They compete in the Pacific League of Nippon Professional Baseball, playing the majority of their home games at ES CON Field Hokkaido.

The Fighters also host a select number of regional home games in cities across Hokkaidō, including Hakodate, Asahikawa, Kushiro, and Obihiro.

Tokyu purchased the team to act as a banner of solidarity for the swelling company, and managing director Hiroshi Okawa assumed ownership of the club.

The newly born Flyers, with Hiroshi Oshita becoming one of the most popular players in the league, began to attract many fans, but the team's administration still went into a deficit.

In 1961, when Yomiuri Giants manager Shigeru Mizuhara resigned from his position, Okawa attempted to woo him to join his team, bringing him to a bar in Kyoto and calling famous movie producer Koji Shundo to meet with them.

Shundo, an old drinking buddy of Mizuhara's, convinced the four-time Japan Series champion manager to join the Flyers, and he solidified a strong relationship with Okawa and Toei Studios.

In the same year, two star aces, Masayuki Dobashi and Yukio Ozaki, blossomed under Mizuhara's coaching and the Flyers captured their first league championship.

The team was sold to Akitaka Nishimura of the Nittaku Home real estate enterprise, a common acquaintance of Okada and Goto, on February 7, 1973.

He loved them to death, so much so that he never held any company meetings when the team was playing, and if where he was at, they were not on TV or radio, he would dispatch employees to go to that game and update him via payphone.

With saves leader Yutaka Enatsu and starter Shigekuni Mashiba (who went 15–0 over the season) forming the heart of the pitching staff, the Fighters shined with offensive sluggers Tony Solaita, Junichi Kashiwabara, and Tommy Cruz.

Hitters such as Nigel Wilson, Jerry Brooks, Yukio Tanaka, Atsushi Kataoka, Katsuhiro Nishiura and a young Michihiro Ogasawara formed what became known as the Big Bang lineup and subsequently shattered various batting records.

As a matter of fact, the question of reorganizing baseball's league structure eventually became a bigger issue than the sale and renaming of the Kintetsu Buffaloes.

The response from the people of Hokkaidō was weak, but NPB fans welcomed the move, noting that the Fighters could now be free from the Tokyo Dome's high rent and perpetual second-billing to the Giants.

After the move finally was complete in 2004, the Fighters signed former-Tigers superstar Tsuyoshi Shinjo, who came back to NPB from MLB after playing with the New York Mets and nearly winning a World Series title with the San Francisco Giants and a revitalized Fernando Seguignol.

American manager Trey Hillman led the team to success in his second year on the job, and at the end of the season, the Fighters were in a fierce race with the Chiba Lotte Marines for the final spot in the new P.L.

With a vital win over the Orix BlueWave on September 24, the newly moved Fighters earned a trip to the postseason, advancing to play Seibu in a three-game series.

[2] During the pennant race, the Fighters began selling tickets for infield reserved seats at a low 1,500 yen price point, in an attempt to draw fans to the park.

In the offseason, the Fighters acquired Major League veteran José Macías, and as former number one starter Yusaku Iriki tried his luck in America, the club attempted to sign Kazuhisa Ishii, but failed.

[3] The championship win was especially fitting for OF Tsuyoshi Shinjo, who was a longtime veteran of the Hanshin Tigers (who were perennial losers), and also had played for a brief time in the United States' Major League Baseball.

This victory gave the Fighters a berth in the four-team Asia Series, in which the team went undefeated in the round-robin and won the final 1–0 over the La New Bears.

First baseman Michihiro Ogasawara was signed to a blockbuster contract with the Yomiuri Giants, and left-handed reliever Hideki Okajima departed to the Boston Red Sox.

With the start of Interleague play, Nippon-Ham began a 14-game winning streak, which ended on June 9 with a 3–2 extra inning loss to the Yakult Swallows, with the bullpen wasting another great performance by Darvish.

Kiyomiya was also being plagued by injuries, whilst Murakami managed to stay healthy and has played the full 143 game schedule with the Swallows.

[8] On September 28, 2022, the Fighters played their final game at Sapporo Dome, an 11–3 loss to the Chiba Lotte Marines and the team finished the season with the worst record in the NPB.

Among individual accomplishments included Chusei Mannami winning his second Golden Glove award, new foreign signing Franmil Reyes making the Best Nine for the Pacific League, alongside breaking Fernando Seguignol's Fighters record for most consecutive games with a hit at 25 games, and Shun Mizutani, whom the Fighters acquired from the Hawks in the active player draft, having a breakout season, culminating in him winning Interleague MVP.

Due to the COVID-19 pandemic disallowing any cheering or singing at games, she wanted to make a choreographed dance that would be simple for anyone to memorize, especially children.

[11] Fighters Girl members, alongside Japanese idol group Hinatazaka46, performed the song during the Kohaku Uta Gassen annual concert on New Year's Eve on December 31, 2022.

[12] Notable names that done the dance with Fighters Girl include actress and former Takarazuka Revue member Sei Matobu, Japanese idol group Nogizaka46 member Saya Kanagawa, and Fox Sports analyst and brother of MLB pitcher Justin Verlander, Ben Verlander,[13][14] amongst other people, including opposing team's cheerleading squads.

The dance has also found itself being performed in a few areas thanks to its popularity, including one by the cheerdancing squad of CPBL team Rakuten Monkeys (which is also thanks in fact that the club is owned by Rakuten, the same company who owns the Tohoku Rakuten Golden Eagles of NPB),[15] another by J.League club Cerezo Osaka (due in part to the club being partially owned by Fighters owner Nippon-Ham),[16] and it appearing in multiple shows in Japan, including a performance during an annual event sponsored by Nippon TV, with NPB players Naoyuki Uwasawa and Shugo Maki.

The dance was also upgraded on the 29th of April to coincide with the beginning of Golden Week in Japan, adding sheep ear headbands to the cheerleaders.
