Aomori Yamada vs Higashi Nippon

The game remained scoreless through three innings as Terunuma and the Aomori Yamada starter traded zeros. Terunuma, who had already thrown 141 pitches in the first round, worked out of a jam in the second inning with a double play to escape without damage.

Higashi Nippon broke through in the fourth inning. Captain Mine led off with a single to left, advanced on an error, and scored when No. 6 hitter Shoryo Kanazawa singled to centre for a 1-0 lead.

Aomori Yamada answered immediately in the top of the fifth, stringing together consecutive hits to tie the game 1-1. The deadlock lasted only half an inning.

The fifth inning began with the score tied 1-1 and ended with Higashi Nippon holding a commanding 6-1 lead. No. 9 hitter Onouchi reached on a fielding error by the Aomori Yamada defence, which committed two errors on the day. The mistake allowed the go-ahead run to score.

With the bases loaded and one out, cleanup hitter Midorikawa grounded to second base, plating another run. Two outs later, with runners on second and third, Kanazawa delivered again — a centre-field single that drove home two more. By the time the inning ended, Higashi Nippon had sent nine men to the plate and scored five times, turning a tight contest into a rout.

Aomori Yamada managed one run in the sixth inning to cut the deficit to 6-2, but Terunuma shut the door from there, retiring the side in order in the final innings.

Yutaka Terunuma (Higashi Nippon) — Player of the Match: The ace went the full nine innings for the second straight game, throwing 112 pitches while allowing 2 earned runs on 7 hits with 1 walk and 6 strikeouts. Per the X account Highschool Baseball in Japan, this was Terunuma's second complete-game win of the tournament after he struck out 7 in the first round on 141 pitches.

Shoryo Kanazawa (Higashi Nippon): The six-hole hitter drove in a team-high 3 RBIs, delivering two centre-field singles in key scoring situations. His father Masayuki, who played in the Spring Koshien final for Sendai Ikuei, watched from the stands, per NTV News.

Aomori Yamada defence: Two errors proved costly, particularly the fifth-inning miscue that allowed the decisive rally to continue. Seven hits were not enough to overcome the defensive lapses.

The box score (8 hits to 7, 1 error to 2) tells a story the final 6-2 scoreline amplifies. Higashi Nippon's five-run fifth — more runs than Aomori Yamada managed in the entire game — was the decisive gap, not sustained dominance across nine innings. Terunuma's efficiency (112 pitches, 1 walk) kept Higashi Nippon out of trouble. Aomori Yamada's 7 hits were scattered across five different innings, but they never strung together the multi-run rally needed to reclaim momentum.

Higashi Nippon's 1 error to Aomori Yamada's 2 might look like a narrow margin, but timing mattered: Aomori Yamada's fifth-inning error directly fuelled the five-run outburst.

Higashi Nippon advanced to the third round — the school's best ever Koshien result in either the spring or summer tournament. Per NTV News, this was their "second win at Koshien" and secured a top-16 finish in their debut Summer Koshien appearance.

Aomori Yamada, spring Tohoku tournament semi-finalists, were eliminated in the second round.

Higashi Nippon face Ariake High School from Kumamoto on 16 August in the third round, with a quarter-final berth on the line. Both schools are chasing a top-eight finish for the first time.

Higashi Nippon's five-run fifth was the game's only real burst of offence, and it was enough. Terunuma's durability — back-to-back complete games in a high school tournament's heat — was the foundation. Aomori Yamada will wonder what might have been without the defensive lapse that turned a 1-1 game into a 6-1 deficit. For Higashi Nippon, a small school from Fukushima, the dream run continues.
