Match Information

Three Things to Watch

1. 3-4-2-1 vs 4-2-3-1 — the wing-back vs side-midfielder duel decides the flanks Hiroshima's 3-4-2-1 with both wing-backs pushing high, attacking, vs Kawasaki's 4-2-3-1 with its side-midfielder and full-back link. The matchup between Hiroshima's Toshiki Higashi (PI +27) and Kawasaki's full-backs / side-midfielders decides the flank advantage.

2. Hiroshima's Tolgay (PI +42) vs Kawasaki's GK Rui Yamaguchi (+29 core) — high-impact subs vs a core axis Hiroshima's Tolgay (+42 in 6 games) carries big impact in short minutes. Kawasaki, by contrast, are anchored by GK Rui Yamaguchi (+29 in 35 games, core) and MF Yuki Yamamoto (+21 in 38 games, core) as a stable core axis. The question is whether the two opposite-styled sides seize control through sub usage or through core minutes.

3. "Home momentum" vs "short-tie experience" — Leg 1 at Edion Peace Wing Hiroshima Hiroshima are West 4th with momentum at +8 goal difference; Kawasaki are East 4th at −4. In Leg 1 at Hiroshima's new home, will they ride the momentum to score first and hold on, or will Kawasaki chase an away win on "short-tie experience"? The two managers' strategic choices diverge.

① 3-4-2-1 vs 4-2-3-1 — the wing-back vs side-midfielder duel decides the flanks

Hiroshima's (manager Bartosch Gaul) 2026 season was nearly fixed with 3-4-2-1 in 16 of 18 games. The other two were 3-4-3 / 3-4-1-2, both back-three-based experiments. It is an attacking shape with both wing-backs pushed high and two shadow strikers tucking inside.

Kawasaki (manager Shigetoshi Hasebe) used 4-2-3-1 in 15 of 18 games, with 3-4-3 / 4-4-2 / 3-4-2-1 once each — traces of trial and error. They used 4-2-3-1 in the most recent R18 as well, so their current "answer" is a back four.

Matchup structure: if Hiroshima's two wing-backs in the 3-4-2-1 (left Toshiki Higashi, PI +27, right a full-back-type player) push high, Kawasaki defend through the link between their two side-midfielders (Akihiro Ienaga, PI +16 / others) and full-backs (Sota Miura, PI +11, core). Hiroshima's wing-back surges impose a defensive burden on Kawasaki's side-midfielders.

Conversely, if Kawasaki's No. 10 and side-midfielders take the spaces beside Hiroshima's three center-backs, a "central penetration from the flanks" that rarely emerges in 4-4-2-type setups becomes possible. Which flank, left or right, creates a situation first in Leg 1 sets the pace.

② Hiroshima's Tolgay (PI +42) vs Kawasaki's core axis (Rui Yamaguchi, Yuki Yamamoto) — high-impact subs vs a stable core

The biggest number in Hiroshima's PI ranking belongs to Tolgay (PI +42 in 6 games). His impact in short minutes is large, and his impact when used is Hiroshima's PI top. Together with Naoki Maeda (PI +17 in 12 games), he forms the attacking core in a "short-minutes, high-PI" supporting-cast mold.

Kawasaki, by contrast, are a stable side, and their PI leaders are a core axis. Rui Yamaguchi (GK, +29 in 35 games, core), Yuki Yamamoto (MF, +21 in 38 games, core), Akihiro Ienaga (FW, +16 in 14 games), Yasuto Wakizaka (MF, +12 in 43 games, core), Sota Miura (SB, +11 in 33 games, core) — built from long-minutes core players. Shigetoshi Hasebe has chosen a stable, core-centered operation.

What to note is the low PI of Hiroshima's core players. Shun Kawabe (MF, −27 in 45 games, core), Sho Sasaki (DF, −30 in 42 games, core), Tsukasa Shiotani (CB, −17 in 42 games, core), Ryo Germain (FW, −43 in 41 games, core) — core regulars sit low on PI together. Hiroshima carry a structure where "high-PI subs carry the attack while the core regulars drag down the goal pace."

The starting lineup's "core vs sub ratio" becomes the factor that decides both sides' game. Can Hiroshima secure the minutes for Tolgay on the pitch? Can Kawasaki sustain 90 minutes without exhausting the core axis? Opposite squad philosophies collide in this match.

③ Home momentum (Hiroshima) vs short-tie away strategy (Kawasaki) — the strategic dilemma

Hiroshima are based at Edion Peace Wing Hiroshima, opened in 2024, and are reputed to be strong at home. Their 30 points / +8 goal difference are top-end momentum among West 4th-class sides. Win Leg 1 at home and they can build a structure that is favorable even carrying a 90-minute draw forward in Leg 2 away (Uvance Todoroki).

Kawasaki, by contrast, are East 4th at 28 points / −4 goal difference — level on points with 5th-placed Tokyo Verdy, and the most up-and-down of the East's top four clubs. It is a binary choice: chase an away win in Leg 1 or prioritize a clean sheet. Shigetoshi Hasebe is a manager who has fine-tuned his formation game by game, and his Leg 1 formation choice will be the first sign of "short-tie mode."

Both sides' strategic dilemma:

• Hiroshima: (A) Push the wing-backs high in 3-4-2-1 to chase the opener / (B) Hold the wing-backs back in a 3-4-3-type shape and bet on a 0-0 carry-over
• Kawasaki: (A) Go for the opener from the No. 10 in 4-2-3-1 / (B) Match up against Hiroshima's 3-4-2-1 with 4-4-2 or 3-4-2-1

The Leg 1 formation reveal becomes the first sign of each manager's strategy of "focusing on the game in front of them and securing overall 7th place for certain."
