History shapes the rivalry; it cannot decide the first pitch of 2026.
The unlikely challenger and the 91-win favorite
The 2026 Japan Series opens at Yokohama Stadium at 6:30 p.m. Japan time on October 24, with the Yokohama DeNA BayStars hosting the Fukuoka SoftBank Hawks. DeNA went 71–69–3 and finished third in the Central League; SoftBank topped the Pacific League with a 91–49–3 record and a .650 winning percentage. Their qualification routes were strikingly different. DeNA won six postseason games in succession, while SoftBank swept its final-stage series against the Nippon-Ham Fighters. The matchup is official; a championship outcome is not.
How DeNA pulled off six October wins
The BayStars beat the Yomiuri Giants 2–1 and 4–1 at Tokyo Dome on October 10 and 11. Against the Hanshin Tigers at Koshien, they then won 2–0, 1–0, 4–0 and, on October 17, 8–5. The first three wins over Hanshin were shutouts. That sequence helps explain how a third-place club secured a championship berth. It does not prove the BayStars have become the strongest regular-season side, nor does it guarantee their pitching will remain as effective against a different opponent.
SoftBank arrives after 91 regular-season victories
The Hawks reached the final stage directly as Pacific League champions and beat Nippon-Ham 6–4 on October 14, then 6–2 on both October 15 and 16. NPB records list Liván Moinelo, Kōhei Uwasawa and Yūto Maeda as the starters in SoftBank’s three final-stage victories, but a Japan Series Game 1 starter should not be guessed before an official announcement. SoftBank’s record indicates season-long consistency; what matters in a best-of-seven final is how the club distributes its pitching and adapts to DeNA.
The history runs through 2017 and 2024
The franchises met in the 2017 Japan Series, when the Hawks won four games to two, clinching Game 6 in the 11th inning. In 2024, SoftBank won the first two games in Yokohama. DeNA then won four in a row, including three on the road, and clinched the title with an 11–2 Game 6 victory. That championship was the BayStars franchise’s third and first in 26 years. The history makes the rematch compelling, but it is not a statistical forecast. Short series can swing violently on pitching, defense and a handful of plate appearances.
Why a third-place team can play for the title
Japan’s Climax Series, introduced across both leagues in 2007, separates the pennant race from the playoff route to the Japan Series. The regular-season league winner receives a structural advantage in its final-stage playoff, yet a lower finisher can still reach the championship by winning in October. DeNA is the Central League postseason representative, not the 2026 Central League pennant winner. SoftBank combines the Pacific League pennant with a successful postseason run. Understanding that distinction is important for international fans accustomed to different playoff structures.
The pitching matchups are more complex than one ace
DeNA held Hanshin scoreless over the first three games of their final-stage contest, while SoftBank scored exactly six runs in each of its three games against Nippon-Ham. But the opponents, ballparks, defensive alignments and game situations differed. The Hawks’ .650 regular-season mark is evidence of depth; the BayStars’ October streak is evidence of performance under short-series pressure. Neither metric can independently predict the title. Official Game 1 starters, healthy rosters and late player transactions remain essential pregame checks.
Two cities, two very different baseball environments
The first two games take place at open-air Yokohama Stadium, on October 24 at 6:30 p.m. and October 25 at 6 p.m. After a travel day, Games 3–5 are scheduled for October 27–29 at the roofed Mizuho PayPay Dome Fukuoka, all at 6 p.m. If needed, the series returns to Yokohama for October 31 and November 1. Ballpark geometry, weather and the rhythm of travel may influence tactics. But any claim of a measurable home-field advantage requires evidence rather than intuition.
The champions of 2024 and 2025 collide
DeNA lifted the 2024 Japan Series trophy after reversing a two-game deficit against SoftBank. A year later, the Hawks beat the Hanshin Tigers four games to one, securing their 12th Japan Series title and first since 2020. The 2026 final consequently brings together the winners of the previous two championships. SoftBank can attempt to defend its crown; no 2026 title has yet been awarded. The clubs’ histories should enrich the present matchup rather than overwhelm the reporting on this season’s actual players.
The Japan Series is also a civic event
A championship baseball week connects two distant commercial regions: Yokohama, a port city beside Tokyo, and Fukuoka, the major gateway of Kyushu. Fans travel, businesses around stadiums see a rush of attention, and local identity is amplified. It is tempting to attach a large economic-impact estimate to the series, but there is no verified new independent estimate for this matchup. NPB organizes the competition, with Sumitomo Mitsui Banking Corporation as its special sponsor, and publishes official ticketing and postponement rules.
What to watch once the first pitch is thrown
DeNA’s story is no longer simply that it finished third. It eliminated the Giants and swept the Tigers in four games after the first stage. SoftBank’s is no longer only that it won 91 games. It earned its berth by beating Nippon-Ham three times. The real analytical questions are how pitchers are deployed, whether early leads change bullpen decisions, and which defense handles crucial moments. A trustworthy preview stops where evidence stops: the opening pitch is October 24, and the matchup’s winner remains unknown.
What remains to verify before Game 1
Official Game 1 starters, final eligible-player lists, late injuries, ticket updates and any schedule adjustments must be verified directly with NPB and the clubs. They are not inferred here.
