Kasumigaura Beat Naruto Uzushio 5-1 in Koshien Round 2 as Kikuchi Clears the Bases

On Friday, August 14, 2026, Kasumigaura High School — the Ibaraki Prefecture representative at the 108th Summer Koshien — defeated Naruto Uzushio High School of Tokushima 5-1 in the second round at Hanshin Koshien Stadium. Yuuichi Kikuchi delivered a bases-clearing triple in the third inning, ace Daiki Nishimura absorbed five early runs for Naruto Uzushio, and a Kobayashi-Inayama pitching relay held the line as Kasumigaura reached the round of 16 for the first time in two years and recorded the program’s first-ever two-win summer at Koshien.

Kasumigaura scored once in the second and erupted for four runs in the third, building a lead Naruto Uzushio could not overturn. The Tokushima side’s only run came in the fourth.

How Kasumigaura won

Third-inning burst: Kikuchi clears the bases

The turning point arrived in the bottom of the third. Kasumigaura loaded the bases against Nishimura, and Yuuichi Kikuchi — batting seventh in left field — ripped a three-run triple that cleared the bases and broke the game open. Japanese match reports described it as the afternoon’s decisive swing: a left-handed bat exploiting a right-handed ace who had been the centerpiece of Naruto Uzushio’s prefectural run and Round 1 marathon.

Combined with a run already pushed across in the second, Kasumigaura carried a 5-0 cushion into the middle innings — exactly the kind of middle-inning scoring burst manager Yuji Takahashi had envisioned when he told reporters before the game that his ideal was to score about five runs while holding Naruto to one or two.

Kobayashi and Inayama shut the door

On the mound, Kasumigaura turned again to its familiar left-right relay. Masahiro Kobayashi, a left-hander who touches the mid-130s km/h, started and worked through the early frames. Kota Inayama, the program’s ace right-hander who throws up to 148 km/h, entered in relief and closed out the win.

That pairing had already carried Kasumigaura past Chukyo in Round 1 on August 9, when Kobayashi went 6⅓ innings and Inayama finished with 2⅔ scoreless on just 48 pitches. Against Naruto Uzushio, the relay limited Tokushima to one run on four hits after the early Kasumigaura rally — the same formula Takahashi used throughout the Ibaraki prefectural tournament, including the 9-7 final win over Joso Gakuen.

Naruto Uzushio’s lone answer

Naruto Uzushio finally scratched across a run in the top of the fourth, trimming the deficit to 5-1. But the lineup that had clawed back close games throughout the Tokushima bracket — including a walk-off in the prefectural semifinal and a come-from-behind win in the prefectural final — could not mount a second rally against Kasumigaura’s staff.

Nishimura, who had thrown 10 innings and 128 pitches in a 2-1 extra-inning Round 1 win over Hachioji Jissen on August 9, was charged with five runs before the game was effectively decided. Manager Yasuhito Mori had leaned on his ace throughout the Tokushima tournament and again in the opener; on August 14, the early damage proved too much to overcome.

Paths to the second round

Both schools entered Day 10 on four days’ rest after winning on August 9, but the workload behind those wins looked nothing alike.

School	Round 1 (Aug. 9)	Pitching notes
Kasumigaura	6-3 over Chukyo	Kobayashi 108 pitches through 6⅓ IP; Inayama 48 pitches in 2⅔ scoreless IP
Naruto Uzushio	2-1 over Hachioji Jissen (10 inn.)	Nishimura 128 pitches, complete game in extra innings

Naruto Uzushio was the only school among the 49 representatives that won its prefectural title without using the designated hitter — Nishimura batted third and pitched every key game in Tokushima. Kasumigaura, by contrast, used the DH and kept Inayama fresh enough to deploy either as a starter or a closer.

Pregame analysis from Sports Bull highlighted the contrast: Naruto’s identity was protecting a one-run lead deep into games; Kasumigaura’s was stacking runs in the middle innings after falling behind. On August 14, Kasumigaura’s profile won the matchup.

What the result means

Kasumigaura’s historic second win

The victory gives Kasumigaura two wins in a single Summer Koshien for the first time in program history — a milestone the Ibaraki side had explicitly targeted all summer. The school is making its fourth Summer Koshien appearance and its second in two years, having lost in Round 2 in 2024 and 2025.

Kikuchi’s breakthrough added a human layer to the scoreboard. The third-year outfielder was left off the initial tournament roster before the Ibaraki prefectural run, spent stretches outside the everyday lineup, and only became a central figure late in the prefectural tournament — including four hits and four RBIs in the 9-7 final. His third-inning triple at Hanshin Koshien was the kind of payoff manager Takahashi had described when he praised Kikuchi as a diligent player who had struggled to translate practice form into game production.

Naruto Uzushio’s run ends in Round 2

For Naruto Uzushio High School, the loss ended a memorable but short national run. The Tokushima champions earned their first Koshien victory under the school’s current name with a walk-off in Round 1 — the program’s first summer win since the Naruto Kogyo era in 2008. Nishimura’s 10-inning effort against Hachioji Jissen was the kind of ace performance that made Naruto Uzushio the last remaining public school in the bracket.

With Naruto Uzushio’s elimination, all nine public-school representatives were out of the tournament by the end of Round 2 — a storyline Japanese media tracked closely on Day 10.

Bracket context

Kasumigaura advances to Round 3 on August 16 (Day 12, Game 4), where it will face the winner of Minami Gakuen (Miyazaki) vs. Yokohama (Kanagawa) — the August 14 nightcap on Day 10. Three North Kanto schools — Kasumigaura, Hanamaki Higashi, and Sendai Ikuei — reached the round of 16 on the same day, giving the region a rare cluster of teams in the national quarterfinal hunt.

Discussion

A five-run third inning turned Naruto Uzushio’s ace-led formula inside out — and sent Kasumigaura into uncharted territory with two summer wins at Hanshin Koshien.

1. Nishimura threw 128 pitches across 10 innings just five days earlier, then gave up five runs in the first three frames. How much did Round 1 workload matter — and would Naruto Uzushio have needed a different pitching plan to stay alive against Kasumigaura’s middle-inning attack?

Tokushima built its summer around one arm who also bats third. Was that always a Round 2 risk?

2. Kikuchi was not on the initial roster and spent much of his career fighting for playing time. Does a bases-clearing triple in a program-first two-win summer change how you read Kasumigaura’s ceiling — or is one hot bat still just one afternoon?

Ibaraki next faces either Yokohama or Minami Gakuen. Where do you rank Kasumigaura among the remaining contenders?

Share your read on whether Kasumigaura’s relay can survive a third game — and what Naruto Uzushio’s exit means for public-school baseball at this Koshien.
