It was decided on the 12th that the Softbank Hawks will face Nippon-Ham in the CS Final Stage (opening on the 14th at Mizuho PayPay Dome). Although Shinjo's Nippon-Ham allowed the Seibu Lions to take the lead in the first stage, they secured a comeback victory with consecutive wins. Starting this season, new CS rules have been introduced, and for the first time, a 'two-win advantage (conditional on a lead of 10 games or more, or a winning percentage below .500)' will be applied to the Softbank Hawks. The series will be conducted as a maximum seven-game system (first to five wins).

The Hawks achieved their third consecutive championship by winning the season series against every team in the same league for the first time in 60 years. This season, they overwhelmed Nippon-Ham, with whom they fought for the league title last season, recording 18 wins, 5 losses, and 2 draws, including a franchise-first 8-game winning streak from the season opener. Particularly at their home stadium, Mizuho PayPay, they went 10-1, including a 7-game winning streak from the start. The team's batting average against Nippon-Ham was a Pacific League-leading .291, and their 31 Home Runs and 155 runs scored were also the highest. Led by Taisei Makihara's .417 (35 hits in 84 At Bats), Masaki also recorded his best average against a specific opponent at .329. Kurihara, who this season became the first player in the franchise to hit 40 home runs in 21 years since Nobuhiko Matsunaka in 2005, also produced 8 Home Runs against them, tied for his most against any team along with the Seibu Lions. Kondo also maintained stable performance with a .304 average and racked up a matchup-high 25 RBI.

Regarding the pitcher staff, Moinelo, who is expected to start the first game, has a strong record this season with 2 wins and 1 loss in 3 games and an ERA of 1.33. Uwasawa also matches up well, with 3 undefeated wins in 7 starts and an ERA of 2.20. There seem to be no blind spots in their quest for a third consecutive Japan Series appearance and their first consecutive Japan Series titles since the four-year streak ending in 2020 under Kimiyasu Kudo.
