The JD.League is a member of the Japan Top League Alliance, which comprises the top-tier sports leagues in Japan.[1] Nitori entered into the title partnership with the JD.League, and thus the league is officially called Nitori JD.League.[2]
The first national women's softball league was founded in 1968, as the Japan Softball League. In 1994, the league's First Division expanded from 8 to 12 teams and adopted a postseason with the page playoff system. Since then, this season's format was lasted until 2021, although there were minor changes.
In 2021, the league announced a new top-tier women's softball league is planned for 2022, the Japan Diamond Softball League (JD.League).[3] All 12 teams from the First Division and four teams from the Second Division, i.e., 16 teams in total joined in the new league.[4] The other remaining teams in the Second/Third Division and several fresh teams formed the reborn Japan Softball League.
The opening game of the JD.League was held between Bic Camera Takasaki Bee Queen and Toyota Red Terriers on March 28, 2022.[5] Meanwhile, the Japan Softball League still exists as a de facto lower-tier league.
Until now, the league is an industrial league, where most of the teams are owned by major companies and many players are their companies' employees. A player who is signing a professional contract is only a small portion.[6][7]
The JD.League consists of 16 teams divided into two divisions with 8 teams each.

The JD.League's regular season runs from late March to late October, with each team playing 29 games. The league's postseason tournament extends into mid-November. The league has a fixed membership like NPB and most sports leagues in the United States, which makes it that does not use a promotion and relegation process.[24][25][26]
The JD.League consists of two divisions, the East Division and the West Division, which each has 8 teams. Each team plays 21-game Division Series against the seven other teams in its division, i.e., one home series, one away series and one neutral-site series. Furthermore, each team plays 8-game Inter-division Series against each team in the other division. Following the conclusion of the 29-game regular season, seven teams (the top three teams in each division and one wild card team) advance to a postseason tournament that determine the Grand Champion.[24]
Following the conclusion of the regular season, seven teams compete in the four-round postseason tournament (the two-round Playoffs and the two-round Diamond Series) with a single-elimination stepladder format.[24]
Each division winner directly advances to the Diamond Series. The second-place and third-place teams in each division, and the wild card team (either fourth-place team in each division with better winning percentages) advance to the Playoffs, that culminates in the Diamond Series.[24]
The Diamond Series is contested among the four teams (two division winners and two Playoffs winners) to determine the Grand Champion. The winner of the Diamond Series is referred to as the Grand Champion of JD.League.[24]
