On Tuesday, August 18, 2026, Day 13 of the 108th National High School Baseball Championship — Japan’s Summer Koshien — brought quarterfinal results to Hanshin Koshien Stadium in Nishinomiya, Hyogo. Four best-eight schools faced single-elimination games that would set half of the semifinal field for August 20. In the opening quarterfinal, Tenri (Nara) routed Mie (Mie Prefecture) 7-0 to reach the semifinals for the first time since 2017.

Six of the eight remaining schools had previously won a national title at Koshien. Hanamaki Higashi (Iwate) carried spring Koshien pedigree, and first-time summer participant Ariake (Kumamoto) arrived on a run of three straight comeback wins. Ticket demand reflected the stakes: the federation announced on August 17 that all seats for Day 13 had sold out, with no same-day tickets available.

Game 1 produced the day’s first semifinalist. The remaining three pairings featured programs with deep Koshien history — including 2022 summer champion Sendai Ikuei, 2021 summer champion Chiben Wakayama, and Yokohama, which beat defending champion Okinawa Shogaku in Round 1.

Hashimoto allowed nine hits and three walks while stranding 14 Mie runners. It was his first appearance of the tournament — a left-hander deployed in the quarterfinal while Tenri rested ace Ryota Nagao, who had thrown consecutive complete games in earlier rounds.

How Tenri won

Resting the ace, trusting a left arm

Tenri manager Tadamasa Fujiwara did not start Nagao, who had completed his prior two Koshien outings. Instead, Hashimoto — who had not pitched at Hanshin until August 18 — took the mound against a Mie lineup that had posted 12 hits in each of its two prior tournament games and one of the tournament’s top batting averages.

The move was not simple rest. Mie had prepared against Tenri’s right-handed ace; opening with a left-hander with a different angle and velocity band forced an immediate adjustment. Hashimoto worked off his fastball, slider, and changeup, inducing contact and limiting damage rather than overpowering every inning.

The payoff: Nagao threw zero pitches on Day 13, preserving him for the semifinals while Hashimoto finished all nine innings.

Captain Kinbo Aoto drove the offense

Tenri captain and cleanup hitter Aoto Kinbo set the tone in the second inning. After a first-inning rally ended with a failed sacrifice and a double play, Kinbo worked a nine-pitch at-bat to a full count and homered to left on a 134 km/h fastball for a 1-0 lead.

Kinbo finished 2-for-5 with two RBIs and three runs scored. He homered with no one on in the second, stole second after reaching on an error in the eighth, and doubled to center on a full-count 136 km/h fastball in the ninth to drive in a run from second base. His production bookended the game — long ball to open scoring, speed to pressure the defense, long ball again to close it.

Lower-half lineup finished what the middle built

While Kinbo supplied the headline swing, Tenri’s 6th through 8th hitters manufactured the margin.

• Shota Maeda went 3-for-5 with two runs.
• Koto Otsuka went 3-for-3 with a sacrifice bunt in the four-run sequence.
• Norihiro Ozawa was 2-for-4 with two RBIs, including a two-out single in the fourth after he had struck out in a prior scoring chance.

From the sixth through eighth spots, Tenri batters combined for 8 hits in 12 at-bats with two RBIs. After Kinbo’s homer, the lower order added a run in the fourth on Ozawa’s two-out single and piled on in the eighth when Mie’s defense unraveled.

Mie: nine hits, zero runs

Mie was not overmatched at the plate. Hayato Akiyama collected three hits. The lineup put runners in scoring position in the second, third, fifth, sixth, seventh, eighth, and ninth innings.

What failed was conversion:

• In the second, consecutive singles put runners on first and second with one out, but Hashimoto struck out the 8th and 9th hitters back-to-back.
• In the third and fifth, Mie loaded situations with its top of the order but could not drive in a run from the 4th and 5th hitters, who went 0-for-9 combined.
• In the ninth, Akiyama doubled with two outs and a runner on third, but Tatsuma Tatematsu flew out to left to end the game.

