the bases loaded, No. 4 Fuuma Midorikawa grounded to second; a run scored on the play to make it 3-0.
• Fukushima added another run on a productive out before Kanazawa struck again — his second RBI single to center — with two outs and runners in scoring position.

The rally sent nine batters to the plate and pushed the score to 6-0 before Aomori finally recorded the third out. Kanazawa finished the frame with two clutch hits in a game where Tohin Daishohei had managed only modest offensive output in its Koshien opener.

Aomori’s pushback

Aomori Yamada, which had survived a 6-5 nail-biter against Yugakukan in Round 1 after building a 6-0 lead, did not fold. The school scored once in the sixth and once in the seventh, trimming the deficit to 6-2 and forcing Terunuma and Fukushima’s bullpen to protect a four-run cushion into the late innings.

Stakes for both schools

Tohin Daishohei: chasing a second Koshien win

Tohin Daishohei — formally Higashi Nippon Kokusai University Shohei — is making its first Koshien appearance in either the spring or summer tournament. Its Round 1 victory over Shirakaba Gakuen was Fukushima’s first summer Koshien win since Seiko Gakuin in 2023 and the first for an Iwaki-area school since Iwaki reached the quarterfinals in 1975.

The program’s breakthrough summer included a 3-2 semifinal upset of powerhouse Seiko Gakuin and a 10-7 prefectural final over Gakuhō Ishikawa. Round 1 hero Hayato Irikemachi had delivered the walk-off RBI single in the ninth after a video-review overturn on a pickoff play — one of the first reversed calls under Koshien’s new replay system.

A win over Aomori Yamada would send Fukushima to the round of 16 and keep alive one of the tournament’s most compelling underdog runs.

Aomori Yamada: experience vs. momentum

Aomori Yamada was making its 13th Summer Koshien appearance and seeking a deep run after a two-year absence from the national stage. The program’s Round 1 escape against Yugakukan showcased both its firepower — six runs through three innings — and its vulnerability when leads shrink in single-elimination play.

Captain Soraya Gundoshi, who is from Fukushima and recorded his first hit of the summer in the opener, had spoken before the game about facing a hometown opponent: “If we all do what we’re supposed to do, we can win — so we’ll prepare together and go into the next game ready.” Aomori needed a comeback to extend its season on August 13.

What the result means for the bracket

Round 2 on Day 9 also featured matchups including Ariake vs. Nagasaki Nichidai and Oita Shōgyō vs. Eimei. The winner of the Tohoku duel advances to Round 3, where roughly 13 schools remain in the 49-team bracket toward the August 22 final.

For Tohin Daishohei, the fifth-inning explosion answered pregame questions about whether its lineup could punish a pitching staff that had used multiple arms to reach Koshien. For Aomori Yamada, the 6-2 hole underscored the cost of letting a first-time Koshien school hang around against an ace who had already proven he could pitch through tight games.

Discussion

A Fukushima school that had never smelled Koshien dirt until this August suddenly had a four-run cushion against a 13-time national tournament program — and the fifth inning told the story.

1. Kanazawa drove in three runs with two singles in the fifth after Tohin Daishohei had scored just two runs in its entire Round 1 game. Does one explosive inning change how you evaluate a team that otherwise grinds out low-scoring wins?

Can Fukushima keep that offensive burst going, or was it a one-inning spike against Aomori’s bullpen?

2. Terunuma threw nine innings four days earlier and was back on the mound against a lineup built to test his splits. How much does a complete-game workload in Round 1 affect a Koshien ace in Round 2 — and when should a manager turn to the bullpen to protect a 6-2 lead?

Aomori preserved ace lefty Kōnosuke Kawakubo in relief during its opener. Did that pitching-management gap show on August 13?
