SoftBank led the league for the majority of the season, never relinquishing first place after taking the top spot on April 4th.

[6] In the Central League (CL), the Hiroshima Toyo Carp were narrowly in first place at the end of August.

A fourth Carp loss in a row on October 2 confirmed that the Yokohama DeNA BayStars would clinch third place and their third straight trip to the Climax Series.

[9] First-year team captain Shugo Maki and eventual 2024 batting champion Tyler Austin powered the DeNA offense, while ace Katsuki Azuma led the pitching staff with thirteen wins.

[10][11] From the start of the season, Azuma won eight straight games, helping the BayStars reach second place by the end of June.

[10] Still in fourth and outside of Climax Series qualification on August 27, Maki introduced the motto "determined to win" to the team.

[15] The sweep advanced DeNA to the final stage, where they faced off against the CL-champion Yomiuri Giants at the Tokyo Dome.

[17] BayStars manager Daisuke Miura was a starting pitcher for the team the last time that they won the title 26 years ago in 1998, only their second championship.

They finished the regular season only two games above .500, for a final winning percentage of .507, the lowest of any Japan Series team.

Before the start of Game 1, Nobuteru Maeda of the band Tube sung the Japanese national anthem, and Hall of Famer Hiroshi Gondoh, the former BayStars manager that led the team to its last Japan Series championship in 1998, threw out the ceremonial first pitch.

[17] Arihara pitched seven scoreless innings for the Hawks, allowing four hits and two walks while striking out four batters.

In his 4+2⁄3-inning start, Jackson struck out a total of nine batters, issued four walks and allowed two runs on three hits.

[34] In the ninth inning, two SoftBank singles put runners at first and second bases and Kenta Imamiya hit a double to score both.

[34] The next at bat, Shugo Maki flew out with the potential tying runs on base to end the game 5–3.

[32] Game 2 featured starting pitchers Liván Moinelo for SoftBank and Shinichi Ohnuki for the DeNA.

[36] Austin, one of the BayStars' most important offensive players, did not play after being hit in the left foot by a ball in Game 1.

[37] In the top of the first inning, all three outs were swinging strikeouts by Ohnuki, however he gave up three hits, including a two-run home run by Hotaka Yamakawa to give the Hawks an early 2–0 lead.

Moinelo continued to pitch into the seventh inning until he was removed from the game after giving up two consecutive singles that ultimately allowed Maki to drive in DeNA's third run via a double.

[37] Game 3's national anthem was sung by Atagi of the musical trio Awesome City Club and the ceremonial first pitch was thrown out by Olympic gold medalist breakdancer Ami Yuasa.

It was the first game the BayStars' ace pitched in since hurting his hamstring running the bases during the first stage of the CL Climax Series.

[40] The BayStars opened the game with a leadoff double by Kuwahara in the first inning and, after a sacrifice bunt advanced him to third base, a ground out allowed him to score.

In the bottom half of the inning, the Hawks tied the game with the help of sloppy defensive play from the BayStars.

SoftBank relief pitcher Ryosuke Ohtsu came into the game in the fifth inning and immediately gave up a solo home run to Kuwahara.

Following the home run, DeNA loaded the bases with no outs and Yoshitomo Tsutsugo hit a sacrifice fly to increase the lead to 3–1.

[41] Toshiro Miyazaki hit the BayStars' second solo home run of the game to lead off the seven inning against the Hawks' bullpen.

Game 3 starting pitcher Carter Stewart Jr. entered the fifth inning in relief after the Hawks' two runs in the fourth to cut the BayStars' lead to 4–2.

[47] Stewart loaded the bases and then walked Kuwahara and gave up a single to Kajiwara to bring the score to 6–2 and end his inning after only recording one out.

DeNA's Yoshitomo Tsutsugo, Andre Jackson, and Anthony Kay were all named as recipients of the Outstanding Player Award.

[51] A victory parade through Minato Mirai 21, Yokohama's central business district, featuring a player motorcade was held on November 30 to honor the team and its championship.

[60] In response, NPB stripped Fuji TV of its press passes to cover the entire Japan Series prior to the first game.