Mie used four pitchers — Ueda, Kō Hashidate, Kaito Yoshii, and Maekawa — and allowed only four earned runs across seven scored by Tenri. Three unearned runs in the eighth, after three defensive miscues in one inning, turned a manageable 2-0 game into a rout.

Eighth inning: errors meet a relentless attack

Tenri entered the eighth leading 2-0. Kinbo reached on a second-base error, stole second, and advanced the pressure. After a fly out, Maeda’s grounder drew a bad throw to third; Otsuka followed with a right-field single, and Ozawa added a left-field RBI single as Mie’s right fielder mishandled another ball.

Three errors in one inning — combined with Tenri’s continued hitting — produced three runs. The burst mirrored Tenri’s approach all afternoon: not waiting for gifts, but running hard and swinging through defensive chaos.

The other three quarterfinal matchups

With Tenri’s win confirmed, three more quarterfinal games filled the rest of Day 13.

Sendai Ikuei vs. Chiben Wakayama

Sendai Ikuei, the 2022 summer champion, faced Chiben Wakayama, which won the 2021 summer title and reached the spring Koshien semifinals in 2025. The schools had met only once at Koshien — a 2007 first-round game Sendai Ikuei won 4-2 when ace Yuki Sato struck out 17 in a two-run complete game.

Both programs are coached by managers in their 40s who have already won a national championship: Kō Suga at Sendai Ikuei and Hitoshi Nakatani at Chiben Wakayama. Sendai Ikuei entered as a program chasing its fourth national title after becoming the fifth school ever to reach 50 summer Koshien wins earlier in the tournament; Chiben Wakayama sought its first summer crown since 2021.

Hanamaki Higashi vs. Yokohama

Hanamaki Higashi, the Ohtani Shohei alma mater and 2025 spring Koshien runner-up, met Yokohama, a perennial power that eliminated defending champion Okinawa Shogaku in Round 1. Hanamaki Higashi advanced with disciplined pitching relays and aggressive baserunning; Yokohama leaned on late-inning offense and dominant relief from ace Shoki Oda, who has repeatedly entered in high-leverage middle innings.

Pre-tournament analysis framed this as a contrast between Iwate’s staff depth and Kanagawa’s ability to change games in one inning — a recurring theme when schools from Japan’s industrial northeast meet Tokyo-area powers at Hanshin.

Kendai Takasaki vs. Ariake

Kendai Takasaki (Gunma), a spring Koshien regular with a deep pitching staff, faced Ariake, a first-time summer Koshien participant that had won three straight elimination games — each by overcoming a deficit. Ariake’s path included an emergency start when projected ace Ko was scratched before a Round 3 game because of a hand injury.

Kendai Takasaki beat Sano Nichidai 4-1 on August 16 using a four-pitcher relay; Ariake beat Tohin Daishohei 4-1 the same day with a three-run eighth inning. The quarterfinal paired Gunma’s structured rotation against Kumamoto’s comeback formula — one of the day’s clearest style clashes.

Discussion

Tenri’s 7-0 win was built on depth — a rested ace, a first-appearance left-hander, and a captain who homered early and doubled to center in the ninth.

1. Tenri rested Nagao after two straight complete games and handed the quarterfinal to Hashimoto, who had not pitched at Koshien until August 18. Does that rotation gamble look smarter now that Hashimoto threw 154 pitches in a shutout — or does the workload itself become the semifinal problem?

Mie put nine hits on the board and stranded 14 runners. Was Hashimoto’s outing proof that Tenri’s staff is deeper than its ace, or evidence that Nagao may still be needed for high-leverage innings later in the week?

2. Mie matched Tenri in hits but scored zero runs across nine innings. Is that a failure of the middle of the order — or did Tenri simply execute better in the innings that decided the game?

If Mie had converted one early scoring chance, the pitching matchup and managerial decisions might have looked entirely different. Where does this 9-hit shutout loss rank among Koshien quarterfinal heartbreaks?

Share your read on Tenri’s ceiling after a nine-year semifinal gap — and which of the three remaining quarterfinal matchups you expect to produce the other semifinalists on August 20.
